The mill used for this comparison is a 4.4-meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour. . The starting torque characteristic of this type of ball mill is not linear. Figure 2 shows the graph of mill speed versus torque requirement: Figure 2. The graph.
mands of high torque - direct drive systems and drive systems using standard torque motors with Airflex clutches which replaced them. Because of the large thermal loads associated with mill start-up, the use of VC clutches are recommended. Clutch Selection. The required clutch torque is calculated from the power rating of.

The drive sets the milling drum into slow rotation and the bed of milling media is thus activated, i.e. the balls are lifted and then impact back against the bed. Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out.

Oct 25, 2011 . Horsepower (HP). A measure of the rate at which work is done. 1 HP = 746 watts = 33,000 lb-ft/min = 550 lb-ft/sec. Power (kW) = HP x 0.746/eff. Example: What is . Motor Loads. Constant torque/Variable HP. Torque independent of speed. Not the best VFD application. Rotary/screw compressors. Ball mills.
Many times when machinists look at cutting tool speeds and feeds, they are often misled into believing that they should be concerned with horsepower. The real driving force is not horsepower, it's TORQUE!
