ABSTRACT:
A device for comminuting material comprising first and second mating sections. The mating sections when mated form an enclosed interior chamber with the first and second sections capable of movement relative to each other. The first mating section has a first set of a plurality of pins, which extend from a base of the first mating section and into the interior of the chamber. Similarly, the second mating section has a second set of a plurality of pins extending from a base of the second mating section and into the interior of the chamber. The pins from the first mating section interdigitate with the second set of a plurality of pins when the first and second mating sections are mated, wherein movement of the first and second mating sections relative to one another causes comminution of the material when placed in the chamber. The pins have varying cross-sectional shapes including circular, triangular, and hexagonal.
