Jaw Stone Rock Crushing Machine Primary Crusher
 
Jaw crusher is a kind of rock crushing machine which is widely used as primary or secondary crusher. It is widely used in various industries, such as mining, road and railway construction, building construction, etc. It could crush many kinds of ores and stones with compression strength less than 320MPa, such as granite, basalt, limestone, river stone, sandstone, shale, iron ore, etc.

Working Principle:
The electromotor drives the belt and pulley to make the movable jaw move back and forth, up and down through the eccentric shaft. The raw material is squashed or splitt when movable jaw plate moves towards fixed jaw together with movable jaw. When movable jaw and movable jaw plate turn back by eccentric shaft and spring, the raw material, which is squashed or split before discharges from the bottom outlet under jaw plate. The bulk-production comes true while electromotor rotates continuously and the movable jaw crushes and discharges the raw material periodically.
