Abstract
A material sorter apparatus includes a drum mounted for rotation and a coaxial trommel mounted within the drum. Raw material is applied to the trommel. Rotational movement of the drum imparts expulsion of large material in the raw material from the trommel out of the device. The rotational movement of the drum imparts filtration of the raw material through the trommel into the drum as fine material. The drum is fluid impervious and is formed with an inwardly-directed lip. The trommel and drum are angled with respect to a horizontal. A wash is directed into the drum to wash the raw and fine material in the trommel and drum. The drum is mounted for pivotal movement to a stand.
Claims20
A device comprising:
- a drum;
- a coaxial trommel mounted within the drum, the trommel having an open front, an opposed closed back, and an axis of rotation extending upwardly from the back to the front;
- and
- raw material applied to the trommel;
- wherein movement of the drum imparts expulsion of large material in the raw material from the trommel out of the front of the trommel;
- and
- movement of the drum imparts filtration of the raw material through the trommel into the drum as fine material;
- and wherein the back of the trommel is rigidly fixed to the back of the drum;
- and wherein the diameter of the drum is greater than the depth of the drum.
A device comprising:
- a drum mounted for rotation;
- a trommel carrying raw material, the trommel having an open front, an opposed closed back, and an axis of rotation extending upwardly from the back to the front, and the trommel mounted to the drum for rotation with the drum;
- rotation of the trommel engenders relative motion between the trommel and the raw material in the trommel;
- relative motion between the trommel and the raw material in the trommel filters fine material from the raw material into the drum;
- and
- rotation of the drum pans dense material from the fine material in the drum;
- and wherein the back of the trommel is rigidly fixed to the back of the drum;
- and wherein the diameter of the drum is greater than the depth of the drum.
A device comprising:
- a drum mounted for rotation, the drum including a cylindrical sidewall extending between an endwall and an open front;
- an inwardly-directed lip is formed in the open front of the drum;
- a trommel mounted to the drum for rotation, the trommel including a cylindrical sidewall extending between an endwall of the trommel and an open front of the trommel, and an axis of rotation extending upwardly from the endwall of the trommel to the open front of the trommel;
- the trommel is fixed to the endwall of the drum;
- and
- the open front of the trommel extends beyond the lip of the drum;
- and wherein the back of the trommel is rigidly fixed to the back of the drum;
- and wherein the diameter of the drum is greater than the depth of the drum.
