Adjustment Steps of Supporting Rollers of Rotary Kiln

Before the adjustment of the supporting rollers of the rotary kiln, you must find out the shifting reasons according to the shifting situation of the kiln body to avoid the blindly actions. When the rotary kiln begins to rotate, all the shaft axis of the supporting rollers must be parallel to the centerline of the kiln body. If the shifting amount of the kiln body does not exceed a given range, it can be regarded as the normal phenomenon. The contact surface of the supporting rollers and the rolling ring is uniform. The contact width of the surface of the rolling ring should be more than 80%. The contact of the two rollers should be in symmetric state at the central part of the contact. If there is no abnormal phenomenon in the kiln body, the operation of the rotary kiln is the most normal.
If the pressure of the upper damper and the lower damper is too large, you should check the contact of the damper and the rolling ring, and the stress situation of the bearings of the supporting rollers according to the superheat of the bearing of the damper. You can select one pair or two pairs of supporting rollers for adjustment until the operation of the rotary kiln is normal. However, the adjustment angle of the supporting rollers should not be more than 30. In the installation process, the deflection of the central line of the supporting rollers and the central line of the kiln body should not be more than 1.5mm to 2mm. At the same time, in order to ensure that there is a fixed contact surface of the supporting roller and the rolling ring, the supporting roller after the adjustment should make the two center distances of the two shaft ends of the supporting roller equal.
In this paragraph, we will introduce the adjustment steps of the supporting rollers of the rotary kiln. First, you had better start from the supporting rollers at the kiln end when you need to adjust the supporting rollers. Second, try to make the central line of the supporting rollers at the kiln head and near the firing zone and the central line of the kiln body maintain paralleled.  The central line can be moved only necessary so that to ensure normal operation of the rotary kiln.

Dynamics Model of Vibrating System of Roll Crusher

The roll crusher is to use the relative vibration of the two rigid bodies to apply high-frequency shock to the granular layers so that the particles can be crushed. The roll crusher has the advantages of large crushing ratio and fine granularity of the products, which can also achieve the selective crushing and layer crushing. In addition, the roll crusher produced by Henan Hongxing Mining Machinery also makes full use of the resonance vibration, impact energy and other advanced design ideas. Therefore, the roll crusher also has the advantages of small exciting force, small bearing load, long service life and others. For the roll crusher in the actual application, the degree of freedom of movement of the rigid body system is 6. Obviously, in strongly nonlinear vibration system with complex rigid body motion, we must have deep analysis of the mechanism and the laws to study the coupling effect. Therefore, we should first study the unilateral vibrating impact system.
The roll crusher is a kind of vibrating system which is composed by two vibrating rigid bodies and the broken loose bodies. The primary moving jaw does the forced vibration with the excitation vibration of the eccentric exciter. The primary moving jaw and the secondary moving jaw is connected by the master vibration spring which passes the vibration to the secondary moving jaw to cause the vibration. Put a vibration isolation rubber spring between the secondary moving jaw and the foundation to reduce the spread of the vibration to the outside world.
After the study of the nonlinear dynamics in the vibrating impact crushing process, we can use the simplified vibrating crushing system, namely single mass vibration impact crushing system for system study of the coupling nonlinear dynamics in the actual vibrating crushing process. We can use the nonlinear resonance principle and impact crushing principle with multiple-degrees freedom to carry out the theoretical analysis and experimental study of nonlinear dynamics of the roll crusher in the vibrating crushing process.
The main results are as follows. First, through the compression crushing test in the rigid metal container within the particle layers, we can get the changing laws of the structure relationship of the layer in the pressure of loads. Second, the single mass coupling vibrating impact crushing system has been established. Compared with the impact breaker and cone crusher, the new generation of roll crusher can better achieve the crushing purposes.

The Working Mechanism Basis of Impact Crusher

Currently, there are two main types of the extrusion and fracture of materials, namely single particle crushing and the laminated crushing, which are also the main basis for the structure design and working mechanism of the impact breaker. This article will briefly explore the single-particle crushing and the laminated crushing.
First, the experts of Henan Hongxing Mining Machinery will introduce the single particle crushing for you.
In the usual sense, the coarse crushing and medium crushing of the ore belong to the single particle crushing. For the single particle extrusion and crushing, there are three different loading methods. When the materials withstand the point loads, the slope of the strain curve is small, which means that the curve is nearly flat. This is because the materials on the carrier point withstand the high partial pressure. When the materials withstand the line loads, the slope of the strain curve becomes steep. In the uniaxially loaded state, the slope of the strain curve of the material is the steepest, and shows the relationship between the load of the solid materials. The single-particle crushing process is usually carried out in the single loading state.
The single particle crushing of the materials can be broadly divided into the following four stages. The first is the crack propagation caused by the stress concentration. The second stage is to generate a large number of micro-cracks. The third stage is to form the surface cracks. The forth stage is that the particles are crushed to form new surfaces.
Second, the experts of Henan Hongxing Mining Machinery will introduce the laminated crushing for you.
The laminated crushing is different from the single-particle crushing. The laminated crushing means that the crushing refers that a particle has contact with other particles. When the materials are crushed, the contact between the particles will produce the crushing form with interaction. The effective crushing stroke of the crushing cavity forms many particle layers with high density, then the sufficient crushing force is acted on the particle groups of the materials. When the laminated crushing is fully used, we can make full use of the kinetic energy of the crushing to crush the neighboring materials to obtain high crushing rate.

Analysis about Workshop Section of Sillimanite Brick

The sillimanite bricks are more and more widely used in the production of the industry and they are becoming more and more important. This article will introduce the workshop sections of the sillimanite brick,
The first workshop section is the raw materials section of the pick and crushing workshop section.
The main raw material bauxite clinker enters the raw materials warehouse in clumps. After the manual sorting for the materials, they are sent to the jaw breaker for coarse crushing. Then the materials are sent to the cone crusher for fine crushing.  The materials after crushing are screened by the double sieve to screen three kinds of granule. The materials on the sieve return to the cone crusher for crushing again. The rest of the particles enter the stock bin for storage. Three kinds of particles can enter the tube mill for pulverizing. After the soft clay is crushed, it directly enters the hanging roller mill to be processed to the clay fine powder. Then it enters the ingredients warehouse for storage.
The sillimanite concentrate, bauxite, corundum and other raw materials are purchased as the finished granules or powder. They are firstly stored in the warehouse of raw materials, and sent to the ingredients section by the hutching according to the dosage. Then they are stored in the ingredients compartment.
The second workshop section is the ingredients mixed section.
The ingredients work of the main raw materials is completed by one electronic batching car. The materials after the blending process are directly put on the muller. In addition, add small amount of material, such as the solid binding agent, water, etc., In the kneading process, the materials after manual weighing are directly put into the muller. The materials after mixing are discharged into the mud tank and sent to the forming section by human mud tanker.
The forth section is the forming section.
The modeling of the sillimanite brick can be completed by one 300-ton friction brick machine and two sets of 400-ton friction brick machine. After molding, the green bricks are directly put on the drying machine and sent to the dry firing section.
The forth section is the dry firing station. 
After the green bricks are naturally dried in the drying room for certain time, they are sent to the tunnel drier for drying by a three-tons electrical trailer. The temperature of the cold end of the dryer should be 50° C to 70 ° C, while the temperature of the hot end should be 150° C to 170 ℃. The moisture of the green brick after drying should be less than 2%.

Production Process Analysis of Cement Rotary Kiln

The production process of the cement rotary kiln is very complex and the production equipments are diverse. There are large numbers of 1 / O points, and the distribution is dispersed. Therefore, the framework of the control system with reasonable design is extremely important for the   further optimization of the production process and the technological innovation. There is a wide range of the furnace. According to the different working principles, they can be divided into roller kiln, rotary kiln, shaft kiln. According to the applicable materials, they can be divided into the glass furnace, ceramic kilns, cement kilns and so on. The cement rotary kiln includes the precalciner kiln, preheater kiln, dry kiln, and wet kiln. The cement rotary kiln with decomposing furnace outside the kiln which is also known as precalcining has become the new direction of the development of the cement rotary kiln due to the high labor productivity, strong operability and good quality of the products. Therefore, improving the production efficiency, improving the control method and designing the intelligent monitoring system of the rotary kiln has very important significance.
From the 1960s to the 1980s, the foreign cement production technology experienced two stages of development. The first stage is from the wet method to new dry process production of the preheater kiln. The second stage is from the precalciner kiln to preheating kiln. In recent years, the world's cement industry development direction obviously tends to the dry precalciner kiln. The dry process cement production regards the suspension preheater and the decomposition technology outside the kiln as the core. The achievements of the modern science and technology and industrial production are widely used in the whole process of cement production so that the cement production has the advantages of high efficiency and high quality to meet environmental requirements. The new dry cement production is modern cement production method with large-scale and automated features, and it also has the modern cement production technology and the corresponding modern management.
When the conventional wet and dry process rotary kiln produces cement clinker, the preheating of raw material is completed in the kiln. As the firing device, the rotary can provide the cross-sectional temperature distribution uniform temperature field and can ensure that the materials have residence time at high temperatures sufficient, which can still meet the requirements. However, they are not ideal as the heat and mass transfer equipment. The are not suitable for preheated decomposition process which needs large quantity of heat. However, the suspension preheater and the precalcining technology fundamentally change the heat transfer condition of the preheating and the decomposition process of the raw material so that the heat transfer is very fast and the efficiency is very high.

The Analytical Method of Sand Making Mechanism

The cage sand making machine is mainly used for the soft or semi-soft clay, which is used to manufacture the fine powder for brickmaking or cement.  The main sand making parts of the cage type sand making machine include two oppositely rotating cages. Each cage has a steel plate fixed on the hub. There are two to three laps of the steel bars which are perpendicular to the steel plate. The two wheel hubs are installed on the horizontal drive shaft with the key and the platen at the ends of shaft. The centerlines of the two axes are in a straight line. Each shaft is equipped with the V-belt wheel. The motor drives the rotation of the cages in the same direction through the belt drive. The specifications of the cage sand making machine are presented by the diameter and the width of the outermost circle of the cage.
The cage sand making machine uses the knock-on effect of the rotary steel rod and the materials for sand making. The materials from the hopper enter two relatively rotary cages. The materials first fall to the innermost circle of steel bars and suffer from the fierce impact of the steel bars for sand making. With the centrifugal force, the materials are thrown to the next round of the steel bars. When the materials fall on the second lap of the steel bars, the above sand making process will be continued. However, the strike direction of materials is opposite to the previous circle.
The materials after sand making should be sieved. The screen of 0.5 mm or 1.0 mm is generally used. In the production, the fineness and the back flow of the materials can be adjusted by controlling the feeding amount. If you do not need the very fine powder, the larger cage can be fixed. The cage sand making machine can also be used for crushing the mud cake in the mixed mud, you need only turn one cage at this time. In addition, you should timely clear the excess material bonding on the machine parts. The refractory plant generally selects the 1000 × 290 mm cage sand making machine. The moisture of the materials for sand making should not be more than 6% to 8% and the feeding particle size should not be larger than 30 mm. When the yield is relatively high, you can use the 1350 × 300 mm cage sand making machine.
The production capacity of the cage sand making machine is related to the speed of the cage, diameter, width, space of steel bars, hardness of the materials and other factors.

Application of Crushing Equipment in Iron Ore Plant

In recent years, the cone crusher uses the hydraulic technology and large rolling bearings to increase the crushing strength and vibration strength. The spindle is fixed. The eccentric sleeve is shifted up directly drive the cone to eliminate the gap between the eccentric sleeve and the straight set so that the crushing work is strengthened. The demarcated size of the discharge opening can reach 70% or 80%.
After entering the 21st century, a new generation of HP series hydraulic cone crusher uses the slow cone, large eccentricity, high shimmy, large crushing force, the surrounding multi-cylinder, hydraulic locking and spherical bush bearing structure. There are six types of the crushing chambers of the installation of the crusher from the coarse crushing to fine crushing. The fine crushing cavity uses the material layer crushing principle. The ore particles in the crushing cavity are squeezed and they suffer from strong grinding action. Therefore, a lot of fine powder is produced. The machine can reduce the maximum feed size. At the same time, it greatly changes the composition of feed size.
 The new type of jaw breaker with moving jaw is produced by Henan Hongxing Mining Machinery. The motor drives the eccentric shaft through the V-belt. The rotation of the eccentric is driven to the movable jaw by the side plate so that the moving jaw can periodically swing. The materials that fall into the crushing chamber are crushed by squeezing, arm crack and bending. The materials after crushing are discharged through the discharge opening. The outer moving jaw is located outside of the crushing chamber, and its periodic motion helps feed and discharge. The moving jaw and the connecting rod is separated so that the rod movement no longer constrains the motion characteristics of the moving jaw. The trajectory of the moving jaw can be adjusted only by changing the institutional parameters to get the ideal motion characteristics for moving jaw. The horizontal direction of the moving jaw itinerary becomes large and the vertical direction of the stroke is small. The crushing chamber is in inclined state to reduce the height of the equipment.
With the sustained and rapid development of the national economy, the demand for mineral resources and energy becomes more and more. As a result, the crushing equipment is more and more widely used in the iron ore plant. How to improve the level of rational utilization of mineral resources, save energy and reduce consumption is the priority.

How to Effectively Reduce Impact of Sand Production

In the construction projects, a lot of mining resources are exploited to beused for processing concrete aggregate. However, in the process of mining and processing, it is easy to damage the natural environment, human production and living environment, including the destruction of security and stability of the hillsides body, destruction of the vegetation, the dust generated in the screening process, the noise and the wastewater.
The environmental protection is China's basic national policy. For the artificial aggregate production required by engineering construction, we should take full account of the technical solutions that are conducive to the environmental protection. We should make full use of the useful material of the waste slag produced in the engineering excavation to process concrete aggregate and try to reduce the mining range of the mountain farm materials so that the resource development and the natural environment tend to be harmony and unified. In terms of the planning and design of the field of mining materials, we should select the mining area with large useful reserves but small area. In addition, we should put forward the specific requirements and supporting methods to deal with the slope stability of the mining areas to prevent the destabilization of the mountain caused by improper mining design. The waste slag generated in the mining process should be stocked in a proper place with good drainage and protection design.
In the crushing and screening process of the aggregate, in order to ensure the quality of the finished aggregate and reduce processing costs, we should select reasonable ways according to the different characteristics and scales of the raw materials for processing. The crushing of the aggregate will produce a lot of dust and noise. The vibrating screen and vibrating feeder drive the exciter for straight line or circular motion. The beating of the material on the screen surface and the mechanical movement of the screening machine will produce noise. Therefore, we must control and reduce the production of pollution on the environment.
First, we should select crusher with perfect performance and low center of gravity to control the noise to a minimum from the source control.
Second, in terms of the sieve, we should try to choose the polyurethane screen with good damping effect.
Third, we should increase the concept of environmental protection and popularize the knowledge of environmental protection.

Welding Equipment and Maintenance Methods of Crusher

Before welding the crushing equipment, you should pay attention to the following tips.
First, you should thoroughly clean the parts to be welded before welding.
Second, the effect of hot welding is better than the effect of cold welding. Therefore, when the major parts are welded, you may try to use the hot welding. You can heat the weldment to 100 ° C to 700° C in advance.
Third, in the conditional case, you should use downhand welding which will be good for the quality of the weld and is conducive to the operation.
Forth, electrode diameter and current size of the welding rod should be selected depending on the thickness of the weldment, the surrounding temperature and welding location. The model of the welding rod should be selected according to the materials of the welment and related technologies.
The most common method of the weld is the vibrating surfacing and carbide hardfacing method. The practice has proved that using the high current for welding can improve the quality of welding and speed the welding. But the current should not be too high. Sometimes, low current is also be required. The overcurrent will cause the overheating of the welding rod core. The   covered electrode will be dropped early, which will increase the spatter and burning and reduce the stability of the arc so that the welding becomes difficult. At the same time, both sides of welding will be undercut. The roots will be too thin and burn easily. For the alloy steel, if the metal structure is overheating, the metal of the weld zone is perishable and the mechanical strength is reduced. If the current is too small, the penetration depth will be not enough. It is also easily to lead to impermeable weld and bad melting. At the same time, due to the small heat of the arc, the condensation of the melt injection is rapid, which will form the weld central residue and stomata.
When the impact crusher is required, you should be strict with the implementation of the operation law of the equipment, maintenance procedures and planned maintenance system to ensure the maintenance quality. Any sloppy thinking will bring loss and impact of different level. The contact of mating surfaces of the journal and the bearing is poor will cause uneven load distribution of unit area and an increase of additional load to accelerate the wear parts. Therefore, we must conscientiously implement the maintenance of equipment, really do good job in the equipment use, care and maintenance, inspect and repair the crusher in a timely manner in order to reduce the wear and tear of parts and extend the service life of the machine.

Notes for Overhaul in Each Stage of Cone Crusher

The overhaul of the cone crusher can be divided into minor overhaul, mediumoverhaul and heavy overhaul. Under normal circumstances, the overhaul should be proceeded according to the pre-preparation equipment and the date formulated by the scheduling cycle chart. You must consider the order of the minor overhaul, medium overhaul and the heavy overhaul, interval, overhaul period and service life of the various parts and components when you draw up the maintenance cycle chart. You should carefully keep technical information record  of inspection, measurement, adjustment and repair, replacement, and maintenance projects of various types of maintenance. You should also predict the next maintenance project and amount of work so that the maintenance work of the whole equipment can work normally. You must proceed the commissioning and technical determination of the equipment after the heavy overhaul and complete acceptance certificate of equipment overhaul work.

Competition in Mining Machinery Industry Increases

In today’s society, the economy develops very quickly which drives the development of various of industries. The mining machinery industry is not an exception. With the rapid development of the mining machinery, many enterprises have produced a lot of crushing and grinding equipment, such as jaw crusher and ball mill. At the same time, the competition in mining machinery industry greatly increases. In this article, the experts of Henan Hongxing Mining Machinery will carefully analysize the competition of the mining machinery industry.
First, worldwide M & A activity is increasing. Beyond the Chinese market, the world's top ten manufacturers of mining machinery account for about 85% of the market share. The control of the whole industry is concentrated in a small numbers of enterprises.
Second, the world's mining machinery market growth is accelerating. The demand generated by China's huge infrastructure construction is a major contributing factor. From 2008 to 2009, the Chinese market surpassed the North American market and the Chinese market has become the largest market which sales the largest numbers of mining machineries. In 2010, the proportion of the Chinese machinery total may account for 50% of the total world mining machinery production.
Third, the world's mining machinery rental market is actively developed. The proportion of the leasing companies in the UK accounting for the total sales of the British mining machinery sales is 75%, and 60% in North America, 50% and 40% respectively in France and Germany. China has not yet reached this level. However, the domestic level is likely to reach this level after a few years.
Fourth, the world's mining machinery production and demand are transfering to China. The major manufacturers have set up factories in China, and the main parts makers are also attracted to China. A major obstacle for the development of mining machinery is the inadequate supply of high-quality components. Now the situation has began to change. Since the ownership of mining machinery products is sufficient to complete the project now, the global mining machinery market in emerging vitality keeps in a stable and conservative state. From the future development trend of the world mining machinery industry, the comprehensive ability of manufacturers is increasingly important. These capabilities include the support of the purchase for the customers, because a lot of machine sales will be achieved through loans.
Fifth, for the domestic mining machinery market, the increasing expansion of the production and the influx of foreign enterprises both have increased the uncertainties of the future development of the industry. Therefore, how to fairly avoid market risks and vicious competition are the topics which should not be neglected for the enterprises in the rapid development in the future.

Trend of Superfine Crushing Equipment and Technology

Modern engineering technology will need more and more purity ultrafine powder, so ultra-fine crushing technology will play an increasingly important role in high-tech research and development. High-purity ultrafine powder can be made through chemical synthesis, but the cost is too high. Therefore, the chemical synthesis has not been used in industrial production. The primary means to obtain the ultrafine powder remains mechanical crushing method. The superfine crushing and classification technology of the machinery for the production of ultrafine powders becomes increasingly difficult. The research depth is endless. The ultra-fine crushing technology is the comprehension of multifaceted technologies and its development depends on the advancement of the related technologies, such as the process of the hard and high-toughness wear-resistant components, high-speed bearings, and the distributed measurement of the submicron particle size. Therefore, the future development and research should be oriented the following aspects.
First, develop the Fine supporting grading equipment for the superfine crushing equipment and other ancillary equipments. The closed-loop process combined with the superfine crushing and grading equipment can improve the production efficiency, reduce energy consumption and ensure that qualified products granularity. It can be said the grading equipment with large capacityand high precision is the key to the development of ultra-fine crushing technology. We should develop the equipment mainly from the view of the entire process system and improve the supporting grading equipment, products transportation equipment and other auxiliary process equipments on the basis of the existing crushing equipment. 
Second, we should improve efficiency and reduce the energy consumption tocontinuously improve the superfine crushing equipment. The key of the superfine crushing equipment superfine crushing technology is the equipment. Therefore, the first step we should do is to develop the new type of ultra-fine crushing equipment, such as Japan's MICRO ultrafine ball mill. This kind of equipment uses the powerful impact of high pressure jet to make the materials dissociated and burst along the layer or defects to achieve the purpose of the ultra-fine flakes. Therefore, this type of equipment is suitable for mica and kaolin.  It is characterized by low energy consumption, low noise, large capacity and small footprint. 
Third, we should achieve the integration of the research and development ofultra-fine crushing and grading equipment. The ultrafine crushing and grading equipment must be adapted to the characteristics of the specific material and the indicators of the products. The specification model is diversified.
Forth, we should development the multi-function superfine crushing equipment and surface modified equipment. For example, we can combine the ultra-fine crushing process with the drying process.

Transformation for Increasing Capacity of Cone Crusher

Ore crushing is the first process for the sintering alumina production, which is the crushing and homogenization of ore and provides original ore with certain fineness for grinding the original pulp and raw slurry. The crusher is the core equipment of the ore crushing system and it is also the major factor restricting the capacity of the crushing system. We mainly transform the cone crushers and improve the screening efficiency to improve the capacity and reduce the particle size of the entire crushing system.
The cone crusher mainly consists of frame, transmission shaft, eccentric sleeve, spherical bearing, crushing cone, adjustment device, adjustment sets and feed opening. When the cone crusher is at work, the motor drives the rotation of the eccentric sleeve by the horizontal axis and a pair of bevel gears. The cone axis of the crusher does rotary pendulum movement with the action of the eccentric sleeve so that the ore in crushing cavity is constantly squeezed, broken and impacted.  The capacity and particle size of the crusher is determined by the size of the gap of the discharge opening. In addition, the gap of discharge opening of the medium crusher and fine crusher must do match with each other so that the capacity of the whole crushing system will be the largest.
The cavity type of the crusher is inverted cone. The structural design of this cavity can not cohere with the requirements of the through capacity of sections along the crushing chamber height. In the parallel, the thickness of the material is relative to the discharge opening and the discharge opening is a key factor to determine the capacity of the crusher.  In fact, the moving trajectory is very complex of the material in the crushing cavity.
After the comprehensive analysis, we find that there are three aspects to impact the capacity and quality of the crushing machine. First, the length of the parallel crushing mine area and the size of the discharge opening can affect the capacity of the crushers. Second, the size of the nip angle and the crushing chamber can affect the production capacity. Third, the production capacity of the crusher is affected by the frequency of swing.  
 We can take the following measures to transform the crushers to increase the production capacity. We can make full use of the characteristics of the nip angle and the length of parallel area to increase the crushing chamber and reduce the nip angle. The cone crusher after transformation has increased the production capacity and reduce the costs.

Introduction to Practical Improvement of Cone Crusher

As a famous crushing and screening manufacturer in the industry, Henan Hongxing Mining Machinery has improved the hydraulic gyratory crusher and spring cone crusher according to the shortcomings. The crushing efficiency has been improved so that the operating rate of the crusher can be guaranteed more than 80% and the effect is very obvious.
First, Hongxing improve the crushing equipment from the aspect of base material.
The cement mortar watering is generally used in the base of the cone crusher. Due to the strong impact loads, the base seriously sinks, which cause the reduction of the production of the crusher. If we still use the cement mortar watering, it will affect the production of the processing workshop. Therefore, we can use new materials such as epoxy resin as the base of watering material of cone crusher. The production practice shows its strength, stiffness, and other indicators can meet the requirement to obtain the desired effect.
The epoxy resin with the linear structure can give the polymerization reaction with the curing agent to form high-strength polymer with the network structure. The compressive strength is 3 times of the concrete.
After the demolition of the over machine, the overall base remains intact. At the contacting parts between the active base and the cement base, you can use the air pick to chisel average about 30 ~ 40mm high.    Install the active base to the required height for horizontal alignment. In addition, you should fasten the screws of the active base. Use the oxygen and acetylene flame to dry the chiseled parts of the base.   The irrigation materials include epoxy resins, ethylenediamine, dibutyl phthalate wollastonite. When the curing time reaches 12 hours, the equipment installation can be completed.  After the 48 hours’ curing time, re-fasten the screws.
Second, we will explore the improvement of the spring system.  The spring system of the cone crusher can ensure the crushing force in normal working of the crusher and it is also the safety device. In terms of the problem of the insufficient pressure of the spring, we can re-adjust the spring pressure and increase the thickness of the nut. 
Third, we should improve the filler material. We can use the cement mortar to replace the zinc alloy. The cement mortar can save time and effort, and the cost is very low. In the above ways, the improvements of the cone crusher will greatly improve the starting rate of the machine.
