Magnetic Humps are used where the flow of material is vertical. The material falling strikes directly on the first magnet changes direction and falls over the second magnet, ensuring clean outflow of material. Hump Magnets are Ideal for ferrous metal in gravity system. They are used in the food, chemical, plastics, textile and other industries to remove ferrous fines, as well as large pieces of tramp, iron from many types of dry particulate or clumpy, hard to flow material.
