The running back was on the field for 61 percent of the offensive plays, with Tyler Allgier at 35 percent and Cordarrelle Patterson at 13 percent. Plus, Smith noted, Robinson's presence in and of itself can be a factor for the offense. "Sometimes, his impact away from the ball can open things up," Smith said in his press conference.

We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Do not mix through screens, mortar and pedestal, ball mill or any other method involving friction. Preferable method is the diaper method, whereby ingredients are placed on a sheet of paper and mixed by pulling up opposite corners of the paper so that the composition slides over itself. Flash will detonate unconfined if ignited, so use great ...

Remove the tape, use a video camera to record the burn, and count the number of frames it takes from ignition to flame coming out the other end of the tube. I test a small sample of powder every hr during milling, and consider my powder to be "liftworthy" if it burns within a few tenths of a second of 2sec or less.

Ball milling is more dangerous method of mixing pyrotechnic compositions as it produces large amounts of shock and friction. Lead balls or any non sparking grinding media are used inside the ball mill to 'crush' the ingredients, non sparking grinding media are essential for safety when preparing pyrotechnic chemicals such as black powder.
