  • Charge behaviour and power consumption in ball mills

    · The specific power consumption for these two ball shapes is shown in Fig 16 For N≤75% there is no change in the mill power draw This occurs because the center of mass of the charge is little changed by the particle shape at these speeds At intermediate speeds, the power draw for the noncircular balls falls off rapidly This reflects the· If P is less than 80% passing 70 microns, power consumption will be; Ball Mill Power Calculation Example #1 A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns) The required product size distribution is to be 80% passing 100 mesh (149 microns) In order to determine the powerBall Mill Design/Power CalculationCompiled model to determine the power consumption of the electric drive of a ball mill The modeling work mill with no load and during grinding the ore The simulation results are confirmed byModeling of power consumption of ball mill | Request

  • Ball Mills an overview | ScienceDirect Topics

    In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ground cement less still The vertical mill has a proven track record in grinding blastfurnace slag, where it has the additional advantage of being a much more effective drierOf course all the ball mills operate in slurry pooling conditions but with low ball charge it will be larger than before so it will affect the P80 (Ball mill Product 80 % passing not circuit product) badly and it will increase He had mentioned adding water to classifier underflow; this work will reduce slurry density With low slurry density (under 60% solid percentages) because of moreBall Charge and Grinding Efficiency GrindingMill 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 Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degreeOptimization of mill performance by using

    the application of ball mill power from fine (minus P80 product size) to coarse material, circuit efficiency is increased and overgrinding is decreased The other factor that determines overall circuit efficiency is how well the power that is applied to the coarse material grinds it This is affected by design and operating variables like the media sizing and mill percent solids From circuitThe power predictions for ball mills typically use the following form of the Bond equation: = () SAG mills use a ball charge of 8 to 21% The largest SAG mill is 42' (128m) in diameter, powered by a 28 MW (38,000 HP) motor A SAG mill with a 44' (134m) diameter and a power of 35 MW (47,000 HP) has been designed Attrition between grinding balls and ore particles causes grinding of finerMill (grinding) Wikipedia
