Working principle of high gradient magnetic separator
The structure of Sinonine vertical ring high gradient magnetic separator is shown in the figure below. It is mainly composed of excitation coil, iron yoke, rotating ring and various ore buckets and water buckets. The magnetic conductive stainless steel plate mesh or round rod is used as the magnetic medium. Through direct current, the excitation coil generates an induced magnetic field in the separation-area, and a non-uniform magnetic field, that is, a high gradient magnetic field, is generated on the surface of the magnetic medium in the separation area. The rotating ring rotates clockwise to continuously feed and transport the magnetic medium into and out of the separation-area; The slurry is fed through the feed bucket and flows through the rotating ring along the gap in the upper yoke. The magnetic particles in the slurry are adsorbed on the surface of the magnetic medium, and are carried to the top non-magnetic field area by the rotating ring and is flushed into the magnetic product bucket by the rinse water. The non-magnetic particles pass through the magnetic medium under the action of gravity and fluid force, separate from the magnetic particles, and flow into the non-magnetic product bucket along the lower iron yoke gap.

Case：
1.Australia LHGC2500 high gradient magnetic separator
This equipment is used for removing iron in quartz sand production line. It is combined with plate magnetic separator and drum magnetic separator to remove residual iron in quartz sand, and the removal effect is very ideal.
2.Pakistan LHGC2000 high gradient magnetic separator
This equipment is used to remove iron from kaolin. After being washed and cleaned, the kaolin slurry enters LHGC2000 high gradient magnetic separator to remove the residual iron and obtain high-purity and low-iron kaolin products. The iron removal rate is above 90%.
High gradient magnetic separator is a highly technical high-intensity magnetic separator,, it can generate more than 1.5T strong magnetic field, the weak magnetic material can be removed to the maximum extent, it is a non-replaceable magnetic separator equipment. I choose to cooperate with Sinonine is based on the trust of its technology, coupled with good after-sales service, to provide good guarantee for my whole project. At present, I have purchased a series of magnetic separation equipment, including high gradient magnetic separator, which has been running for many years without any fault. It is a very stable equipment and plays an irreplaceable role in the operation of the production line.
