Description

Technical Field

[0001] The utility model belongs to the technical field of jaw crushers, and in particular relates to a crushing chamber structure. Background Art

[0002] The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (fixed jaw), which is fixed vertically (or slightly tilted at the upper end) on the front wall of the machine body, and the other is the movable jaw plate (moving jaw), which is inclined and forms a crushing chamber (working chamber) with the fixed jaw plate. The movable jaw plate makes periodic reciprocating motions against the fixed jaw plate, sometimes separating and sometimes approaching. When separated, the material enters the crushing chamber and the finished product is discharged from the bottom; when approaching, the material between the two jaw plates is squeezed, bent and split to be crushed.

[0003] The body of a jaw crusher is often welded and cannot be disassembled. When the jaw crusher crushes materials through two jaw plates, the inner wall of the jaw crusher body is squeezed by the materials at the same time. Long-term use will cause the inner wall to wear and the wall thickness to become thinner, posing a safety hazard. Utility Model Content
