Ball Mill Critical Speed
A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. ... Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of ...

Explosively driven air blast in a conical shock tube
An explosively driven conical shock tube was designed, fabricated, and tested in an attempt to achieve full-scale blast behavior using relatively small driver charges. The LLNL shock physics code ALE3D was used to predict the shock tube driver charge mass necessary to approximate a free-field detonation from a 1.5 lb charge of C4. …

1/48" twist and conicals | The Muzzleloading Forum
Jan 31, 2007. #1. I am looking to buy a 1/48" twist 50 caliber barrel that is 24" long with .005-.006 goove depth with the intent to shoot pure lead conicals and ball-ets from 240-385 grains. Does the 1/48" twist do well with this weight range of conical. I would expect at least 4" or less at 100 yards bench groups.

Round Ball vs Bullets
A .350" round ball, striking a snowshoe hare's head at 50 yards, with an impact speed of 1,400 to 1,500fps, will decapitate said bunny. A .22 RL won't do that with any bullet, nor will a .22 mag. with normal 40gr. HP's, even though it's impact speed is higher yet, with a very frangible bullet.
