Jaw crushers are mainly used as primary crushers and secondary crushers in mining, building materials, infrastructure and other departments. According to the width of the inlet is divided into large, medium and small three kinds, the width of the inlet is greater than 600mm for the large machine, the width of the inlet is 300-600mm for the medium-sized machine, and the width of the inlet is less than 300mm for the small machine. The jaw crusher has a simple structure, easy manufacturing and reliable work.
The working part of the jaw crusher is two jaw plates, one is a fixed jaw plate (fixed jaw), which is vertically (or slightly cambered at the upper end) fixed on the front wall of the machine body, and the other is a movable jaw plate (moving jaw), which is inclined to form a large crushing cavity (working cavity) with a fixed jaw plate. The movable jaw plate makes periodic reciprocating motion against the fixed jaw plate, sometimes separated, sometimes closer. When separated, the material enters the crushing chamber and the finished product is discharged from the lower part; When it is close, the material installed between the two jaw plates is crushed, bent and crushed by the action of splitting.
Jaw crusher can be divided into simple swing jaw crusher (simple swing jaw crusher) according to the different swing modes of the movable jaw plate. There are three types of complex oscillating jaw crusher (compound swing jaw crusher) and comprehensive oscillating jaw crusher.
