the laboratory jaw crusher is designed for fast crushing of aggregates, ores, minerals, coal, coke, chemicals and other similar materials. It is compact and of rugged construction for general laboratory or small pilot plant operations.
Two jaws of manganese steel are provided in this laboratory jaw crusher. the moveable jaw produces two blows for every revolution, thus reducing over sizing to a minimum. A combination of forward and downward strokes with a rocking action exerts pressure on the coarser material, yet permits the finished material to pass through the jaws.

Features:

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.
5) Convenient maintenance with low cost.
6) Wide ranges of products series stone jaw crusher price.

Working Principle of Lab Jaw Crusher:

the motor of Laboratory Jaw Crusher 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. 

Specification of Lab JawCrusher:

Application:
PE series jaw 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 minerals,building materials,highway,railway,water conservancy and chemical industry,etc.
