This study investigates the influence of some chemical additives such as methanol, ethanol, sodium oleat, chloroform and sodium hexametaphosphate (SHMP) on the dry fine grinding of calcite (X50= 33 µm) using a stirred media mill. The experiments were carried out by a batch operation, and the change in colour properties (Ry, whiteness and yellowness) of calcite powder. The results showed that th...

This study's aim is to investigate the wet and dry grindability of K-feldspar in a narrow grain size range stirred ball mill. In evaluation grinding process, full factorial design was used observe effects selected parameters on dependent variable. On grinding, parameter such as diameter, stirring speed, time, interstitial filling ratio were investigated. Experimental results showed that can be ...

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

The relative motion and collision between grinding media in a wet-stirred accelerator mill are modelled using the discrete element method (DEM) coupled with computational fluid dynamics (CFD). local average normalized velocity profile is employed to divide chamber into four volumes, which facilitates analysis of stress energy distribution. filling levels, distributions, distributions efficienci...
