Stone Jaw Crusher for Ore

A crusher type of high production capacity, large reduction ratio, high crush efficiency, mainly used for coarse crushing.Jaw crusher is widely used for mine, metallurgy, building material, highway, railway, water conservancy etc. section, used for dispose for coarse crushing or secondary crushing of large granularity and various ore or rock those compress strength are less than 320Mpa. 

Features of jaw crusher:

-The deep crushing cavity increases the feeding capacity and output capacity;

-High ratio of crushing, homogeneous final product size;

-Adjusting the discharge opening through gasket, more convenient, it can meet different customers’ requirenment

-Lubricate system is safe and reliable, easy to change the spare parts;

-Simple structure, easy maintenance, consumption cost is lower;

-Energy-saving, for one set saving about 15%-30%;

-Little noise and dust. 

Working principle of jaw crusher :

The motor transmits through belt,drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft.The angle between toggle plate and moving jaw plate increases when mobile jaw moving.So the mobile jaw moves towards the fixed jaw.The stuff will be crushed in this process.The angle between toggle plate and moving jaw decreases when moving jaw moves down,the moving jaw moves leaves fixed jaw by pulling rod and spring,the final crushed stuff will be discharged from the outlet.

Operating Principle of jaw crusher :

The crush cavity is composed of moving jaw and static jaw, it simulate animal’s jaw movement and complete works of material crushing. The electrical motor drives the eccentric shaft via belt connection, the vertical shaft moves up and down, when the vertical shaft moves up, the two scaleboards extend gradually to flat, force the moving jaw pushing to static jaw, the ore materials in the crush cavity broken by extruding, split strength.

When the vertical shaft moves down, the two scaleboards moves back by the strength of spring and pull rod, the discharge outlet increased to output the crushed ore. This shows the jaw crusher is crushing ore discontinuous. By contrast with other continuous crusher, the power consumption of the jaw crusher is larger, and the mechanical efficiency is lower.
