Bunting Launches Electromagnetic Dry Filter

Bunting has developed an Electromagnetic Dry Filter to remove fine iron particles from powders in industries such as mineral processing, chemicals, pharmaceuticals, ceramics, and recycling. The high-intensity magnetic separator generates fields up to 12,000 gauss, capturing ferrous contaminants in fine materials. A vibrating canister with a magnetic stainless-steel matrix enhances separation efficiency, addressing flowability and electrostatic challenges often seen with rare earth magnetic separators.

Designed for controlled batch processing, the unit retains magnetic particles until separation is complete. When the electromagnet is turned off, collected material is released into a waste area before processing resumes. The filter integrates with production lines via a Siemens S7-1200 PLC and HMI control and includes a built-in jig crane for maintenance.

“The development of the Electromagnetic Dry Filter has been customer driven. Processing powders is often challenging due to the way in which the materials behave. Our design engineers considered these challenges when designing the Electromagnetic Dry Filter, focusing on good powder flow, whilst maximising magnetic separation.” said Adrian Coleman, Bunting’s Technical Director.
