  • 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 maximum and finally the type of circuit open/closed

  • Ball Mill Critical Speed

    A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical

  • What it is the optimun speed for a ball mill

    Oct 19, 2006· Congratulations on your ball mill! You'll want to further reduce your motor speed by 3:1 to mill more efficiently. Right now, your RPM is just slightly under the speed where the media won't do any . The optimum speed for your jar to turn is around 90 RPM like Frozentech said.

  • Factors Affecting Ball Mill Grinding Efficiency

    The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different

  • What causes a motor to draw higher than normal amps AMP

    Because this motor draws too high of amps we can only run 2 motors/pumps at a time. We have pulled the pump and trimmed the impeller to reduce pumping capacity to lower the amp draw but it did not change the amp draw at all. The talk now is to swap motor "A" for motor "C" and see if the amp problem follows the motor or stay with the pump.

    Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

  • What's causing your high motor current Plant Servs

    Feb 23, 2018· The torque capability of a motor is proportionate to the square of the magnetic flux level. For example, if the winding flux is 10% lower than the design flux, the torque capability of the motor will decrease to about 81% (0.9 × 0.9 × 100 = 81) of rated. A motor with a power rating of 100 hp would therefore behave as if it were designed for
