I.  Application of  jaw crusher for laboratory

   1.Suitable for mining,metallurgy,smelting,building materials,water conservancy,highway,railway,

      chemical industry etc,for crushing or breaking various kinds of stones.

   2.Mainly used to crush the medium hard and hard materials,Such as limestone,phosphate rock,

      gangue,ores and so on.

II.Laboratory testing Jaw Crusher  features

   1.Firm structure, stable performance.

   2.Complete sealing design, low noise,no dust pollution.

   3.High crushing ratio and producing granularity evenly.

   4.Convenient maintenance and economical operation costs.

III.Working principle of  jaw crusher for laboratory 

    The motor drives the movable jaw plate up and down through eccentric shaft.the angle between toggle plate      and  movable jaw plate increasewhen movable jaw plate moves up,so the movable jaw plate closes up the fixed jaw plate.The stuffs will be crushed in this process.

    The angle between toggle plate and moving jaw plate decreases when mobile jaw moves down.

The mobile jaw plate moves away from the stationary jaw plate with the pull of draw rod and spring,

so the crushed stones will be discharged from the outlet.This process will repeat.

The moving jaw will crush and discharge the stuff circularly.
