Abstract
An improvement in a bulk stacker/reclaimer of the type comprising a stacker conveyor for stacking bulk material into a pile, a reclaimer conveyor for removing bulk material from the pile and a removing means for transporting reclaimed material away from the stacker/reclaimer to a remote location. The improvement comprises a breaking means, interposed between the reclaimer conveyor and the removing means, to break apart frozen clumps of bulk material. The inflow to the breaking means is in communication with the discharge of the reclaimer conveyor and the outflow of the removing means is in communication with the breaking means.
Claims5
In a bulk material stacker/reclaimer of the type having a central tower and a stacker conveyor for stacking bulk material into a pile and a reclaimer conveyor for removing bulk material from the pile concentrically mounted on the tower for rotation, the reclaimer conveyor having a discharge end, and a removing means for transporting reclaimed material away from the stacker/reclaimer to a remote location, the improvement comprising a breaking means having an open top interposed between the reclaimer conveyor and the removing means to break apart frozen clumps of bulk material, wherein the inflow to the breaking means is in communication with the discharge end of the reclaimer conveyor and the outflow of the breaking means is in communication with the removing means and further comprising a means for directing the discharge from the reclaimer conveyor into the open top of the breaking means, wherein the directing means comprises a wall radially extending from the tower about the interior of the pile of bulk material, the wall having a top end to allow bulk material to fall over the top end of the wall into the breaking means.
In a method for stacking and reclaiming bulk material, of the type wherein bulk material is stacked in a pile by a stacker conveyor, reclaimed from the pile by a reclaimer conveyor and transported away from the pile by a removal means, the improvement comprising the step of directing material discharged from the reclaimer conveyor over a wall extending about the interior of the pile of bulk material into a breaking means which is in communication with the removal means for breaking up frozen clumps of the bulk material.
