Ball Mill Drives. We can provide all elements of a mill drive system as a fully optimised solution to suit your process exactly, or individual mill drive gearboxes, girth gears, pinions and couplings as required.
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 ...
Stepover is the same thing, it refers to the amount of overlap there is between passes. 40% is the default which is good for most general pocketing and roughing passes (when carving 3D objects). When making finish passes, you would reduce this number to 10%, especially when using a 1/16″ ball nose end mill .

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.
