processing at an ore mill at Bougainville, New Guinea. Since then innovation has continued with the first GMD for a double-rotating ball mill in Carlin, Nevada, meeting a 160 °C heat challenge at the mill shell. GMDs have now been supplied for the world's largest autogenous (AG), semi-autogenous (SAG) and ball mills, fulfilling the highest power

SAG mills generate higher levels of impact reduction and ball mills higher levels of abrading action. A mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action.

Ball mill shell supported design In mining industry, ball mills normally operate with an approximate ball charge of 30% with a rotational speed close to 11 rpm.

3. Operation of Tubular Ball Mills. Tubular ball mills ride on steel tyres or are supported at both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronous motors that operate through an air clutch or gear system.
