Souwest Magnetic Separator

A magnetic separator is a device to separate various material compositions on the basis of their magnetic properties. Since 19th century magnetic separation processes have been used to concentrate and separate minerals. Ferro magnetism, paramagnetism and diamagnetism are the three important properties of the minerals. Ferro magnetic minerals are themselves magnets hence they stick to the magnets and can be easily removed later on. Paramagnetic and diamagnetic minerals interact with a magnetic field in a different way.

Paramagnetic minerals are weakly attracted into a magnetic field and diamagnetic minerals are weakly repelled by a magnetic field. Therefore if a mixture of paramagnetic and diamagnetic minerals is passed through a magnetic field, they will be pulled into the field (paramagnetic) or repelled from the field (diamagnetic) and may be separated. The electromagnetic separator separating the minerals consist of electromagnets or rare earth magnets of varying size and strength.

The low profile Souwest magnetic separator, which includes a secondary air wash separator, is designed to magnetically pull steel shot or grit from sand or other non-ferrous material using a magnetic rotating drum.

This magnetic separation process significantly increases the ability to remove sand from the steel shot or grit under extremely heavy sand load conditions. The addition of the magnetic separator to foundry blast equipment increases the life of the machine because sand is the primary cause of wear on foundry blast equipment. The magnetic separator reduces blast cycle times, increases the life of replacement parts and reduces equipment maintenance and abrasive consumption operating costs. Additionally, the magnetic separator reduces the air ventilation requirements for shot blasting equipment, and the horsepower savings reduces the total system requirements. The magnetic separator is easy to install on both Souwest and non-Souwest blast equipment.

The magnetic separator is part of the Souwest Plus program, which is the parts, equipment modernization and service division of the NingBo Souwest that helps customers improve the efficiency of their existing blast equipment operations.
