The classification of the jaw crusher: In mining, building materials and infrastructure sectors, the jaw crusher is mainly used as coarse crusher and middle crusher. According to the width of the feeding mouth, it can be classified into three kinds—large, medium and small crushers. The feeding mouth width of the large jaw crusher is greater than 600MM, the medium-sized jaw crusher, 300-600MM, and the small crusher, less than 300MM.
The key components (moving jaw and fixed jaw) of the jaw crusher: the fixed jaw plate (fixed jaw) is fixed vertically (or the top is slightly extraversive) on the anterior machine body; the moving jaw plate (moving jaw) is extraversive, forming two crushing chambers (working chamber) with fixed plate (with the large one on the top and the small one beneath it). The moving jaw does cyclical reciprocating motion towards the fixed jaw, sometimes separate from it and sometimes coming close to it. When separating, materials goes into the crushing chamber, finished products come out from the lower part; when coming close, materials between two jaw plates will be crushed by extrusion, bending and splitting effects.
According to different swing methods of the moving jaw plate, the crusher can be classified into three kinds: simple swing crusher, complex swing crusher and integrated swing crusher.
There are no unified stipulations about the models of the jaw crusher. In general, manufacturers set models on their own. At present, the most common jaw crushers are PE series, which are widely used in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industry etc.
