bond work index test ball mill 911metallurgist. The FC Bond Work Index Test Ball Mill was designed by F. C. Bond for use in determining the Bond Index, a measure of grindability and power required for grinding applications. The FC Bond Mills are used in laboratories throughout the world.Ball mills usually operate at 65% to 75% of the critical speed. The critical speed is calculated as under [5]. R r g 2 1 n c (2) 2.1.3 Work Index: Work index is defined as the gross energy required in kilowatt-hours per ton of feed needed to reduce a very large feed to such a size that 80% of the undersize passes through 100-µm screen [5].

The electric power consumption of the three ball mills (PT, Pa and P~) is shown in Figure 16, together with their references (P*7, P*8 and P*9)" The electric power to ball mill No. 8 assumes values beyond the lower limits (1200 [TPH]) for the penalty function at around t=20 [mini, which causes the tonnage reference to fall quicker.The work index expresses the resistance of the material to grinding. It represents the kilowatt hours per tonne required to reduce the material from theoretically infinite feed size to 80 passing 100μm (Wills and Napierpercent -Munn, 2006). Bond devised several methods for predicting ball-mill and rod-mill energy requirements and
