An improved magnetic separator suitable for processing food grain

An improved magnetic separator suitable for processing food grain: An improved rotary magnetic separator includes a freely rotating spur wheel (6) on its horizontal axis and also a freely rotating magnetic drum (5) on it axis just below the spur wheel. A non-magnetic inclined guide plate (3) separates spur wheel and rotary magnetic drum and also the guide plate encloses magnetic drum. Grain under process of cleaning is allowed to fall on spur wheel, consequently spur wheel rotates due to the impact of falling grain and it also rotates the magnetic drum underneath which is connected to spur wheel by a flat belt (12) outside the housing. Falling grain after passing through spur wheel glides over guide plate (3) at a retarded speed and finally falls off through the outlet (8) placed just vertically down. Iron particles while gliding over guide plate gets attracted to magnetic field created by the rotating magnetic drum (5) and hence dragged horizontally to another out let (9) where attracted iron particles drop down due to diminishing magnetic field. Thus iron particles are separated from grain completely.
