GRIND MILL FOR DRY MILL INDUSTRY
First Claim
1. A grind plate of a grind mill comprising:
- a. a base plate having a first surface;
b a plurality of teeth aligned in a plurality of rows, each tooth extending from the first surface of the base plate, wherein each tooth comprises a tooth base width W along a radial axis of the grind plate and a tooth height H, and each tooth has a tooth height H-to-tooth base width W ratio in the range of 0.8 to 1.

Abstract
A disc mill includes an inlet configured to provide solid material for grinding to the grind plates in a smooth and constant manner. A solid ring is added around an outer circumference of the grind plates to control the grinded solid discharge rate. In some embodiments, the grind plates are configured with constant solid path way open area from row to row. The grind surface and solid pass way open area are maximized by increasing the relative tooth height compared to the tooth width. The teeth can be positioned according to a block channel configurations so as to force the solid material to pass along the grind surface of each row. A grind plate design program is used to enable conjunction of the design parameters with application variation, thereby enabling the optimum grind plate design to meeting various applications needed.
