The crushing cavity of jaw crusher is mainly composed of movable jaw plate and fixed jaw plate. When working, imitating two jaws
of animals, the jaw plates make periodic reciprocating motions to complete the crushing operation.
When the movable jaw plate is close to the fixed jaw plate, the material is squeezing by the two jaw plates; when the movable jaw
plate leaves, the gap between the two jaw plates becomes larger, and the material smaller than the size of the crusher discharge
port is discharged by its own weight. At the same time, the material entering the feed inlet also falls into the crushing chamber,
and the next cycle is repeated.
