Exploring ball size distribution in coal grinding mills
· K = 15.21058 when mill dimension is in metres. D & L are mill dia & length respectively. N c is mill speed as a fraction of critical speed. J is the ball filling fraction. ρ charge is the overall charge density calculated as follows: ρ charge = total coal mass + ball mass

How to Size and Select Ball Screws: An Engineer's Guide
Because ball screws are a bearing system, they’ll need some type of lubrication to avoid metal-to-metal contact of the balls in the raceway. While the lubrication choice can be either oil or grease, it’s advisable to avoid solid additives (such as graphite) as they will clog the recirculation system.

Modelling: Transfer size limits
For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of 7.5 MW of power draw available for a total of ratio of 10:15 (1:1.5). The software uses the particular power model (Bond/Barratt, Morrell Mi, etc.) to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill power (1:1.5 in this example).
