Application of  jaw crusher

 

     The Dongmeng gravel jaw crusher is used in primary crushing for gravel production .It processes various kinds of ore with compression strength not more than 320mp. It has been widely applied in area of is widely used in mining, quarry, metallurgy, building, highway, railway, construction wastes processing, water conservancy and cement production, etc. .The jaw crusher is divided into the coarse jaw crusher and the fine jaw crusher, i.e. PE series and PEX series.

 

Characteristics and Advantage of  jaw crusher

 

1.High reduction ratio and even final particles
2.Simple structure and easy to be maintained

3. Easy replacement of wearing and spare parts
4.Reliable operation and long service life 
5Convenient maintenance and low maintainance charges

6.Wide ranges of products series

 

Working principle of  jaw crusher

 

     The motor drives the eccentric shaft to rotate by the V-belt & the slot wheel, then the movable jaw moves back and forth to break the materials in the crushing cavity which is composed of fixed jaw plate & movable jaw plate and side guard plate. When the movable jaw rises, the angle between the fixed jaw and movable jaw gets larger, and the materials can be broken to reach the crushing target. When the movable jaw is moving down, the angle between the fixed jaw and movable jaw becomes smaller .the end products slide from the discharge opening at the bottom of the gravel jaw crusher
