Ball Mill Motor Selection

A common cause of motor failure is problems with the motor windings, and the solution often is to rewind the old motor.Because it is economical in terms of initial cost, rewinding of motors is very common particularly for motors of more than 10 horsepower.However, the motor rewinding process often results in a loss of motor efficiency.

Calculate And Select Ball Mill Ball Size For Optimum

The ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the target p90.Based on his work, this formula can be derived for ball diameter sizing and selection dm 6 log dk d0.5 where d m the diameter of the singlesized balls in mm.D the diameter of the largest chunks of ore in.

Technical And Commercial Benefits Of Gearless

As a result the motor does not have a separate motor rotor and thus no separate motor bearings.The number of poles is based on the required speed of the mill.The motor operates with typical frequencies from zero to about 6 hz.In general, the bigger the mill diameter, the lower are the mill operating and critical speeds.
