Self-Cleaning Hump Magnet

Self-Cleaning Hump Magnet

Self-cleaning hump magnet remove unwanted tramp metal from gravity or pneumatically conveyed products. They are always used in remote areas of customer's facility or place where requires frequent cleaning of the iron magnets.

Self-cleaning hump magnet consists of two plate magnets, stainless steel housing and one iron self-unloading system. Two plate magnets are arranged on both sides of the V-shaped chute to ensure that the magnetic surface and material are in full contact to enhance the iron removal effect. Material is forced to change directions and then pass over a second magnet for additional ferrous removal. Self-cleaning hump magnet apply the PLC module to controll self-unloading system, and need to stop the production line during unloading.

Characteristics and advantages

  • Automatic cleaning (discontinuous)
  • Compact structure and small volume can save installation space
  • All mild or stainless steel construction, dust-tight enclosure
  • Suitable for a variety of special environments (corrosive, food raw materials, etc.)
  • Ceramic magnet circuits or rare earth magnetic circuitsis are suitable for tramp metal or fine metal
  • Discharging iron outside the flow channel can avoid secondary pollution

Optional configuration

  • Carbon steel or stainless steel are optional for housing
  • A variety of magnetic circuit and temperature tolerance criteria are available
  • Equip different adaptors for inlet and outlet according to site requirements
  • Optional number and type of magnetic poles
  • Optional inspection window to observe the adsorption of iron


Self-cleaning hump magnets are mainly used for powder streams in free-fall or chute applications. The chute angle may not exceed 45° from the vertical.

Material handling

Feed, peanuts, grains, sawdust, fiberglass, plastic, rubber and other materials, etc.
