Bond Work Index Formula-Equation

See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um.

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL .

of other problems in a mill such as a power cut, mechanical problems of transportation or in the water cooling system. Problems of this kind can never really be calculated but they have a detrimental effect on all rolling schedules including stresses in the roll. As regards "abnormal" rolling conditions - which are more or less very "normal" for rolling mills - roll damage often occurs ...

Mill (grinding) - Wikipedia

Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the ...

Grinding Mill speed is one of the factors affecting the character of the cascading charge. As shown in the illustrations, the lower the percentage of critical speed, the smoother the flow of balls from top of charge to bottom. Higher percentage of critical speed is used for impact grinding of large feed. Lower percentage of critical speed is used for attrition grinding when a fine product is ...

Effects of mill feed size and rod charges on .

The effects of mill feed size reduction on wet rod grinding has been studied by Strohl [2]: when the percent passing 13 mm in the mill feed was increased from 84% to 98% in rod grinding, the fineness of ground products increased from 85% to 94% passing 0.5 mm, while there was a 10% increase in mill capacity and a 15% decrease in wear of the rods.
