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.
