QJ-FK-series dry permanent-magnet separator for fine ore is high-efficiency ore concentration machine newly designed by our company, which can be widely used in metallurgical mining and other sectors. The separator is characterized by its turbulent magnetic field and high separation factor, advanced structure, light weight, reliable operation and easy maintenance. It is very suitable for dry and arid regions to save water resources and reduce production cost, opening a new way for magnetite mining and utilization. The machine may be driven by diesel engine, so it can also be used in electricity-shortage regions. Apart from existing fixed types, separators with different magnetic induction intensity and adapting to different magnetic materials can also be developed according to the specific requirements of customers. The already developed product series can meet the needs of large, medium and small mines. We have industrial prototypes and provide pilot tests at customers¡¡Â request. This machine is mainly used in the following applications:
(1) For pre-separation of low-grade ores, to pre-concentrate ores, raise ore grade and reduce production cost.
(2) For re-separation of tails, to recover relatively rich tails on the dry slope of tails dam.
(3) For magnetic purification of dry fines of pyrite cinder.
(4) To effectively remove iron from non-magnetic materials with lower cost.
