  • ball mill design/power calculation

    now we much select a ball mill that will d this power. the ball mill motor power requirement calculated above as 1400 hp is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution.

  • optimization of mill performance by using

    mill power. usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. it is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration.

  • effect of grinding media charge on mill power d kw

    maximum power is dn by a mill when the charge occupies approximately 50% by volume. the power curve becomes very flat in the range above 45%. as a result, mills are seldom run with charge levels greater than 45%. in rod mills, the charge is swollen by particles of feed which separate the rods.

  • calculation of the power d of dry multi compartment

    calculation of the power d 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 d. estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous.

  • rod mill design and power d

    power d is related directly to mill length, and, empirically to the diameter to the power 2.34. theoretically, this exponent should be 2.5 bond, 1961 . power d is directly related to mill speed in r.p.m., or, fraction of critical speed over the normal operating range.

  • charge behaviour and power consumption in ball mills

    fig. 13 shows the specific power d for ball fractions varying from 0% fully autogenous to ball only or fully ground out . the specific power curves for all the cases with ball fractions <80% are very close together.

  • how to calculate power consumption in ball mill

    calculation of the power d of dry multicompartment ball mills 225 the mill load that is the volume of charge in the mill is the principal determinant of. get price; calculate specific power consumption of a ball mill.

  • calculating power d when sizing ball mills - grinding

    the power d is driven mainly by mill diameter and length, ball and slurry charge level, and rotational speed. but the slurry charge in an overflow ball mill doesn't change very much because most of the slurry occupies the void space in between the balls, so as the circulating load increases, the discharge rate also increases.
