Magnetic separator is one of the most widely used and high universality in industry, it is suitable for reusing to remove iron powder in the powder granule etc. Magnetic separator is widely used to recycling in wood industry, mining, ceramics, chemical, food factory and other factories. Magnetic separator is suitable for wet or dry magnetic separation with the size within 3mm materials of the manganese ore and magnetite, pyrrhotine, roasted ore and ilmenite , which is also used to separate the iron in coal, nonmetal ore, building materials etc.
Classification
According to the different structure of tank, Magnetic separator can be divided into downstream type, counter-current type, half counter-current type. The feeding size of three different type magnetic separator as follows : downstream
tank ≤6mm, counter-current tank ≤1.5mm, half counter-current type≤0.5mm.
Structure
The wet permanent magnetic drum magnetic separator mainly contains drum, roller, brush roller, magnetic department, tub, transmission . The drum is rolled and welded through 2-3mm corrosion resistant plate, The end cover is cast aluminum or workpiece, connect with stainless screw and drum.

Working principle
Pulp flow into tank through feed box , under the action of feeding water spray's water flow , mineral grain go into the feed mining area of tank in the manner of loose.Under the action of magnetic field, magnetic magnetic mineral grains occur together and form "magnetic group" or "magnetic chain" , Magnetic group" or "magnetic chain" are affected by magnetic force in the pulp , movement to magnetic pole, and yet adsorbed on the cylinder. Due to the polarity of the magnetic pole along the drum rotation direction are arranged alternately, and fixed at work, "Magnetic group" or "magnetic chain" rotates along with cylinder, which occur magnetic stirring With alternating magnetic, The gangue and non-magnetic minerals with"magnetic group" or "magnetic chain" fall off when rotating . The "magnetic group" or "magnetic chain" that was eventually absorbed on the surface of the cylinder is concentrate . Concentrate gets to the most weak place of Magnetic system edge with the cylinder rotating , which is discharged concentrate tank under the action of discharging ore hoses flushing water, If it is all-magnetic magnetic roller, the brush roll is used to dump mine. Non-magnetic or weak magnetic minerals in pulp is discharged from discharging groove, which is the tailing.
Advantage of wet magnetic separator
Wet magnetic separator magnetic system is composed by the high quality or compounded with magnets, the average magnetic induction intensity of magnetic drum surface is 100 ~ 600 mt. According to customer 's request ,we can supply magnetic separator with different magnetic induction intensity of magnetic drum such as downstream type, counter-current type, half counter-current type. The advantages of our magnetic separator are simple structure, large capacity, convenient operation, easy maintenance, etc.
Application
Wet magnetic separator is suitable for wet magnetic separation with the size within 3mm materials of the magnetite, pyrrhotine, roasted ore and ilmenite , which is also used to separate the iron in coal, nonmetal ore, building materials etc.
