Roll magnetic separators are used for the weakly magnetic minerals’ purification such as fine granied dried quartz, magnesite, manganese, silica, etc. Separator’s process start with vibrating feeder. In this step material’s homogeneous distribution is ensured on the roll belt. The carrier belt moves on a magnetic and non-magnetic roll. When the product moving on the conveyor belt reaches onto the magnetic roller, the non-magnetic particles are thrown by the centrifugal force and separated for the non-magnetic material shots. Magnetic materials continue to be transported on the belt by the magnetic force of the roll with the magnetic roller and the transfer to the other shot is ensured that materials are separated. Roll Magnetic Separator is used for the purification of weakly magnetic minerals with particle size between 400-25.000 microns.
