Overview
Jaw crushers is used for Primary crusher and Secondary crusher for crushing all kinds of minerals and rocks.
Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds of materials of any hardness, as well as their low-cost operation and easy maintenance.
Jaw crushers are widely used not only in mines and chemical plants but in stone aggregate and limestone crushing plants.
APPLICATIONS
These crushers are widely used not only in mines and chemical plants but in stone aggregate and limestone crushing plants.
Features
Deep Crushing cavity and no dead area, which improve production capacity and output
High reduction ratio and uniform final product size
Jaw crushers employ hydraulic jacking setting system to reduce the time of jaw plates change
Reliable and safe lubrication system, convenient replacement of parts and small work load of maintenance
Large adjustment range of discharge setting to meet the various demands of users
Low noise and little dust
Light weight for easy transportation and assembly
Adopts spherical roller bearings for economized driving power and high reliability.
Achieve both“ coarse and medium” crushing and “medium and fine” crushing.
Working Principle
Jaw crushers are driven by a motor, and the moving jaw moves up and down via eccentric shaft. The angle between fixed jaw and moving jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It will become bigger when the moving jaw runs up. The moving jaw plate leaves the fixed jaw plate under the action of pole and spring, and then the end products come out from the crushing cavity. And also, Jaw crusher is used as both Primary jaw crusher and Secondary jaw crusher.The jaw crusher has many kinds of structures while their working principle are similar. This working manner of jaw crusher is hyperbolic extrusion.
