Jaw Crushers are used to reduce the size of many different types of materials in many applications. They are designed to exceed the primary needs of customers in the mineral processing, aggregates and recycling industries. It’s consists of many parts such as an eccentric shaft, bearings, flywheels, swing jaw (pitman), fixed jaw, toggle plate, jaw dies (jaw plates), etc. A jaw crusher uses compressive force for breaking materials.
This mechanical pressure is achieved by the tow jaws dies of the crusher, one of which is stationary and other is movable. These two vertical manganese jaw dies create a V-shape crushing chamber. The electrical motor drives transmission mechanism driven swing hanging around the shaft relative to the fixed jaw do periodic reciprocating motion. The swing jaw undergoes two types of motion: one is a swing motion toward the opposite chamber side called a stationary jaw die due to the action of a toggle plate, and the second is a vertical movement due to the rotation of the eccentric. These combine motions compress and push the material through the crushing chamber at a predetermined size.
