The FC Bond Ball Mill is a small universal laboratory mill used in calculating the made in the Bico Mill rurming at 70 revolutions per minute with a charge of285 iron balls lhe work requircd is proportioDal to the rcdultioo in volume
Cement mill notebook SlideShare Jan 7 2015 Nael Shabana 201012 443 Total Grinding Ball Charges Weight Bulk volume of the grinding media in the mill Vm Useful mill volume V 48 t m3 Specific gravity is 7879 t m3 Example Calculate the charge of grinding balls of a threecompartment mill for dry grinding of cement raw mix
Ball top size bond formula calculation of the top size grinding media balls or cylpebsModification of the Ball Charge This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency
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
The majority of grinding balls are forged carbon or alloy steels Generally they are spherical but other shapes have been used The choice of the top or recharge ball size can be made using empirical equations developed by Bond 1958 or Azzaroni 1984 or by using special batchgrinding tests interpreted in the content of population balance models Lo and Herbst 1986 The effect of
Number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge For the initial chargin of a mill Coghill and DeVaney 1937 defined the ball size as a function of the top size of the feed ie dâ†“V 040 KâˆšF dB ball size cm
Dec 08 2009 · Re how to estimate the wear rate for Ball mill Most practical way to by measuring empty height and calculating the volumetric filling of grinding ative way to make track of mill main drive kW consumption reduction and add makeup charge
In Grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often the ball used in ball mills is oversize “just in case” Well this safety factor can cost you much in recovery andor mill liner wear and
