Lift the hammer crusher everyone is familiar with the site repeatedly talked about its advantages, disadvantages, and buy, we know that the hammer crusher application is very wide, and the main components of the rotor from the spindle, disk, pin and hammer speed operation, the motor drives the rotor in the crushing cavity. Specific rotor spindle host complementary interaction, picked up we announced to everyone:
Hammer crusher material from the upper feed port into the fuselage, high-speed movement of hammer blow, impact, cutting and grinding work to be crushed. Spindle as the main operative part of hammer crusher, stone crusher key components required to meet both the high-precision, but also meet the high stiffness.
However, due to the spindle processing installation process Unevenness of spindle rotation process may be affected by the role of the eccentric force, especially in high stress parts of the gradual formation of microscopic cracks, cracks gradually expanded, it will lead to a sudden brittle fracture; there is in the rotor when working, the load acting on the rotor member are dynamic load, when the force frequency and the structure of some of the natural frequency is close to, the spindle will produce a strong resonance, resulting in the destruction or excessive deformation . Therefore, the requirements of the the broken machine spindle with high static and dynamic characteristics. The only way to meet the normal work of the hammer crusher.
