Cement mill  Wikipedia
Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size  mills including a roller press are mostly singlechambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker

Physics Questions
If the speed of the material just before it strikes the plate is equal to the speed of the material just after it strikes the plate, determine an equation for the mass flow rate of the material, based on the horizontal force readout on the sensor. Ignore friction with the plate. Hint: This can be treated as a fluid flow problem. Problem # 17

Milling Speed and Feed Calculator 
Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.

Ball Mills  Mine Engineer.Com
The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being

INNOVATION NEWS Mills and GMDs 
SAG mills with a rated power of up to 35 MW. As well as ever larger SAG mills, ball mills are also expanding in size. In the late 1990s the trend moved towards using GMDs to power these larger ball mills, as well as using the drive to vary the speed. GMDs quickly moved from 20' ball mills, expanding to 24, 25 and then 26' mills. In early

Ball mill  Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

Rod mills, how they function  Mine Engineer.Com
The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size.
