According to Eq. 1, mill power is a function of ball mass (M b) and the distance between mill center and the center of gravity of ball mass (r g). So, as the mill filling increases M b goes up, but r g decreases. Therefore, the power draft passes through a maximum. However, the value of this critical mill filling is also influenced by other operating factors. DEM numerical calculation

Mill Power Draw. The motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill. It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) nCALCULATION OF THE POWER DRAW OF DRY,given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill. He also verified his approach with various plant data (Napier-Munn et. al., 1996). In this study, power draw of 14 multi-compartment cement grinding mills were calculated based on Morrell’sGROSS POWER CALCULATOR - SMC Testing,calculations by the user. If the mill has cone ends the model automatically calculates the volume of the cone ends as well as the volume of balls/rock in the cone ends from the cylindrical section data that the user inputs. In SAG mills the total filling relates to the combined rock and ball volume (including voids), whilst in AG mills it relates just to the rocks (including associated voids,How Calculate Mill Power - obcane-kralovedvorska,Ball Mill Design/Power Calculation.

The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models. Models of this type do not predict the particle size distribution of a milled,
