Dry fine comminution in a stirred media mill--MaxxMill~R

摘要

A large-scale continuous stirred media mill called the MaxxMill~R system in dry mode was used to investigate the comminution characteristics. A limestone powder below 2 mm was used as a feed material. A statistical experimental design was prepared with the major influencing parameters of the MaxxMill~R, such as rotational speed of stirrer, feed rate and bead size. The fineness of the ground products obtained under various conditions of the MaxxMill~R and the corresponding energy utilisation have been evaluated and analysed. The results have been empirically con-elated with the operating parameters. In addition, product size-energy input relations can be described empirically, independent of the parameters used.
