  • Ball Mill Design/Power Calculation

    The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and

  • Calculating Power Draw when sizing Ball Mills

    I’m 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

  • CALCULATION OF THE POWER DRAW OF DRY

    Calculation of the power draw of dry multi-compartment 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. A

    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, semi-autogenous 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

  • Charge behaviour and power consumption in ball

    Effect of mill fill level on power draw as a function of mill speed, (a) power draw and (b) power consumption/tonne. The torque required to support the charge in an off center position is essentially the product of the weight of the charge and the horizontal distance between the COM of the charge and the center of the mill.
