High efficiency grinding apparatus

DETAILED DESCRIPTION Accordingly, the present inventive grinding apparatus provides a structure and method intended to overcome many of the shortcomings and attendant disadvantages of known pulverizing, grinding and comminuting apparatus that share problems considered unavoidable within the industry, some of which have been discussed herein above.
The present invention, however, surmounts many of these problems with a radical new structure that accommodates novel placement of selected screening elements to enhance and optimize pulverizing, grinding and comminuting efficiency.
The apparatus constructed according to the present invention comprises at least one product inlet (feeder) section, one or more grinding/pulverizing chambers (sections) and one or more product discharge sections (ports) to accommodate collection of the comminuted product(s).
A rotating shaft having a plurality of beaters/hammers coupled radially and circumferentially spaced thereto extends axially through the product grinding chamber(s) such that the rotating shaft and the grinding chamber(s) share a common central axis.
The one or more grinding/pulverizing sections include one or more arcuate screening elements coupled to the inner surface of a cylindrical housing such that the radial distance between the axis of the rotating shaft and the inner surface of the arcuate screening elements is identical with the radial distance between the axis of the rotating shaft and the grinding/comminuting end surfaces of the beaters/hammers.
The unique structural placement of the screening elements provides additional grinding action as the beaters/hammers rotate past the screening elements such that the aforesaid screening elements participate in the comminuting process rather than being limited substantially to filtering of particular constituent particle sizes.
A series of precisely sized ribs (back bars) is optionally attached to the selected portions of the inner surface of the pulverizing section(s) cylinder housing to act as a mounting structure for the selected screening element(s)
