The influence of pre-fibrillation via planetary ball milling …

A planetary ball milling was applied as a pretreatment of chitin powder to prepare precursors for chitin nanofiber (ChNF) production. The study aims to examine the effects of ball milling conditions (dry milling, and wet milling in neutral and acidic aqueous medium) on the degree of pre-fibrillation of the ChNF precursors and the characteristics of the resulting nanofibers. The results showed ...

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. A ball mill ...
