CALCULATION OF THE POWER DRAW OF DRY , by Erdem (2002) for dry multicomponent cement grinding ball mills, using the results of the Bond ball mill grindability test For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw Morrell (1996) proposed a In general, therefore, the required mill power is calculated using the following equation where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill How to Size a Ball Mill Design Calculator Formula Figures 5 and 6 respectively Accurate measurements of the ball filling can only be made after the mill is ground out In this case the mill is operated with the feed turned off until all of the ore has exited the mill Measurements of the ball level within the mill can then be made Figure 7 shows an example of the balls in a mill after a GROSS POWER CALCULATOR SMC Testing
