Electrostatic Separators

Bunting's Electrostatic Separator uses electrostatic charge to separate dry, liberated particles with different levels of electrical conductivity. This technology is commonly used in the mineral processing, plastics, and recycling industries to separate conductive materials from non-conductive (insulating) ones.

Drawing on over 65 years of experience in magnetic separation and material handling, Bunting has developed ElectroStatic Separators to address the growing need for sustainable, water-free separation methods. These systems are designed to handle a variety of materials, including minerals, plastics, and metals, supporting efforts to improve product quality, reduce waste, and recover valuable resources.

The separation process requires no water or chemicals, minimizing environmental impact. Each unit can be configured to meet specific operational needs, with control systems that support consistent, reliable performance across a range of applications.

Bunting’s ElectroStatic Separators are used in mineral processing, plastics recycling, e-waste processing and lithium ion ELV recycling where accurate, dry separation is essential. We work closely with customers to tailor solutions that align with their material recovery goals and process requirements.
