(PDF) ball mill | Sheetanshu Pandey
For a gear-driven ball mill, use the following: Total Ball Mill Motor Power = (Ebm × tonnes/hour) ÷ 0.985 ÷ 0.94 ( 10 ) The largest motor sizes currently on the market with pinion and gear drives are in the 10 MW range (these would be a twin-motor arrangement with one motor on either side of the mill).
