Ball Mill Scale-up by this method is known as collision energy based population balance model.The appropriateness of this model is shown for 38-cm ball mill. Comminution in ball mills account for a significant amount of power consumption in mineral processing plants.
Abstract. The power consumption of stirred-media mills was studied using an approach developed from work on stirred reactors. Evaluated were the relationships of factors such as stirring speed and impeller and tank dimensions on the torque required to rotate disc and pin impellers immersed in .
The scale-up and simulation model used here is based on the population balance modeling technique using the Herbst & Fuer- stenau scale-up procedure for ball mills, adapted for vertical stirred mills.
Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated.
contributed to an increased rate of production and reduced specific power consumption in the grinding operation and wear rates. Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill.
