How to Maintain Rotor and Spindle of Hammer Crusher

The rotor and spindle are very important components for the hammer crusher. In this article, the experts of Henan Hongxing Mining Machinery will tell some basic knowledge about the maintenance tips of the rotor and spindle of the hammer crusher.
The rotor is a high-speed rotating part of the hammer crusher, which has great impact on the mechanical properties and safe operation of the whole machine. When the rotor works, the load acting on the rotor of the hammer crusher is moving load. When the force frequency is close to some natural frequency the structure, the spindle will produce strong resonance, which will cause damage or generate excessive deformation. Therefore, the spindle of the hammer crusher should have high static and dynamic characteristics.
The materials of the hammer crusher are fed into the machine from the upper feeding port. The materials are crushed through the blow, impact, shear, abrasive action of the hammer with high speed. When the production of the hammer crusher reduces, you should check whether the gap between the rotor and sieve is too large and timely adjust the spring bolt. If the rotor and sieve plate collide with each other, you should adjust the gap between the rotor and sieve. If the rotor is not balanced, you should re-arrange the ring hammer.
In terms of the spindle of the hammer crusher, the spindle is the main force component and operative part of the hammer crusher. Therefore, both requiring high precision and high stiffness are required. The main material should be the carbon steel and alloy steel. You can also use the thermal disposal or chemical heat treatment method to improve its wear resistance and fatigue strength. The hammer crusher is used to crush the hard stone. If the stress imposed on the spindle in the process of processing installation and work is uneven, the spindle will suffer from the eccentric force to gradually form the micro-crack on the particularly high stress part, which will cause sudden brittle fracture.
Therefore, we must pay special attention to the following matters. First, the straightening force applied should not be excessive to prevent the occurrence of chipping at the crack hidden of the spindle. Second, when the bending amount is too large, you should straighten it several times. Third, the correction values should be appropriately more than the bending value.
