The impact crusher is a kind of crushing equipment that uses the plate hammer on the high-speed rotating rotor to produce high-speed impact on the materials entering the crushing cavity, thereby crushing the materials. This equipment is widely used in various fields of production.
The regular maintenance and maintenance of the impact crusher is the key to ensuring the normal operation of the equipment. Among them, the reliability of the wearing parts determines the length of the equipment's continuous operation cycle, the customer's operating costs and the level of profit.
The vulnerable parts of the impact crusher are composed of a counterattack breaker hammer, a large counterattack liner, a small counterattack liner, a counterattack edge guard liner, a counterattack breaker square steel, and a counterattack breaker compression block.
The counterattack barrier liner produced by our company is based on the original manganese 13 material by adding rare alloy metals such as chromium, vanadium, boron, and molybdenum. The high manganese steel alloy liner produced with new materials has significantly improved the product quality. Compared with the ordinary manganese 13 product, the service life is more than doubled, which greatly reduces the user's production cost.
