Laboratory jaw crusher for small scale mining

Description

Application of jaw crusher:
1.jaw crusher is widely applied to crush high hardness, mid hardness and soft rocks and ores such as ore quartz, granite, limestone, slags, construction materials, marble and so on.
2.The maximum compression strength of materials to be crushed is **0MPA.
3.PE series is used for primary crushing, and PEX series is used for secondary crushing and fine crushing. 

Working principle:
The motor transmits power 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 moving jaw moves.So the moving 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.
