I Attrition bead mill The model used for the simulation of attntlon grinding is the basic kinetic model. in where the first order breakage hypothesis for particles is assumed (Arbiter and Brahny (1960). This assumption is accepted by many authors. by example Austin et al. (197In2. 1976). Heiskanen (1978).
