VIBRA-DRUM® Grinding Mill
General Kinematics Vibra-Drum grinding mills are proven in dozens of milling applications in the mining and mineral industries. Grinding processors are achieving impressive energy savings (35-50%), thanks to a unique rotational material motion that is more efficient than conventional ball or rotary mills. New processes such as micron grinding and mechano chemical grinding give our customers a unique and effective competitive advantage.
Exceptional grinding performance and energy savings are the result of the Vibra-Drum's natural frequency design. A sub-resonant, two mass drive and spring system alternately stores and releases grinding power. Once in motion, energy is only needed to move the grinding media as a fluid mass, and to overcome frictional losses. The Vibra-Drum can be used for processes other than grinding. It has been used to process and agglomerate fiberglass, mix product components, clean castings, for hydrometallurgy, minerals recovery, and other processes.
Maintenance
Minimal mechanicals and innovative engineering combine to provide you with grinding equipment with low maintenance and downtime requirements.
 Maintenance of VIBRA-DRUM products consists of:
- Periodic lubrication of motors.
- Easy liner replacement system uses clamp bars for quick replacement.
- Access doors allow easy inspection of media and liner.
- Media changes simplified by removal of endcap bolts.
Features
VIBRA-DRUM® grinding mills excel over conventional ball, stirred media, or vertical roller mills in both grinding and energy efficiency.
- Proven energy savings range from 35 to 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 assures low maintenance.
- Adjustable media action, from gentle to aggressive.
- One half the liner requirements of typical rotating designs.
- Easily installed. Low dynamic reaction force eliminates massive foundation requirements.
