### Backyard BallisticsSponenburgh Ball Mill

Ball Mill I built a Ball Mill. Of the type commonly known in the hobby as a "Sponenburgh Mill". I bought the book "Ball Milling Theory and Practice for the Amateur Pyrotechnician" by Lloyd Sponenburgh from American Fireworks News. Or was it Harry at Skylighter. Ball-mill power 108 kw. In the first stage 9.11 T. of minus 200-mesh material were produced per hour and 11.98 kw.-hr. were required for each ton of minus 200-mesh material produced. The classifier delivered 32 T. of sand per hour. The total feed to the mill was therefore 47.31 T. per hr. or 308 per cent of the original feed.
