    Dry grinding in planetary ball mills: Evaluation of a ...

    Planetary ball mills at laboratory scale are widely used for grinding and alloying processes. However, in contrast to other mill types, no applicable mechanistic model exists to describe the stressing conditions and their effect on particle breakage, so that processes are empirically evaluated so far.

    I made my first scale model on a roll of teletype paper tape (anyone remember that stuff?) On this 1inch tape, my Sun was the size of the tape 1 inch in diameter. It all started out well. Mercury was only about 31/2 feet from the sun and Earth was almost 9 feet from the Sun. What I didn't bargain for was that Pluto was 354 feet down the tape!
