Traditional Way Designs Perfect Shaft of Crusher

This series of crusher are widely used in metallurgy, mining, chemical, cement, coal gangue, construction, sand, refractory material, ceramic and other industrial and mining enterprises, engaged in breaking and crushing the material in the operation. Used for tertiary or quaternary crushing, it is mainly suitable for crushing various ores the compressive strength of which is no more than 320MPa.
The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. It consists mainly of frame, rotor, hammers and grizzly bars and other components. The frame includes upper part and lower parts, which are welded by steel plates after cutting, the remaining parts bolted into one. High manganese steel liners are studded with inside the frame, to facilitate replacement for a new liners after worn; on the main shaft are installed several groups of the spindle distribution of the hammers, which consists of rotor with the axle of hammers and rotary table. The host drives the main shaft through the motor and V-belt driven spindle to rotate the rotor, generating the centrifugal force, and then driving all hammers stretch around. The bulks of material feed into the crushing chamber will be crushed by the hammers at a high-speed movement. The broken material requested will be passed the grizzly bars at the lower part and discharged, the unbroken rest will be left in the chamber to be crushed repeatedly by the hammers and iron plates until it can reach the requested standard. To avoid clogging, the water content of the material to be crushed not more than 5%.
Working environment of the hammer crusher is different, the operators should pay attention to the problems of hammer crusher applications, the following for analysis of hammer crusher rotor and spindle by Hxjq(specialized in manufacturing impact crusher.1. Straightening force applied is not excessive to prevent hammer crusher main shaft collapse at the hidden trouble place. When bending amount is large, straightening several times to finish. The correct number should exceed bending value of hammer crusher main shaft.
2. When straightening, to stay for some time with the straightening force, at the surface of the main shaft of hammer crusher along the axial plane with a small plumb bob gently beat in order to eliminate the internal stress to prevent straightening after deformation;
The hammer crusher main shaft as the main parts of the equipment, the process of checking and optimizing the design is complicated by using the traditional way. Technical staffs through tracking service for the manufactured products on a variety of materials, provide a reliable basis to re-design and modification for hammer crusher main shaft. Analysis results to evaluate its performance, and on this basis to design reasonable structure size, optimized main shaft of hammer crusher has higher quality and is convenient while maintaining its strength and stiffness.
