Know MoreTo calculate Bond rod-mill work indices, the four samples were screened and the particle size distributions plotted in Fig 2The plot was used to find F 80 of the samples for calculations Fig 3, Fig 4 show the grinding kinetics of Pb, Cu, Fe, and Mn ores in the Bond rod-mill in different test-siev The slopes of all lines in the figures are equal to the k value of Eq...
Know MoreThe heavier rods acting upon the lifters and liners result in greater wear on the mill liners Rod mills normally carry 35 to 65% rod charge by volume The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge ....
Know MoreGenerally, Bond work index is a common method for selecting comminution equipment as well as estimation of grinding efficiency and calculating required power In the current research, a simple, fast and accurate procedure is introduced to find the...
Know MoreDuring operation of rod mills, rods have to be replaced occasionally as they are subjected to wear and liable to break The replacement rate should be equal to the rate at which rod size deterioration occurs so that equilibrium is maintained Bond determined the equilibrium rod sizes in ,...
