WhatsApp: +86 18203695377WEBJun 1, 2009 · Abstract. Breakage rates of coarse particles in ball mills generally follow nonfirstorder kinetics and the distribution products from batch milling are often characterized by significant contributions of abrasion besides breakage by impact, which are not well described using traditional size–mass balance formulations.
WhatsApp: +86 18203695377WEBJul 1, 2010 · In the theory of ball mill, water results in softening the cellulose, which binds the microfibrils; it still needs some shear forces in order to break the bonds. Size reduction is a process in which particles are broken into smaller pieces. Generally, there are three processes involved: (1) cutting, (2) abrasion, (3) crushing.
