Jaw crushers are heavy duty machines and hence need to be robustly constructed. The outer 

frame is generally made of cast iron or steel. The jaws themselves are usually constructed 

from cast steel. They are fitted with replaceable liners which are made of manganese 

steel, or Ni-hard (a Ni-Cr alloyed cast iron). Jaw crushers are usually constructed in 

sections to ease the process transportation if they are to be taken underground for 

carrying out the operations. Jaw Crusher: http://www.ms-machinery.com/product/jaw-

Working Principle of Jaw Crusher: Jaw crusher uses compressive force for breaking of 

particle. This mechanical pressure is achieved by the two jaws of the crusher of which one 

is fixed while the other reciprocates. A jaw or toggle crusher consists of a set of 

vertical jaws, one jaw is kept stationary and is called as fixed jaw while the other jaw, 

called as swing jaw, moves back and forth relative to it, by a cam or pitman mechanism. 

The volume or cavity between the two jaws is called as the crushing chamber. The movement 

of the swing jaw can be quite small, since complete crushing is not performed in one 

stroke. The inertia required to crush the material is provided by a weighted flywheel that 

moves a shaft creating an eccentric motion that causes the closing of the gap.Impact
