Jaw crusher is mainly used as coarse crusher and medium crusher in mining, building materials, infrastructure and other departments. According to the width of the inlet, it is divided into three types: large, medium and small. The width of the inlet is greater than 600MM is a large machine, the width of the inlet is 300-600MM is a medium-sized machine, and the width of the inlet is less than 300MM is a small. machine. The jaw crusher is simple in structure, easy to manufacture and reliable in operation.
The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (fixed jaw), the vertical (or slightly inclined at the upper end) is fixed on the front wall of the machine body, and the other is the movable jaw plate (moving jaw), position Inclined to form a crushing cavity (working cavity) with the upper and lower sides and the fixed jaw plate. The movable jaws make periodic reciprocating movements against the fixed jaws, sometimes separating and sometimes approaching. When separated, the material enters the crushing cavity, and the finished product is discharged from the lower part; when approaching, the material installed between the two jaws is squeezed, bent, and split to break.
