  • We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media While the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill The loading or change volume can then be read off the graph below or...

  • As the ball wear rate depends directly on the surface of the media charge a small variation in power will lead to an important increase of wear rate The risk of underloading or overloading the mill is an additional factor A direct measurement of the ball level in the mill more accurate than power readings as well as a control of it is...

  • The best way to measure load is to mount the mill on load cells The load cells are calibrated to measure the total weight of water grinding media balls and ore in the mill but not the weight of the mill itself While many mills today are mounted on load cells others employ bearing oil pressure as a proxy measurement of mill load...
