The Greenwood Permanent Magnet type CPM32 is designed primarily for fitting over carding automatic feeders and conveyors for the extraction of ferrous metals from either wet or dry materials being processed. The CPM32 (Continuous Pole Magnet) housed in rectangular aluminium is fitted with support brackets and pivot studs at each end. Two U-shaped brackets (supplied with the magnet) are secured to the side mountings of the conveyor to support the studs. Fine adjustment of the height of the magnet is achieved by using the adjustable screws located on the U-shaped brackets.
