Fine wet grinding of an alumina hydrate in a ball mill

Abstract An experimental study on fine wet milling of an alumina hydrate in a batch ball mill has been carried out. The effect of experimental conditions of grinding have been determined showing that the size reduction rate is mainly affected by the fluidity of the slurry. This is related to the amount of fines in the load, the viscosity of the medium and the persence or not of chemical additives. The size distributions of comminuted particles exhibit a self-preserving behaviour as a function of time and can be properly described by a Rosin-Rammler-Bennett equation.
