Abstract

A crushing mill with a single roller inside a driven cylindrical shell inner surface, both with horizontal and parallel but offset axes is disclosed. In some embodiments, the roller has protrusions such that as the roller and shell rotate rock or other material may be crushed between the shell and the roller, respectively. In some embodiments, the shell and the roller each have surface protrusions such that rock or other materials may be crushed between the shell and the roller as they rotate. In some embodiments the shell and the roller operate at differential speeds with respect to each other to induce shear forces on the material to be crushed.
