Magnetic Grate is installed or simply laid-inside of hoppers, housings, and bins to trap and hold ferrous fines,fragments,and small metal objects. please be aware these grates are built for low-abrasion materials.
It relies on the repulsive force between the same poles of the magnet to drive the other wheel for power transmission. It can realize force transmission through the air or through objects, breaking the traditional concept of gears.
