Understanding Size Segregation in Tumbling Mills SpringerLink
122· Size segregation is a desirable as well as nondesirable phenomena depending on the objective of unit operation. It is nondesirable when mixing is required in unit operations such as tumbling mills, powder mixers [ 2, 40 ]. Size segregation is desired when separation or material recovery is the objective of the operation [ 14, 42, 45 ].Evolution of a generic, dynamic and multicomponent tumbling mill ,111· The goal of dynamic tumbling mill modelling is to improve design and mill sizing for varying feeds within the dynamics of a milling circuit, apply the model to the design and application of control systems, improve energy utilisation, reduce operating costs and increase productivity.
