Self-Clean Chute Magnets

MPI’s Self-Clean Chute Magnets are designed to remove medium to large size ferrous tramp iron contaminant from high-volume product streams in gravity-fed vertical chutes, such as grain, chemicals, food and powders. Magnetic Chutes are ideal for use with heavy product flows that would either bridge or choke if filtered through magnetic grates. Magnetic Chutes help protect equipment such as milling, processing and packaging machinery as well as improve product quality.

How the Self-Clean Chute Magnets Works:

The product stream flows between two large permanent magnets located on either side of the chute. A center diverter directs the product flow towards the two magnetic faces, which are stepped to minimize tramp metal “wash-off”. Tramp metal contaminants are “pulled” from the product stream and attach to either magnetic face. The pneumatically operated cleaning shell safely removes the tramp metal from the product stream to a disposal area outside the chute.
