Abstract
A frame of a jaw crusher comprises a front wall for receiving crushing force and side walls connected to the front wall. The frame of the jaw crusher comprises a front part and a rear part joinable to the front part, and the front part comprises the front wall, and a major part of the front wall and the front part of both side walls form a unitary piece. A jaw crusher and a crushing plant.
Claims17
A jaw crusher comprising:
- a jaw;
- an eccentric shaft configured to support the jaw;
- a frame configured to receive the eccentric shaft and to support the eccentric shaft;
- a power transmission configured to move the jaw with rotation of the eccentric shaft back and forth in a crushing direction and opposite to the crushing direction to create crushing forces with crushing movements in the crushing direction;
- wherein the frame comprises:
- a front part including a front wall and a pair of front side walls, wherein the front wall and the pair of front side walls are a unitary piece;
- and
- a rear part having an eccentric recess configured to receive the eccentric shaft, the rear part including a pair of rear side walls;
- wherein the front and rear parts are attachable to each other and detachable from each other with flange-screw joints that connect the side walls of the front part with the side walls of the rear part on both sides of the frame and which joints bear tension forces corresponding to the crushing forces,
- wherein the eccentric recess is horizontally spaced from the joints.
