Nov 25, 2009 Gearless motor drives are also known as “ring motors” or “wrap around motors.” The motor consists of a large number of magnets placed circumferentially on the shell of the grinding mill. This is similar to the rotor of a conventional motor. The stationary part, the electromagnetic coils, is a stationary ring encompassing the rotating.
Ball mill size excel calculation. Ring gear drives huge grinding mill Mechanical Drives content from Mar 1, 2000 Gigantic grinding mills excel at cutting copper ore down to size so it can.
Girth gears are large ring gears which are normally fitted to the outside of ball mills or rotary kilns to provide the primary rotational drive, which is required to be operated in a long time. So, the quality requirements during the actual production for the big gear ring are very high. Girth gears are applied in the mining, cement, minerals.

Key Words Grinding, ring-geared mill, variable speed drives, mill functions, measurements installed and commissioned 2 x 5 MW dual pinion ring geared mill drive system will be shown and discussed. Also the accuracy of the load sharing between the two 5 MW motors during pinion and ring gear, as no huge torque spikes .
On the larger ring geared mills, where the length of the pinion and ring-gear teeth is increasing, perfect alignment of pinion and ring gear (and gearbox in some cases) is pivotal. However experience has shown that it can be difficult to achieve and maintain perfect alignment.
When talking about ring geared mill drives (RMD’s) and especially dual pinion systems (see figure 1), the possibility to add mechanical stress by the motors can be significant. Therefore the control concept between the two motors must be fast and accurate to avoid any additional stress to the pinions and the ring gear. Figure 1.

Reliable gear unit components for a complete, adaptable side drive.
The main gear are within OEM specifications and c) the root clearance of the gear set is low. Loose drive components can facilitate resonance vibration, and such conditions must therefore be corrected. The attachment of the gear to kiln has to be secure that is, spring plate pins and gear bolts have to be tight. If a grid coupling is.
