HOW BALL MILL WORKS. Oct 10 2016 · In long ball mills the grinding occurs only at the front and the rest of the balls in the drum only increases power consumption Drum mills have one grinding chamber short and long ball mills and two or more grinding chambers long and pipe ball mills Singlechamber continuous mills are the main equipment at mining and processing plants
In broad terms, this makes SAG mills less expensive to build (in terms of unit capital cost per ton of throughput) than AG mills but more expensive to operate (as a result of increased grinding media and liner costs, and in many cases, lower power efficiency).

Castro and Valenzuela [2, 3] studied the electromechanical coupling model of a SAG mill. The simulation results were compared with the field record data during start-up and shutdown of the SAG mill. Guerrero and Pontt investigated the oscillatory torque caused by dead time in the current control of a high-power gearless mill drive.
FFE gives the mill details thus: 8.23 metres inside shell diameter; 12.19 metres effective grinding length; 12.8 metres between flanges; and dual 7,000 motors. That makes it the largest low-aspect, dual-pinion gear-driven mill ever to be designed and built. The new mill has an annual throughput of 4.2 million tons of ore.
design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings.
All parameters above are good for a 22.5MW to 24MW dual pinion SAG mill drive. Changes to AGMA standard have revitalised the large gear cutting industry and soon a machine shop in Holland will be able to fabricate gears of the following parameters: 20 meters in diameter = 65.6 feet 1.5 meters in face width 400 tonnes of machined weight.
