The jaw crusher is a kind of crushing machine for coarse crushing or common crushing material with different hardness by the extrusion and bending effect of jaw slabs. The gravel mechanism consists of a fixed jaw and moving jaw board, when the two jaw slabs closed, material is broken, while when the two jaw plates opened, material less than discharge gate will discharge through the bottom discharge part. The crushing movement is intermittent. This crusher is widely used in mineral processing, building materials, silicate and ceramic industries and other industries with its simple structure, reliable operation and suitable for crushing hard material, etc.

    The hammer crusher has characteristics of big crushing ratio, discharge of granularity, low energy consumption, less over crushing and other advantages. But as a result of wear faster of hammer head, broken application is limited in the hard material; in addition, because of cage bar is afraid of congestion, it should not been used to crush big humidity and clayey material. This crusher is usually used to crushing limestone, shale, coal, gypsum, chalk and other hard material following brittle material.

    Compared with the hammer crusher, impact crusher is crushing machine using of the high speed impact and counterattack plate rebound effect of plate hammer to make the material bearing repeated impact. Plate hammer solid loading in the high speed rotating rotor, and along the crushing cavity with different angle arrangement. Counterattack crusher has a larger crushing ratio, and can more fully use high-speed impact energy of the whole rotor. But due to the easy wearing of plate hammer, it’s crushing applications is also restricted in hard material, so it is usually used for coarse crushing, common crushing or fine crushing limestone, coal, calcium carbide, quartz, dolomite, pyrites, etc.
