Ball Mill Drives - Mineral Processing & Metallurgy
When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque. These assume no greater than a 10% voltage drop at the motor terminals. V-BELT Ball Mill DRIVE V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less.
