Abstract
A materials grinding and processing machine includes a sizing concave having a sizing screen contained therein. Ordinarily, the sizing concave is pivotally connected adjacent its upper end to the frame of the materials processing machine. To replace the sizing screen, a temporary pivotal connection is made between the lower end of the sizing concave and the frame. The upper end of the sizing concave is permitted to swing away from the frame to provide access to the sizing screen from above. A hydraulic cylinder, coupled between the frame and the sizing concave, can be selectively attached at different points on the sizing concave to move the sizing concave and improve access, from above, to the sizing screen.
