Drawer magnets have been designed for use when a low overall height and a large cross-section are required. Iron particles are attracted to the bar magnets by magnetic fields. The product flow slows down as it passes the first stack of bar magnets, which is slightly raised. The drawer magnet is used to screen out any ferrous material from granular and floury products. To remove any screened objects or to clean the magnetic grill, the drawer can be taken out and the bar magnets removed from the magnetic grill.
