The planetary mill provided sub-micrometric alumina powder in just one hour, having a better breakage than the attritor in 6 hours and the vibratory mill in 24 hours. The alumina ground by the planetary mill had a broad particle size distribution (a span equal to 2.00) while vibratory mill provides the narrowest (a span equal to 1.40).

Attrition mills are more appropriate for "mid-range" size particles. Such mills utilize 3–10-mm 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 1/64–1/8 in. Ottawa silica from Canada.
