ABSTRACT:
A system and method for removing a piece of tramp metal from particulate material transported by a conveyor is provided. A metal detector is used to detect tramp metal in the particulate material traveling along the conveyor. When a piece of tramp metal is detected, a redirection device positioned at the end of the conveyor is used to reject a portion of the particulate material that contains the tramp metal, by temporarily redirecting the flow of particulate material discharging from the conveyor. After the portion of particulate material containing the piece of tramp metal has been redirected by the redirection device, the system resumes normal operation.
