Grinding Media Motion and Collisions in Different Zones

2021-2-11  The grinding media fillings analyzed herein ranged between 50% and 90%, whereby the technically relevant filling levels are mostly in the upper range of 70–90%. However, continuous operation of a stirred mill can result in axially heterogeneously distributed grinding media, causing lower local filling levels.

Effect of Operating Parameters on the Breakage

2018-9-24  One of the most energy-intensive processes for producing submicron range calcite is stirred media mill. In the present work, numerous operating parameters such as solid mass fraction, grinding media size, media filling ratio, and grinding time have been investigated using a vertical type stirred media mill. The results are evaluated on the basis of mean particle size, specific surface area
