Working principle
The working part of the jaw crusher is two jaw plates: One is the fixed jaw (fixed jaw), which is vertically (or slightly inclined at the upper end) fixed on the front wall of the body; the other is the movable jaw (moving jaw), the position is inclined, and the fixed jaw forms a large and small crushing cavity (working cavity). The movable jaw plate makes periodic reciprocating motion against the fixed jaw plate, sometimes separating and sometimes approaching. When separated, the material enters the crushing cavity, and the finished product is discharged from the lower part; when it is close, the material installed between the two jaws is crushed by squeezing, bending and splitting.
Jaw crushers can be divided into simple swing jaw crushers (simple pendulum jaw crushers) according to the different swing modes of the movable jaw. There are three types of complex swing type jaw crusher (compound swing type jaw crusher) and comprehensive swing type jaw crusher.
