The ball mill is designed for the dry comminution of hard materials, especially for the ultrafine range < 10 µm in circuit with an ALPINE ultrafine classifier. Ball mills are giant drums that are filled with between 30 and 40% of their volume with freely moving grinding media, in this case balls. The diameter of the balls is between one and several centimeters to suit the application ...

· length:diameter ratios for ball mills are normally 1:1 to 5:1. 3. the slower the speed the less wear on media and liners, 4. the faster the speed the lower is the capital cost. The highlighted box in the table above indicates suitable mill dimensions. These calculations are an approximation only and the mill manufacturers should be consulted for final mill selection. Theoretical Mill ...

Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of meters and length of meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The lengthtodiameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and ...

optimum ball diameter" (Taggart, 1945). • Test mills used for media sizing investigations need to be reasonably large (at least m in diameter was suggested), depending on size of balls and ore being tested. • Ball surface wear rate is approximately constant, but with variations due to hardness, and other factors. Consumption is closely related to total ball charge surface area. • A ...
