According to Figure 1, the dynamic model of the ball mill is where is the rotation resistance coefficient of the drive motor, is the friction torque, and the rotation direction of the ball mill is determined by the sign function sign().. When the rotational speeds of the clutch are synchronised, i.e., =, the clutch no longer slips. The dynamic model can be written as follows:
product of the mill rotational speed and the torque applied, so there is a lineal dependence; on the other hand, the centreof gravity of the charge is shifted withspeed, creating a non-lineal dependence. The overall power draw versus mill speed dependence results in a …

the motor must be installed and operated in strict accordance with the outline drawing, motor nameplates and these instructions and must not be altered or modified in any unauthorized manner. During these installations and operation of motors in heavy industrial applications there is a danger of live electrical parts and rotating parts.
Typical motor speeds are either 4 or 6 pole, i.e. 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if required by the process. A six pole motor will be larger but will have a …

higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings. For gearless drives, motor torque output at the maximum desired operating mill speed and ball charge volume has to be determined. Primary Mills: Torque Output (by Motor) vs Torque Demand (by Mill)
New India offers an entire range of World Class DC Motors with Laminated Yoke in frame sizes from 80 to 710. Motors are designed for applications having constant and variable speed requirements. We not only offer a complete range of standard motors but 50% of the motors produced are specially designed based on application requirements.
Effect of ball diameter size on mill power draw The mill power draw for each mill run was determined from the voltage required by the mill motor average voltage and torque. To take a closer look at the relationship between the power draw and the ball diameter, Figure 4 below was plotted using data from 4 …

The poles of the gearless or synchronous motor (also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.
