Abstract
A jaw crusher, a crushing plant, and a method for using a crusher. A toggle plate is coupled between a pitman and a rear end of the jaw crusher with bearings at the ends of the toggle plate. A bearing holder for the bearing is present at least at one end of the toggle plate. The bearing is transferred continuously in the bearing holder to a desired location between an upper limit and a lower limit, inclusive of the upper and lower limits, with a transfer member of the bearing holder, and thus the operating angle of the toggle plate in relation to a frame of the crusher and the stroke of the crusher are changed.
Claims19
A jaw crusher comprising:
- a frame comprising side plates and a rear end arranged between the side plates;
- an eccentric supported by the side plates;
- a pitman coupled to the eccentric;
- a toggle plate coupled to the jaw crusher between the pitman and the rear end of the frame with bearings at front and rear ends of the toggle plate;
- and
- a bearing holder for the bearing at least at one of the front and rear ends of the toggle plate;
- wherein the bearing holder comprises a transfer member of the bearing with which the bearing is configured to be continuously transferable to a desired location in the bearing holder between an upper limit and a lower limit, inclusive of the upper limit and the lower limit, so that an operating angle of the toggle plate in relation to the frame of the crusher and a stroke of the crusher change.
A crushing plant comprising:
- a jaw crusher;
- a frame comprising side plates and a rear end arranged between the side plates;
- an eccentric supported by the side plates;
- a pitman coupled to the eccentric;
- a toggle plate coupled between the pitman and the rear end of the frame with bearings at front and rear ends of the toggle plate;
- and
- a bearing holder for a bearing at least at one of the front and rear ends of the toggle plate;
- the bearing holder comprising a bearing transfer member, with which the bearing is configured to be continuously transferable in the bearing holder along a trajectory to a desired location between an upper limit and a lower limit, inclusive of the upper limit and the lower limit, without dismantling the coupling of the toggle plate to the pitman and the rear end of the frame, so that an operating angle area of the toggle plate in relation to the frame of the crusher and a stroke of the crusher change.
A method for using a jaw crusher comprising:
- providing a frame comprising side plates and a rear end arranged between the side plates;
- providing an eccentric supported by the side plates;
- providing a pitman coupled to the eccentric;
- providing a toggle plate coupled to the jaw crusher between the pitman and the rear end with bearings at front and rear ends of the toggle plate;
- and
- providing a bearing holder for the bearing at least at one of the front and rear ends of the toggle plate;
- wherein the method further comprises the step of transferring the bearing continuously in the bearing holder to a desired location between an upper limit and a lower limit, inclusive of the upper limit and the lower limit, with a bearing transfer member comprised by the bearing holder, and thereby changing an operating angle of the toggle plate in relation to the frame of the crusher and a stroke of the crusher.
