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.

Blasting Principles - Orica

A device containing a small amount of explosive, a signal transmitter and in some cases a timing mechanism, usually enclosed in a cylindrical metal shell. It is used to initiate less sensitive or secondary explosives. Modern blasting relies on detonators for the safe and precise control of explosive energy release to achieve desired blast outcomes.
