29 Jul Magnetic Separator
Our company has developed a magnetic separator which can be installed directly in the head of the belt conveyor and can be configured as a separate dry magnetic separator. It is mainly used to select the low taste ore, improve the grinding taste and reduce the cost of selecting ore. It can also be applied to non-magnetic materials except iron. How it works: when the pulp is poured into the tank, the ore is loose in the flow of the water to the tank. In the role of magnetic field, magnetic magnetic mineral grains occur together and form “magnetic group” or “magnetic chain” “magnetic group” or “magnetic chain” in the pulp by the magnetic force function, the movement to the poles, and adsorb on the cylinder. Due to the polarity of the magnetic poles along the cylinder rotate direction interwoven, and fixed at work, magnetic group “or” magnetic chain “in the cylinder rotates, with alternating polarity magnetic stirring, was mixed in the” magnetic group “or” magnetic chain “of the gangue and other non-magnetic minerals in turn off, has finally been sucked on the surface of the cylinder, the “magnetic group “or” magnetic lotus “is concentrate. Concentrate on the cylinder to the edge of the magnetic magnetic department the weakest place, under the effect of discharge ore hoses, washing water is discharge to concentrate in the slot, if it is full magnetic magnetic roller, mine was conducted with brush roll. Non-magnetic or weak magnetic minerals in pulp with pulp discharge groove, known as tailings.
Magnetic system is compounded of ferrite and permanent magnets; the average magnetic induction intensity of cylinder surface is 100 ~ 600mT.The same cylinder can be equipped with three types of tank adapting to different dressing process. Small area taken, good separation for magnetic mineral, reduce the load of next process. Permanent magnetic drum separators have 3 kinds including downstream type, counter flow type and semi-counter flow type according to the difference of base structure. Downstream type permanent magnetic drum separator: sIurrv flows in the same direction with drum.
Counter flow type permanent magnetic drum separator: slurry flows over against drum, which create great conditions for cleaning of non-magnetic ores. The non-magnetic ores approach the clean surface of drum and the magnetic ores can be absorbed in the strongest magnetic field. Semi-counter flow type permanent magnetic drum separator: slurry is fed into cavity from the bottom of drum, and the magnetic ores fall into concentrate tank after reaching a certain height, while the non-magnetic ores will enter into tailings tank along with slurry in the opposite direction with drum.
