What are impact crusher wear parts?

Impact crusher is one of the widely used crushing machine.Impact crusher parts, also called impact crusher wear parts, are important parts of crusher, which need schedule replacement.Impact crusher wear parts are hammer, side guard plate, back plate, square steel, clamping blocks and other accessories which are all casted or forged by high wear-resistant materials,such as high manganese steel and high chrome.
Hammer
Hammer is made of high chromium alloy materials and the latest manufacturing technology with the unique structural design.Great Wall impact crusher processing production is finished cube, no tension and cracks,with quite good grain shape due to hammers are true high wear-resistant castings. Hammer wear to a certain extent should be timely adjusted or replaced to avoid damage fasteners and other components.
Side guard plate
Guard liner is an important vulnerability original part of impact crusher, and resisting ability decreased after aging liner wear, often resulting in accidents of liner shot down, as well as a decreasing in sealing performance producing greater dust.
The back plate
Steel back plate is generally welded by steel,equipped with the wear-resistant liner on its back surface. However,it can use counter roll or grate plates. With slit grate on back surface, fine particles content of their products is fewer, equipment production capacity can be increased, power consumption saved, but with the existence of complex structure, difficult to replace the worn surface counter, fast wear and other defects.
Square steel
Square steel is square, and can be divided into seamed and seamless.seamed square steel joints are welded together by a steel plate to square steel tube. Seamless square steel is redrawn by the seamless pipe,whose compressive strength is far greater than the pipe joints,playing the role of making material discharged from the front.
Pressed blocks
Pressed blocks are widely used in all kinds of mining machinery with good material and stable performance,which can be made according to different requirements. After the completion of the load test run, it should deal with the pressing block the necessary adjustments. Great Wall pressed blocks are stable chemical composition, heat treatment and reasonable, good wear resistance and high strength superior.
