VIBRA-DRUM® Grinding Mill

General Kinematics VIBRA-DRUM® Grinding Mills are proven in dozens of milling applications in the mining and mineral industries. Because of this flexibility, they are the perfect solution for your needs, no matter the grinding processes you use.

The Grinding Mill can achieve impressive energy savings (up to 35-50%) thanks to a unique rotational material motion that is more efficient than conventional ball or rotary grinding mills. New processes such as micron grinding and mechanochemical grinding give customers a unique and effective competitive advantage. The units are also ideal for continuous processing of “difficult-to-fluidise” products such as large flake and stringy or tacky materials. Typical VIBRA-DRUM® Grinding Mill applications include direct gas contact heating, drying, cooling and coating.

VIBRA-DRUM® Grinding Mills excel over conventional ball, stirred media, or vertical roller mills in both grinding and energy efficiency. Features include:

  • Proven energy savings up to 35-50% reductions in kW hours per ton of processed material
  • 5 to 10 times longer media life
  • No trunnions, wheels, gears, or drive reducers
  • Few moving parts assure low maintenance
  • Adjustable media action, from gentle to aggressive
  • One half the liner requirements of typical rotating designs
  • Easy installation, with low dynamic reaction force eliminating massive foundation requirements
  • Recoveries of 93-97% can be achieved without the use of toxic chemicals such as arsenic due to the unique fracturing in the ore as well as GK’s leaching solution
  • The system is fully automated
  • In-situ leaching eliminates external leaching componentry and helps control chemistry.
