This drive train has been well proven over many years of service as a fixed speed drive and offers major benefits over any other arrangement. As mill size increased above approximately 4,476 kW (6,000 hp), the limits of gear technology were reached and it was no longer possible to drive through a single pinion.

Ball Mill Application and Design

A vibratory grinding mill will have several hundred cycles per minute of media opening and closing. The high number of impacts is combined with speed and stoke settings to produce up to 5 g's of amplification on the media. Thus General Kinematics vibratory grinding mills create a higher energy grind due to the use of their kinetic energy.

SAG Mill Variable Speed Drive

The QdX4™ Mill Drive was developed in close collaboration with both CMD and Ferry Capitain Engineering as a solution for the mining industry for large mill drives. The QdX4™ Mill Drive features internal torque splitting capability transmitting motor input power to the pinion shaft and equally dividing into two mill pinions.

HIGH INTENSITY GRINDING ISSUE 32 AT ITS FINEST

The particle grinding mechanism in stirred milling is almost attrition or shear type grinding,, rather than impact grinding as occurs in tumbling mills, like SAG and ball mills. Large particles (> 1 mm) can be efficiently reduced in size by impact grinding where the breakage method is shattering of particles by direct fall upon them from ...

Drive mechanism: The means for turning the rollers can vary considerably. For the small amounts of grain a homebrew mill must crush, the simplest solution is to drive a mill using an ordinary crank handle. The small diameter of rollers on homebrew mills, however, may require a bit more patience during cranking sessions.
