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. Among them, the small counterattack liner of the counterattack breaks the anti-abrasion and impact protection of the counterattack frame.
The small counterattack liner produced by our company is added with rare alloy metals such as chromium, vanadium, boron, and molybdenum on the basis of the original manganese 13 material. The high manganese steel alloy liner produced by new materials significantly improves the product quality and compares The service life of ordinary manganese 13 products has more than doubled, greatly reducing the user's production costs.
