Measuring the impact velocities of balls in high energy mills

Abstract A simple methodology for the experimental determination of impact velocities in ball mills used for the synthesis of nanophase materials is proposed. The impact velocity of the balls relative to the vial wall is determined from the indent size. A model correlating velocities with indent radius is described. Velocities were determined for the Spex mill (1.8–3.3 m s −1 ) and for a ...

Robust Model Predictive control of Cement Mill circuits

The present work considers the control of ball mill grinding circuits which are characterized by non-linearities and disturbances. The disturbances are due to large ariationsv and heterogeneities in the feed material. Thus the models obtained by simple tests on these mills are subject to large uncertainties which may result
