Critical rotation speed for ball-milling - ScienceDirect
Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter.
Ball Nose Milling Strategy - Helical Solutions
) - To be implemented when using a ball nose end mill that is utilizing a ADOC that is less than the full radius of the ball. This can be done using the chart below (see Figure 2) that represents some common tool diameters & ADOC's at 15º tilt angle or by using the traditional calculation (see Figure 3).
Calculate and Select Ball Mill Ball Size for Optimum Grinding
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where Dm = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.
Ball End mill speeds - practicalmachinist.com
Approximating pi allows the simple formula of 4 x cutting speed (sfm) / diameter (inches). For form cutters like your ball endmill, the recommendation was to cut that rpm in half. I think part of that guidance was to skew towards longer cutter life for a more expensive cutter.

Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length. Vertical mill is used in grinding material at smaller particle sizes, which is used after ball mill.
