Jaw crusher is very common in the rock stone crushing process, we mainly produce jaw crusher, impact crusher, cone crusher with various capacity model. The working principle of jaw crusher is interesting, let us talk about it first.
A rock-crushing device comprising one fixed inclined jaw and one movable inclined jaw. It is used to reduce rock to specific sizes.
A jaw crusher uses compressive force for breaking of particle. This mechanical pressure is achieve by the two jaws of the jaw 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 a fixed jaw while the other jaw, called a swing jaw, moves back and forth relative to it, mini jaw crusher by a cam or pitman mechanism, acting like a class Il lever or a nutcracker.
The volume or cavity between the two jaws is call the crushing chamber. diesel jaw crusher 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.
Jaw crushers are heavy duty machines and hence need to be robustly construct. 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, on Ni-hard (a Ni-Cr alloyed cast iron).
