Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS. The formula for critical speed is CS = 1/2π √ (g/ (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√ (R-r).

The BHI-FW ball mill product line has standard capacities from 10K to 210K lbs./hr. There are close to 500 MBF mills in operation beginning in the 1970s and there are 590 ball mills, since the early 1980s. Typical Fineness. MBF Mills – 70% passing 200 mesh. Ball Mills – 85% passing 200 mesh. MBF Pulverizer Design Features.
The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at critical speed.

Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.

The point where the mill becomes a centrifuge is called the critical speed, and ball mills usually operate at to of the critical speed ball mills are generally used to grind material inch and finer, down to the particle size of to microns to achieve a reasonable efficiency with ball mills, they must be operated in a closed
Mill Speed is one variable that can often be easily changed with a variable frequency drive (VFD). The starting point for mill speed calculations is the critical speed. Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Ball milling is one of the few unit operation that improves
