2-1/2 lbs. fireworks chemical mill grinding media balls
My apologies for the strange title. It’s made up of keywords that people who use this product might use when searching for it. To clarify, I’m selling 7 two-and-a half-pound boxes (Photo #1) of the special, high-density industrial milling balls used for grinding and mixing the chemicals used in rocketry, pyrotechnics, and many other industries.
To clarify what you see in the photo, I've placed 2-1/2 pounds of the balls in a 1-pint measuring cup, and as you can see, the total volume of 2-1/2 pounds is a little over one pint.
These high-tech industrial milling balls are specifically designed to maximize a ball mill’s speed and efficiency. Each ball is made in the form of a small sphere (1/2†diameter) with a cylindrical waist band. As the author of the currently popular book, Amateur Rocket Motor Construction, in my own experiments I found that, when substituted pound-for-pound for the brass pellets recommended in the book, they reduced the milling time for a batch of chemicals by 40%! To clarify, a 12-hour mill run with brass pellets was reduced to about 7 hours, and a 6-hour mill run was reduced to 3-1/2 hours.
Made of a special high density (90% alumina) ceramic, they are much harder than brass, they are very heavy, they will never corrode, and they will last for many many years. Important note. Though they are often used in pyrotechnic milling, they are ideal for any application that requires a high density, high efficiency milling ball.
