Like similar grinders of its type, Universal meat grinders are typically constructed of several basic parts. Fresh meat is added to the hopper, which is a hollow tube, and forced down with the aid of the pusher. The elongated screw moves the meat towards the four-ended blade and the meat is forced through the round plate. The blade and plate do the grinding, reducing chunks of meat to a fine texture. The cover is placed at the back end of the hopper and keeps the blade and plate firmly in place. Meat grinder parts are numbered and designed to work with corresponding grinder models.
