This study presents an approach for targeted comminution of component mixtures within a wetoperated stirred media mill. In the first step, a general understanding of the interactions between individual components on the grinding result with mixtures could be gained with basic experiments and following our former research work. In particular, a protective effect of the coarser particles on the ...

The average roughness (Ra) values of particles increased from nm to nm upon increasing the grinding time from 2 min to 16 min. Due to these findings, it can be suggested that lignite samples became rounder with increasing grinding times, and roughness analyses made in a 10 × 10 μm surface area with an Atomic Force Microscope (AFM) ind...

1. Fine grinding in the mining industry. It has been estimated that approximately 2% of the world's energy usage is applied to mineral comminution, and around a quarter of this is used specifically in metalliferous ore grinding [1] where it is typically the most energy intensive set of operations [2].The purpose of comminution in ore processing is to reduce particle size in ...
