  • Publication number: 20220155766
    Abstract: A dual positioned recirculating chute that would allow the operator to run the plant in either closed circuit or open circuit position. While in closed circuit position, the plant will run rock through and the chute will provide as a recirculating chute for oversized rock to travel from the recirculating conveyor back into the feeder hopper for re-crushing. The operator can then reposition the chute to the open circuit position, which will change the direction of the chute away from the feeder hopper and discharge material off the side of the plant. This can be oversized rock material to form an additional stock pile or be redirected to an off-plant conveyor. This can also allow for the removal of trash and unwanted material from the plant cycle without the need for a full plant shutdown, locking out the proper equipment, and manually removing before restarting the crushing process again.
