Working principle and maintenance method of impact crusher-SBM Heavy Industry

[xuanxuan geng]

The Impact crusher is a very classic device in the large family of crushing equipment, similar to the traditional hammer crusher. Both of them crush the material by impact, but the external structure and working process are also slightly different. The main difference between the two is that the hammer of the impact crusher is the material that goes from bottom to top. And throw the material to the upper counter plate, and the hammer of the hammer crusher hits the material in the direction of the material falling. In order to ensure that the impact crusher is better operated in the gravel production line and continue the service life of the equipment, the user should carry out regular maintenance and maintenance. After the new machine is put into operation, a comprehensive inspection of the counter-attack must be carried out after the completion of each class. A full inspection of the counter-shocked motor and lubrication should be performed after each week of operation. The inspection includes the tightening of the fixed parts, the belt drive, the bearing seal, the counter-lining, the wear of the lining, etc., and comprehensive inspections are carried out in conjunction with the maintenance cycle to establish a regular maintenance and replacement system.
In the free crushing stage, when the material enters the crushing chamber, it will be immediately impacted by the high-speed hammer and the collision between the materials. At the same time, the friction between the hammer and the material and the material will cause the material in the crushing chamber. Being crushed. Due to the impact of the plate hammer on the high-speed rotating rotor, the material can obtain a high speed of movement, and then hit the counter-attack plate to further break the material, which is the rebound and crushing stage. Finally, in the grinding and crushing stage, the material which is not broken by the above two kinds of crushing and larger than the size of the discharge port is ground and crushed by the hammer which is rotated at a high speed at the discharge port.
Routine maintenance and repair usually includes: adjustment of the Impact crusher rotor and counter-backlash gap, timely replacement of wearing parts, regular inspection of the plate hammer, lining, bearing temperature and so on.
