Abstract
Self-correcting plate guards for installation over an orifice plate of a grinding machine are disclosed. Each plate guard has studs that fit into apertures of an orifice plate. The studs and apertures are sized so that the correct guard must be used with a particular orifice plate. Furthermore, the mounting ring that holds the orifice plate in place on the grinding machine cannot be tightened for use of the grinding machine without the plate guard being installed.
