VIBRA-DRUM® GRINDING MILL & SOLUTIONS

MAXIMIZE MATERIAL RECOVERY WITH GK’S VIBRA-DRUM® TECHNOLOGY FOR GRINDING, CRUSHING AND LEACHING!

General Kinematics VIBRA-DRUM® Grinding Mills are proven in dozens of milling applications in the mining and mineral industries.
Each grinding mill is achieving impressive energy savings (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 our customers a unique and effective competitive advantage.
VIBRA-DRUM® Grinding Mill units are also ideal for continuous processing of “difficult-to-fluidize” 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.

HOW IT WORKS:

Exceptional grinding performance and energy savings are the result of the VIBRA-DRUM® 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 increased number of impacts in the VIBRA-DRUM® Grinding Mill results in a faster, more efficient grinding action. As the grinding mill vibrates, media particle migration is experienced in both axial and transverse directions. In fact, the media migrates through the VIBRA-DRUM® Grinding Mill in a path similar to that of a rotary grinding mill without lifters, but each media particle imparts positive impact energy at each vibration.
The area where comminution takes place is larger and more efficient compared to a rotary grinding mill of similar size. There are no dead zones of inactive media inside the vibrating grinding mill. And, unlike stirred or tower grinding mills which grind by attrition, the VIBRA-DRUM® Grinding Mill uses the principle of impact grinding which causes clean breaking and does not coat the mineral/gangue with slimes.

The VIBRA-DRUM® Grinding Mill 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.

MINIMAL INSTALLATION COSTS:

The capital cost of a VIBRA-DRUM® Grinding Mill is significantly less than a rotary grinding mill containing a comparable media load. There are no drive speed reducers, ancillary machinery, nor large support bearings. The VIBRA-DRUM® Grinding Mill has very few moving parts.

A VIBRA-DRUM® Grinding Mill does not require the typical massive concrete foundation required of a conventional rotary grinding mill unit. Structural steel supports are designed as an integral part of the VIBRA-DRUM® Grinding Mill and simply bolted to a suitable load-bearing floor.

The grinding chamber in the VIBRA-DRUM® Grinding Mill requires replaceable liners on only 60% of its circumference, representing a considerable saving in initial installation and mill downtime. Theoretically the VIBRA-DRUM® need not be a tube shape, however, this shape was chosen because of its shell strength.

Contrary to rotating devices the VIBRA-DRUM® Grinding Mill offers the advantage of relatively static access to the mill while it is operating. The controlled addition and even distribution of chemicals, the sampling of material in progress, or the discharge of product at any point in the mill offers endless possibilities.

LEACHING APPLICATIONS:

The VIBRA-DRUM® in a wet grind leaching application provides efficient chemo-mechanical processing of ore bodies for precious metal recovery.
