Ball Mill Design Autogenous mills range up to 12 meters in diameter The length-to-diameter ratios in the previous table are for normal applications For primary grinding, the ratio could vary between 1:1and 18:1 For fine regrinding in open circuit, the ratio ranges from 13:1 to 15:1

liming overflow ball mill sizes range from 5 ft x 8 ft with 75 HP to 30’ x 41’ and as much as 30,000 HP Larger ball mills are available with dual pinion or ring motor drives Our mills incorporate many of the qualities which have made the Marcy name famous since 1913 These heavy-duty machines are designed for long life and minimum maintenance

Rod mills are very similar to ball mills, except they use long rods for grinding media The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 14 to 16

Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30] Cylpebs are slightly tapered cylindrical grinding media with rounded edges and equal length and diameter with sizes varying from 8×8 to 45×45 mm

The optimal ball diameter in a mill 335 By the method of the least squares, it was possible to determine the numerical values of parameters K and n in Eq 1, with a very high degree of correlation r, so that they, for the conditions of our experiment, would be as follows: quartz: 2267d 087 bo

SAG mills are characterized by their large diameter and short length as compared to ball mills The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge

Ball mill The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or stone Less wear takes place in stone lined mills The length of the mill is approximately equal to its diameter
