Size reduction Solids and powder milling
Common powder milling equipment. High speed hammer mills (tip speed from 40 to 70 m/s) can allow to reach small particles sizes, below mm A universal mill is a derivation of the hammer mill with more sophisticated beaters as well as grinding tracks and sieves. Tip speed ranges from 40 to 100 m/s.

Energy recovery potential in comminution processes
heat losses as well as mass losses through evaporation. In the case of the Brunswick mill presented previously, heat loss elimination would increase the energy captured in the slurry to 99% of the input energy. This would drive the discharge slurry to a temperature of 42 mum energy recovery potential can be obtained through insulationC using Eq.

Ball mill Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
