A small Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. Jaw crusher is widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc. The pressure resistance strength is under 200Mpa, that is, suitable for primary crush. The company Jaw crusher is designed for long life service with minimum maintenance for hard, tough, abrasive material and overload high capacity.


This jaw crusher series PF has properties of large crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, and low cost. So this kind of small jaw crusher can be widely used in mining, metallurgy, building material, highway, railway, water project, chemical industry, etc, for crushing various material with compression strength less than 320MPa.

 Designed to meet today’s - Automated Jaw Adjustment - Overload Protection System - Efficient crusher Motion maximizes product output - Reduced requirement for secondary crushing - High Production Rates - Low Operational Costs - Simplified state of the art mainframe - High Stress area welds eliminated - Cross beam fixed with freeze pins - Mass and section thickness optimized - Low head room for mobile applications

Process of Jaw Crushing Plant

The Big materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for the primary crushing. After first crushing, the material will transferred to impact crusher or cone crusher by belt conveyor for secondary crushing; the crushed materials will then transferred to vibrating screen for separating.
