Orifice plate removal system for an orifice plate of a grinding machine

摘要

An orifice plate (74) for a grinding machine is disclosed as having removal slots (118) or relief areas for ease in removal of the plate (74) from the grinding head (56). The slots (118) may be aligned with recesses (120) in the head (56) that allow easy insertion of a removal tool (122). A number of embodiments are contemplated, some of which do not require a recess in the head to be present, and others which may require a recess but do not require alignment.
