When F is the size in microns which 30 per cent of the new ball mill feed passes, P is the microns which 80 per cent of the last cycle sieve undersize product passes, and P1 is the opening in microns of the sieve size tested, then ball mill work index Wi is calculated from the following revised (1960) equation:
Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS.

Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
Planetary ball mills share the same design as other basic ball mills – a grinding jar filled with media and rotated on its own axis. But their unique design takes advantage of centrifugal force and the Coriolis effect to grind materials to a very fine or even micron size. These forces come into play as

End Mill Feeds and Speeds. The most important aspect of milling with end mills is to run the tool at the proper RPM (revolutions per minute or spindle speed) and IPM (inches per minute or feed rate). We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.
Variables in Ball Mill Operation. ... This reduced to CS = 265.45/√(R-r). Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS. Below 50% CS too little energy is imparted to fracture particles and above 70% CS the media will start to cataract or be thrown from the top of the pile of media with each ...
