Abstract
A feeder breaker includes a frame, a first crusher coupled to the frame and configured to receive material, a second crusher coupled to the frame, a conveyor extending between the first crusher and the second crusher configured to convey material exiting the first crusher to the second crusher, and an output conveyor configured to receive the material exiting the second crusher. The feeder breaker is also configured to allow at least a portion of material exiting the first crusher that is below a predetermined size threshold to move to the output conveyor without passing through the second crusher.
Claims19
A feeder breaker comprising:
- a frame;
- a first crusher coupled to the frame and configured to receive a material;
- a second crusher coupled to the frame;
- a conveyor extending between the first crusher and the second crusher, the conveyor configured to convey the material exiting the first crusher to the second crusher;
- and
- an output conveyor configured to receive the material exiting the second crusher;
- wherein at least a portion of the material exiting the first crusher that is below a predetermined size threshold moves to the output conveyor without passing through the second crusher, and
- wherein the output conveyor is positioned underneath the second crusher.
A feeder breaker comprising:
- a frame having a first end, a second end opposite the first end, and a material flow direction defined between the first end and the second end;
- a conveying assembly coupled to the frame and configured to convey a material in the material flow direction;
- a first crusher coupled to the frame and configured to receive the material conveyed by the conveying assembly;
- a second crusher coupled to the frame downstream of the first crusher in the material flow direction, the second crusher is configured to receive the material conveyed by the conveying assembly;
- and
- a flow-limiting member coupled to the frame downstream of the first crusher in the material flow direction;
- wherein the flow-limiting member is configured to limit a flow of the material to the second crusher, and
- wherein the flow-limiting member is a dam coupled to the frame above a portion of the conveying assembly.
A feeder breaker comprising:
- a frame;
- a first crusher coupled to the frame, the first crusher including a first drum and a first anvil;
- a second crusher coupled to the frame, the second crusher including a second drum and a second anvil;
- and
- a conveyor extending between the first crusher and the second crusher,
- wherein the conveyor is configured to:
- (a) convey material through the first crusher, between the first drum and the first anvil,
- (b) convey the material exiting the first crusher to the second crusher, and
- (c) convey the material through the second crusher, between the second drum and the second anvil, and
- wherein at least a portion of the material exiting the first crusher that is below a predetermined size threshold bypasses the second crusher.
