An orifice plate with an outer grinding section and an inner grinding section is disclosed. The outer grinding section is the main grinding section leading to the main material collection stream, and an additional grinding section is present in the inner section of the orifice plate to remove useable material from material swept toward the center of the plate by the action of a rotating knife assembly on the plate. The useable material obtained at the inner section is also led to the main material collection stream.
