Permanent magnetic drum is also called magnetic pulley,apparatus magnetic equipment for magnetite ore, mainly used for pre concentration before fine crushing or grinding to remove the gangue, deads and tailings, and the tailings out rate is about 10%.
The materials are uniformly fed to the belt. When materials go through the permanent magnetic drum, the non-magnetic and low-magnetic particles will leave the belt surface because of the centrifugal force and gravitation. Meanwhile, strong-magnetic particles are absorbed to the belt by magnetic force and then fall into the magnetic trough when the belt leaving the magnetic pulley.
1、It is applied in lean iron roughing after the roughing crushing or middling crushingto remove deads, improve grade, and reduce the load of the next procedure.
2、For not fully reductive raw ore of hematite reduction.
3、For the ceramic industry to remove iron and improve the quality of ceramic products.
4、For other industries needing to remove iron, such as Burning coal, sand casting, refractory material, etc.
