Micromechanical aggregate properties are correlated with stress conditions during the dispersion process in a stirred-media mill. The fracture energy distribution of the aggregates measured via micro-compression tests is compared with the stress energy distribution in a stirred-media mill determined by CFD-discrete element method simulations and by an analytical model. The simulations are ...

slurry feed rate, the media size, and the media density (Orumwense and Forssberg, 1992; Sinnott, Cleary and Morrison, 2009). As a basic rule, the most advantageous orientation is the one that results in an equal media distribution within the mill chamber (Stehr, 1988). A more recent trend in stirred mill classification is based on the tip speed ...

Charge Media Distribution Inside Ball Mill

Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
