In a jaw crusher, the primary mechanism that breaks down material involves a pair of jaws—one fixed and the other moving. The process can be broken down into the following steps:
Feeding: Large rocks or pieces of material are fed into the top opening of the jaw crusher.
Crushing Chamber: The material falls into the V-shaped crushing chamber, situated between the two jaws.
Movement: The movable jaw is mounted on an eccentric shaft and performs a cyclical movement as it is driven by the motor. This action creates a compressive force against the stationary jaw.
Crushing Process: As the movable jaw moves forward towards the fixed jaw, the material is compressed, crushed, and reduced in size between the two jaw plates.
Discharge: Once the material is crushed to the desired size, it gravitates down through the tapered bottom of the crushing chamber and is discharged from the machine.
The efficiency of the crushing process largely depends on the design and orientation of the jaw plates, as well as the amount of material being processed and the physical properties of the feed material.
