Read MoreThe sizing of ballmillsand ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill ...
Read MoreMaximumrodlength is limited to about 6.1 m (20 ft). This in turn limits the length, diameter, andcapacityofrod mills. The heavierrodsacting upon the lifters and liners result in greater wear on the mill liners.Rod millsnormally carry 35 to 65%rodcharge byvolume.

Therodmill motor power is in horsepower at the mill pinion-shaft. For different lengthrod millspower varies directly asrodlength. For difference between new and worn liners increase power draw by 6%, and adjust ...
Read MoreAs in ballmills, the power draft of arodmill is the product ofcapacityand work index, which is the energy required to break a mineral of a given size to the required size. The mill power is also increased by increasing therodcharge and the mill speed, while the mill power andcapacityare both increased with increasing mill length.

Read MoreAG/SAGmillscan accomplish the same size reduction work as two or three stages of crushing and screening, arodmill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventionalrodmill/ball mill circuit. A diagram of types of AG/SAG ...
