Jaw crusher is crushing machinery and metallurgy, mining, building materials, road construction and other industries widely used for crushing raw ore mined to be suitable for transport, use and grinding composite material plate hammer to break its heavy workload, work harsh conditions, and the situation is complicated by the force. Jaw is the main wear parts, consumption is enormous. How to improve the life of the jaw is the problem of producers and manufacturers are very concerned about the use of a composite plate hammer breaking performance, related to the utilization of the crusher, the economic cost of production and manufacturers. And improve the life of the board hammer jaw broken complex classification, the key is to analyze the conditions and the wear mechanism of its work, a reasonable choice of jaw plate material according to working conditions. Crusher works: After the material into the body hit the high-speed rotation of the hammer, the hammer head is hit, the bulk material was immediately broken hammer to break complex uses high-speed flying debris back plate, a second collision crushed material and the subsequent rebound flying material crushing hit each other to achieve the ultimate aim broken. Structural features: (1) using a triple back plate structure, so that the material increase in the number of strikes, hard squeeze, friction reduction, reducing wear and tear hammer and prolong the service life of wear parts. (2) the back plate and hammer gap can be easily adjusted by adjusting the bolts, effective control of the expected size. (3) PF1315 type lid equipped with a hydraulic device to make maintenance more convenient.
