ABSTRACT:
The invention involves equipment comprising what may be referred to as a cutting head cylinder or unit provided with discharge passages and adjacent cutting edges and an improved impeller rotatable in the unit for directing a product or material introduced into the head tangentially against the cutting edges for comminuting or reducing the size of the product for flow outwardly through the passages. More particularly, the impeller structure embodies improved principles of design and construction and method of its operation whereby the product is presented substantially uniformly or evenly to the cutting edges and over the inside surface throughout the length of the cutting head or cylinder in order to substantially alleviate any concentration of the product in any localized areas within the confines of the head. Such presentation or dispersion of the product serves to maintain or preserve the inherent quality of the resultant comminuted product and appreciably reduces friction and the noise level during the comminuting process by utilizing the improved impeller structure.
