Abstract
An apparatus and method for removing crushing rolls from a crushing apparatus is disclosed in which arms means mounted on a movable frame supporting movable crushing rolls which move with the movable frame are utilized to remove stationary crushing rolls mounted on a stationary supporting frame to a position at which the stationary rolls may be lifted from the crushing apparatus. With the stationary and movable frames adjacent to each other, the arm means are placed in supporting engagement with the stationary crushing rolls mounted on the stationary frame. The crushing rolls mounted on the stationary frame are then released from its support so that the stationary crushing rolls are supported by the arm means. The movable frame is then moved away from the stationary frame to move the stationary crushing rolls supported by the arm means to a position at which the stationary crushing rolls may be lifted from the arm means.
