how to decrease motor ampere of ball mill

  • How to Convert Amps Volts Watts Easily

    The difference between volts and amps is that amps measure the volume of electrons flowing while volts measure the pressure causing them to flow. Watts Amps and volts combine to create watts a measurement of the amount of energy being released. In the case of the garden hose this would be the amount of water flowing.

    What causes a motor to draw higher than normal amps

    2015-6-4 · 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.

    Discussion The rotational speed grows as the motor speed increases. As the ball mill uses more kinetic energy to crush the coarse sample which results in a rise in sample weight. At the 45 motor speed the efficiency was 23.7 while at the 100 motor speed the efficiency was 30.3 . Thus the efficiency of the ball mill increases as the kinetic energy of the ball mill increases.
