A specific energy-based ball mill model: From batch ...

A specific energy-based size reduction model for batch grinding ball mills was reported in a previous paper (Shi and Xie, 2015). A discharge function modified from the Whiten classification efficiency equation has been incorporated in the size reduction model to extend its applications from batch grinding to continuous operation.

A direct approach of modeling batch grinding in ball mills ...

The charge motion of the experimental mills was simulated by the DEM simulation code using the parameters presented in Table 1.As seen in Table 1, the predicted mill powers are in good agreement with the measured mill power data.The computed impact energy distributions are presented in Fig. 2.Generally, the total number of impacts in the 25.4-cm mill is less than that in the other two mills.

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

Mill power draw models - SAGMILLING.COM

Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.
