PE/PEX Series Jaw Crusher  is usually called as Jaw Crusher and is a crushing appliance that was produced relatively early. It is generally regarded as the primary breaker and is applied to various stone production lines and ore reduction production lines, due to simple construction, solidness, reliable working, easy maintenance and fewer production and construction costs. It is widely used to multiple industries, such as mines, metallurgy, building materials, highways, railways, water conservancy and chemical engineering, etc. It can process various ores with the compressive strength less than 320MPa to medium grain size all at once. this product extrudes, twists, and crushes materials in the crushing cavity by using reciprocating motion of two jaw plates, including motive jaw and fixed jaw, so as to reach the crushing purpose.
