MATERIALS HANDLING
a controlled feed of material flowing closer to the intense magnetic field of a stationary magnet element. Attracted metal is held to the surface of the rotating outer shell and deposited in a separate collection area under the drum. Larger diameter electro and permanent drum magnets, rotating at high speeds, handle larger volumes of ore. However, space restrictions in existing and even new ore processing plants restrict the use of drum magnets.
WORKING TOGETHER Magnetic separators commonly work alongside metal detectors, which locate non-ferrous metals such as manganese steel. Te metal detector features a coil mounted around a conveyor carrying ore. Detection of metal occurs through the disturbance of the metal detector coil’s magnetic field, with a signal sent to a remotely located control. On receiving the signal, the control either stops the conveyor and initiates an alarm or sets off a diverter gate to reject a batch of material. In many large volume mining operations, where stopping the conveyor

is not an option, a section of metal- contaminated ore diverts into a collection area, where the ore is either manually checked for metal or sent through a separate secondary system for tramp metal location and removal. Correct installation of magnetic separators and metal detectors ensures the
effective removal of tramp metal, protecting plant and saving time and money on downtime and repair.

CONVEYORS ARE THE LIFELINE TO EFFICIENT OPERATIONS
Your operation depends on conveyors to move material. When conveyors are undependable, downtime, lost production, expenses, and overall cost of operation increase.
