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.
Claims8
A mono roll grinding mill (MRGM) comprising:
- a. a shell comprising a substantially cylindrical structure having an inner surface which defines a chamber wherein the shell rotates about a horizontal longitudinal center shell axis;
- b. a single roller located within the shell;
- c. the roller comprising a substantially cylindrical outer surface;
- d. wherein the shell is mounted to a driving apparatus to rotate about the longitudinal center shell axis offset from and parallel to a longitudinal center roller axis;
- e. wherein the MRGM is configured to have material inserted into the chamber and comminuted between the shell and the roller;
- and
- f. the roller independent of an external pressure system configured to increase pressure between the roller and the shell.
