The working Principle of iron ore jaw crusher:

 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 cecreases 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.
