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 a fixed jaw while the other jaw called a 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 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 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 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 crushers are mainly used for primary crushing equipment (coarse crushers), and are widely used for various ores and rocks in various fields such as mining, smelting, building materials, roads, railways, water conservancy, and chemical industries.
The equipment for crushing particle size includes a jaw crusher, impact crusher, cone crusher, hammer crusher, and other crushing equipment. Among them, the jaw crusher is the longest and most widely used crushing equipment. Traditional crushing equipment has many models and large output and is the first choice for mine crushing.
Working Principle
The working principle of the jaw crusher is to drive the movable jaw to carry out cyclic reciprocating motion through the eccentric shaft driven by the motor, and utilize the squeezing force and friction generated between the two jaw plates to effectively crush all kinds of ores and large pieces of materials entering into the crushing cavity, and finally the crushed materials meeting the requirements of particle size will be discharged from the bottom.
