Westpro Jaw Crushers
Advanced Technology
Description of Operation

A jaw crusher is generally used as a primary crusher in a crushing circuit.  Product is fed into the top of the jaw crusher by an vibrating grizzly feeder.  The eccentric rotating drive shaft causes the movable jaw to oscillate crushing the aggregate against a fixed jaw.  Jaw crushers are run on belt drives driven by an electric motor or diesel engine.  Jaw crushers are used extensively throughout the aggregate and mineral processing industry.   

Westpro offers bare jaw crusher units, modular and portable jaw crusher assemblies and entire crushing plants.  Contact Westpro for your jaw crushing needs.
