Introduction and Using field

The dry magnetic separator is a new type of dry separation equipment developed by Yanhe company after years because of market experience. It can produce a 1-10 layer structure according to demand and achieve multiple material sorting.

This equipment has good sorting effect on small and medium-sized granular ores with low but uniform powder ore rate, high production efficiency, and simple and convenient operation. For manganese ore, Hematite, pseudomorphic Hematite, specularite, Siderite, manganese ore, Chromite, Goethite, Limonite, Siderite, Chromite, niobium Tantalite, ilmenite, Wolframite, iron quartz ore, Apatite, Xenotime, olivine, chalcopyrite, Biotite, Epidote, Serpentine subgroup, primary Ilmenite, seashore placer, primary Rutile, Dry magnetic separation of Wolframite and most rock forming minerals quartz, feldspar, Calcite, Biotite, Amphibole, olivine, Tourmaline, pyroxene, etc. is effective.

Working principle

Its operating principle is that the material falls into a constant speed feeding device through the silo, and before entering the magnetic separation area, the material and magnetic substances are vibrated by gravity and vibration through the feeding device, so that the adhered or wrapped magnetic substances are basically dispersed. And it can be evenly sent to the magnetic separation area. Under the action of gravity and magnetic field force in the magnetic separation area of the equipment, the magnetic difference of the material has different movement trajectories to achieve separation. Magnetic minerals are adsorbed on the surface of the magnetic roller and rotate to reach the concentrate area. The brush will remove the magnetic minerals adsorbed on the surface of the magnetic roller.

Due to the polarity of the magnetic pole along the direction of the cylinder rotation is alternately arranged, and fixed at work, "magnetic group" or "magnetic chain" in rotation with the cylinder, due to the magnetic pole alternating magnetic stirring phenomenon, be included in the "magnetic group" or "magnetic chain" in gangue and other non-magnetic minerals fall off in the flip, and eventually be sucked on the surface of the cylinder "magnetic group" or "magnetic lotus" is the concentrate. Concentrate with the cylinder to the magnetic edge of the magnetic system is the weakest, in the discharge of ore water pipe under the action of flushing water is discharged into the concentrate tank, if it is full magnetic roller, discharge is carried out by brush roller. Non-magnetic or weakly magnetic minerals are left in the pulp with the pulp out of the tank, that is, tailings.
