<p>PURPOSE: A jaw crusher is provided to improve the yield by closely arranging a toggle block in the receiving groove of a rear frame in order to accurate place the toggle block and constantly maintain an exit interval. CONSTITUTION: A rear frame(600) is installed between a pair of main frames(10). A toggle block is arranged in the front of the rear frame. A tension rod bracket is combined at the lower side of the toggle block. A tension rod(640) passes through the tension rod bracket. A pair of hydraulic cylinders(650) forwardly and backwardly moves the toggle block. One or more shim plates are inserted into a space between the rear frame and the toggle block. The shim plates adjust an exit interval.</p> |
