Abstract
Apparatus for reducing the particle size of material subjected to the impact of the hammers of a material reducing hammer mill in which oversize material impacted by the mill hammer is prevented from getting into the stream of properly sized material by being thrown against a flow impeding member which makes such material difficult to pass a material sizing fan having spinner blades that can not effectively intercept particles that are hard, improperly reduced, and require reduction. Material flow impeding angular passages which offer resistance to flow of material that is hard and/or oversized are located to intercept the oversized material and return such material to the material reducing hammer mill for further size reduction before it is able to get into the product stream.
