Magnetic Disc Separator

Bunting Magnetic Disc Separators separate dry, granular minerals according to magnetic susceptibility. The equipment supports mineral processing, recycling, and recovery applications that require multiple product streams from a single feed.

Up to three electromagnetic discs can be set independently between 1,000 and 20,000 gauss. Adjusting each disc's field strength, height, angle, and speed lets operators target materials with different magnetic responses.

Typical applications include mineral beach sands, tin and tungsten concentrates, black mass, coltan recovery, quartz purification, and recovery of metals from electronic waste. The design can produce up to seven material streams in one pass.

Bunting also offers laboratory-scale testing to establish practical separation settings before equipment selection. Test results help define the configuration for the customer's material and required outputs.

Adjustable separation: Set each disc from 1,000 to 20,000 gauss to target materials with different magnetic susceptibility.

Multiple outputs: A three-disc configuration can produce up to seven material streams in a single pass.

Process control: Adjust disc height, angle, speed, and magnetic field strength to suit the feed material and required separation.

Laboratory testing: Test representative samples before equipment selection to establish practical settings and expected results.

Mineral and recycling applications: Process dry materials such as beach sands, coltan, quartz, tin and tungsten concentrates, black mass, and electronic waste.
