Conjugate anvil hammer mill

Abstract

A crushing mill with an internal ring inside an external ring is disclosed. In some embodiments, the inner ring has protrusions that fit within pockets in the outer ring such that as the rings rotate rock or other materials may be crushed between the protrusions and pockets of the inner and outer rings, respectively. In some embodiments, the inner and outer rings each have surface protrusions such that rock or other materials may be crushed between the inner and outer rings as they rotate. In some embodiments, the inner ring has a circumferential ridge that fits within a circumferential groove of the outer ring such that rock or other materials may be crushed between the rings. In some embodiments the rings operate at differential speeds with respect to each other to induce shear forces on the material to be crushed.
