Working Principles and Structure of Roller Crusher

With the rapid socio-economic development, the social demand and the production scale of a variety of metal materials, non-metal materials, cement, building materials and other materials gradually increase. In addition, the materials need crushing increase rapidly. Due to the shortage of energy and the increase of the processing costs, the traditional crushing equipment is confronted with some of the major problems to be studied and solved. This requires that we should research and develop the new generation of crusher equipment with high-productivity and low energy consumption. The research and analysis of the dynamics characteristics of the mechanical system is the premise and key of the development of all new machinery and equipment. The roller crusher produced by Henan Hongxing Mining Machinery has showed the powerful advantages and can meet the high production requirements at the same time.
The roll crusher produced by Henan Hongxing Mining Machinery has large crushing ratio without overload protection device or large and firm foundation, which can greatly save the investment on the machine and the infrastructure. The roller crusher can achieve the selective crushing and reduce overcrushing. The unit energy consumption is low and the roll crusher has the advantages of starting stopping with load. Therefore, this article will mainly analyze the dynamic characteristics of the roller crusher.
Specifically, we should first study the relative kinematics between the working principles and the working structure of the roller crusher to establish the kinematics model for the roll crusher. We can get the motion law of the crushing cone when the materials distribute without rule in the crushing cavity according to the analysis about the empty load state and the load state of the crusher machine. Through the analysis about the working parameters of the roller crusher, we can find out the impact of the systematic parameters on the performance of the crusher. Through the analysis and calculation about the crushing force of the roller crusher, we can know the impact of the hardness of materials, change of filling rate of crushing cavity, change of discharging port on the crushing force of the crusher machine. Through the analysis about the movement mechanism of the materials and the systematic crushing process, we can establish a systematic nonlinear dynamics model to get the vibration equation of the system of the materials.
