1、 Explanation:

The HMDN coal washing special magnetic separator is a fully countercurrent wet magnetic separation equipment designed specifically for the recovery of magnetic media in heavy medium coal preparation plants. Drawing on advanced technology and design concepts from Europe and America, and after years of use and improvement by our company, the recovery rate has been greatly improved compared to similar equipment in China.

The heavy medium content in the feed slurry can range from 87-260kg/m, and the heavy medium recovery rate can reach 99.7% -99.9%. The tank body is made of stainless steel material, which prolongs the service life of the whole machine. This machine can continuously feed and discharge ore, and can also be used in series with double tubes to make sorting more efficient.

The principle is that when the slurry enters the magnetic field zone, strong magnetic minerals are adsorbed on the surface of the cylinder, weak magnetic and non-magnetic minerals are washed away by water flow, and the magnetic minerals adsorbed on the surface of the cylinder are carried out of the magnetic field zone by the rotation of the cylinder and washed into the concentrate tank with washing water to complete the sorting operation.
