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!

speeds are variable, determine the horsepower to be transmitted at .. H slitters. M non-reverse group drives M non-reverse individual drives H reversing drives. H wire drawing & flattening M wire winding machine. M. Mills Rotary Type ball. M .. required horsepower for the chain pitch as calculated in step 3 engineering.
