Girth gears (Gear wheels) 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 industries used in various types .
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 Vbelt drives or reducer drives. Spur gears and pinions are cut with teeth of the full depth involute .

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
The Mill was purchased second hand and the pinion and girth gear have pitting spalling and a 7deg C temperature differential across the pinion. So some misalignment but very close to acceptable limits As suggested if I could get access to some high resolution data of the gear mesh frequency then see the spacing of the side bands.
The girth gear is the major component used in rotary kiln and ball grinding mill which is required to be operated in a long time So, the quality requirements during the actual production for the big gear .
