Simple attrition (multibead) and impact + attrition (ball + beads) millings afforded the smallest (and similar) d50 in agglomerated (14 µm, 15 µm) or deagglomerated form (7 µm, 8 µm). The impact (ball) and attrition + impact powders (beads + ball) had a significantly higher d50.

Attrition mill is a principle in which grinding balls are moved by rotating the impeller, and biomass is crushed by the impact and shear actions exerted by the grinding balls. Crushing and dispersion times are significantly faster than those of general ball mills. In particular, attritiontype mills can be rather easily scalable

Media sizes for coarse grinding in heavyduty ball mills range from about 80 mm maximum to 20 mm and for medium to fine grinding mill on down at about a minimum of 8 mm. Below about 16 mm, removal of the ground mixture becomes increasingly difficult and the practical media size limit is around 12 mm. Grinding capabilities of all these small ...

A ring and ball mill consists of two types of rings separated by a series of large balls, like a thrust bearing [20], that crush the material in between two particles. The attrition mill mechanically reduces solid particle size by intense agitation of a slurry of material being milled and coarse milling media [21].
