Attrition mills are more appropriate for "midrange" size particles. Such mills utilize 310mm media to produce material ranging in size from approximately 1 to 10 microns. The first "small media" mill was introduced about 60 years ago. It was named a "sand mill" because it used 1/641/8 in. Ottawa silica from Canada.

Silica is a highly refractory material, this lowtemperature glaze should not have been able to dissolve that much of an addition without cost to the gloss, melt fluidity or transparency. But none of these has happened and the reason is, in good part, because of the finer particle size of the silica powder: 45 microns (or 325 mesh). It is ...

Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.
