ball size calculation for ball mill Ball Mills Mine Engineer Ball Mills are generally used to grind material 14 inch and finer, down to the particle size of 20 to 75 microns.
The model is equally applicable to ball, semiautogenous and autogenous mills and contains a description of the power draw of both the cylindrical section and the coneends.
Power Draw Calculator Of Ball Mill . e model calculations for ball mill power draw by steve morrell gross power calculator SMC Testing This model uses the equations from Morrell s 1993 PhD thesis The power at pinion would be about 7 lower than the gross power draw are grate discharge and ball mills are mostly overflow a few however are grate discharge
Modern mills operate with load cells and mill optimizer39s which synchronize the mill weight, power draw, ore feed and weight with density control. Where optimizers are not used, the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge this allows bed expansion by the slurry filling the voids

Yesterday I calculated the power draw of our ball mill. I attach a graph of it. Is it possible to have calculated mill power draw to be greater than mill motor HP Calculated mill power draw is 1,509 HP Mill motor HP is 1,500 HP According to the calculations, at 54 mill volumetric loading, max power draw of 1,796 HP is obtained.
Ball Mill Power Draw Calculation . Ball Mill Power Draw Calculation. At a constant mill filling, the power draw was changed with changing the ball size distribution and for all mill fillings the maximum power draw occurred when the fraction of small balls was between 3040he effect of ball size distribution increased with.
Calculation of the power draw of dry multicompartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.
Ball Mill Screening Designed From Nigeria. The proposed model combined with a model giving the ballmill power draw gv eds scale up and dynamics of large grinding millsa case study in design and get quote design and analysis of ball mill inlet chute for roller press circuit aug 26 2014 for design
Im interested to know when sizing a new ball mill, as to why recirculating load has no effect on the power calculation, although it will have effect on volumetric capacity naturally. For instance a mill of 300tph with a 300 recirculating load would have 1200 tph going through effectively, but if
Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600 Calculated ballmill power draw from the m odel derived, kW Data compared Line yx Fig. 2. Comparison of the ball mill power draw from the Denver slide rule and the proposed model. Dashed line corresponds to yx.
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters 10 feet diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos AllisChalmers
predicted. Slurry pooling causes the power draw in AG and SAG mills to be lower than a mill without a slurry pool. This phenomenon results in overflow mills usually drawing less power than grate discharge mills that are operating without a slurry pool. This is because by definition overflow mills operate all of the time with a slurry pool.

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load medium and charge. Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential
