Ring gear drives huge grinding mill Machine Design

Located at Kennecott Utah Copper near Salt Lake, this mill uses a ring-motor drive, Figure 5. The SAG mill is followed by two 20-ft diam., 7,500-hp gear-driven ball mills.

Suitable Starter for Ball Mill Starting Through Slipring

2011-6-25  (1) Generally LRS is used for Cement Ball mill application. In some process plants LRS / FCMA is also used. Ball mill application is basically constant speed application. Please note that, LRS / FCMA are used with slip ring motor. In slip ring motors maintenance is big problem (wear and tear of brushes, brush assembly, etc).

Gearless mill drives ABB

2019-1-3  The poles of the gearless or synchronous motor (also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.

Ball Mill Gear Mineral Processing & Metallurgy

2021-1-22  Two general classifications of gearing are used for ball Mill drives. These are the spur gear and the helical gear. Helical gearing may be either of the single helical or double helical (Herringbone) design. SPUR GEARS These are generally furnished on the smaller diameter mills using V-belt drives or reducer drives. Spur gears and pinions are cut with teeth of the full depth involute tooth

TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS

2018-5-10  answered. Depending on the mill size and type, the mill can be driven by several configurations of drive systems. The main options are single low speed motors connected to a pinion driving a ring gear, two low speed motors connected to two pinions and driving a ring gear, or a gearless motor mounted directly onto the mill. In addition, a gearbox
