 High capacity rock /stone crusher for quarry 

Product Introduction

High capacity stone crusher, whose reduction ratio up to 4-6 and the finished products are even, can be widely used in breaking hard, medium-hard, soft ore, such as various kinds of ore, the solvent, slag, building stones, marble,etc. compression strength does not exceed 320Pa. This machine is suitable for mines,building materials,highway,railway,water conservancy and chemical industry,etc
Jaw crusher mainly consists of main frame, movable( swing ) jaw, eccentric shaft, toggle plates etc. The electric motor passes power via V-belt pulley to the eccentric shaft to make the movable jaw moves in mesh, therefore, materials in crushing chamber can be crushed.

Working Principle

The machine’s V-belt and wheel are driven by the electric motor, then the movable jaw plate begins to move up and down by the eccentric shaft, when the movable jaw plate moves from top to bottom, the angle between fixed jaw plate and movable jaw plate becomes smaller, the material is crushed into pieces to reach the crushing target. When the movable jaw plate moves from bottom to top, the angle between fixed jaw plate and movable jaw plate becomes bigger, the crushed material is discharged from the bottom outlet of the crushing cavity.  

Structure of the Rotary Kiln

It is mainly consists of main frame, movable( swing ) jaw, eccentric shaft, toggle plates etc. The electric motor passes power via V-belt pulley to the eccentric shaft to make the movable jaw moves in mesh, therefore, materials in crushing chamber can be crushed.

Advantages and features

1)  Firm structure, stable performance, large capacity, even producing granularity.

2)  With the increase of production, our jaw crusher can greatly reduce the operating costs.

3)  Convenient maintenance and economical running expense..

4)  The large feed opening and force-feeding action from the inward and downward eccentric movement of the swing jaw mean that our jaw crusher can increase the capacity.
