Classification

Dry magnetic separator is widely used to separate the less than 2-3 mm weakly magnetic minerals and the concentration of rare metal ore. There are three kinds of dry type magnetic separators as a single plate (φ= 900 mm ), double plates ( φ= 576 mm) and three plates (φ=600mm)

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.

The advantages of dry type magnetic separator

Dry type 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.The advantages of our magnetic separator are simple structure, large capacity, convenient operation, easy maintenance, etc. Dry type magnetic separator equipment has disturbance magnetic field and the characteristics of high separation factor, advanced structure, light weight, reliable operation, easy maintenance.Dry magnetic separation machine is suitable for droughty Water Scarce Areas, saving water, reducing the processing cost, it is a new way to mine and utilization ultra lean magnetite.

Application

Dry type magnetic separator is the commonly used iron ore and manganese ore equipment, which is main high intensity magnetic separation of the beneficiation equipment. Dry type magnetic separator is a special magnetic separation machine which is used to separate dry magnetic mineral, Relative to the efficiency that wet type magnetic separator separate mineral is higher when liquid is used as a diluent. It is necessary for dry type magnetic separator that the separated mineral is dry, the different particles can move freely and independently,otherwise it will influence magnetic separation effect, even can not separate the mineral.  Dry magnetic separator is suitable for wet type magnetic separation with the size within 3mm materials of the magnetite, pyrrhotine, roasted ore and ilmenite etc, which is also used to separate the iron in coal, nonmetal ore, building materials etc.
