Introduction: Jaw crusher is a kind of machine which is mainly made of one stationary jaw plate and one movable jaw plate. It is also called multiplexing pendulum jaw crusher. This principle of this crusher is that: through the periodic reciprocating movement between the stationary jaw plate and the movable jaw plate, materials can be extruded or crushed. It is widely used for different hardness of coarse materials and small materials. It can be divided as ordinary jaw crusher and fine jaw crusher. As a kind of primary crushers, pe jaw crusher is usually used in different stones processing lines and metal mining production lines. It is widely applied in mining, metallurgy, architecture, highway, railway, water conservation, chemical industry and other industries, for different ores and big materials medium-grained crushing. Feature: 1. The movable jaw assembly uses high quality casting steel; 2. The heavy eccentric shaft adopts forging, heat treatment, annealing, crack detection etc. Processing, then it can guarantee the stability of lead plane. 3.The inner bearing uses aligning roller, double row double roller bearing which can guarantee it with higher carrying capacity. 4.Simple structure, easy operation, convenient maintenance. 5. Deep crushing cavity and without dead zone, improve the ability of feed and output. 6. Large adjustable range of discharge opening can meet the different requirements of different specifications.
