• #### Mill (grinding) - Wikipedia

Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral ...

• #### Sugar - Milling Tandem Capacity

The problem with M. Hugot's equation is that is a function of the square of the mill speed, which means mathematically that the mill capacity will increase with speed, reach a maximum and then deacrease, as the speed increases. This could be interpreted in an engineering sense that the mill will have an optimum speed to operate at beyond which the capacity deacreses due to slippage of bagasse ...
