Variables in Ball Mill Operation Paul O. Abbe®
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). Dry mills typically operate in the range of 50 -70 of CS and most often between 60 -65 of CS.

Effects of ball-milling treatment on physicochemical
Ball-milling at 400 rpm gave the highest surface area of 412 m 2 g −1 while higher rotation speeds decreased the surface areas due to agglomeration. Moreover ball-milling resulted in the emergence of amino- and hydroxyl groups on the surface which were observed by Fourier transform infrared spectroscopy and partial oxidation of the surface boron by the formation of B–OH groups was

Effects of Rotation Speeds and Media Density on Ground
Superfine ground calcium carbonate (GCC) produced by carbonate minerals is a widely used inorganic powder material. In order to get a finer GCC powder with narrow distribution span the effect of rotational speed and media density on ground GCC were studied by dry grinding GCC in a planetary ball mill under different rotational speed and various media density.
