Abstract
Flutes or channels are provided at the ramped entryways of an orifice plate of a grinding machine head. Ramped entryways lead from the grinding surface of the orifice plate to one or more hard material collection passages located toward the center of the plate. Providing flutes at the ramped entryway, rather than a smooth surface, helps control the flow of hard material into the hard material collection passages by creating friction to maintain hard materials in the entryway area once collected there, and by encouraging flow of hard materials toward the collection passage.
