Magnetic Separation Equipment

Stearns Magnetic Drums

Stearns Magnetic Drums are designed to improve efficiency in handling heavy volumes of large size material encountered in today’s scrap and slag processing and mineral concentration applications. The drum consists of an electromagnet assembly mounted inside an outer rotating drum assembly. The magnet assembly position, although stationary during operation, may be adjusted within certain limits to meet varying feed arrangements.

  • Heavy duty manganese steel cylinders and knock-offs provide extended service life
