Wet and dry grinding of coal in a laboratory-scale ball

Jan 01, 2020 The mode of grinding, wet or dry, has significant differences in grinding kinetics and the properties of the ground products. Breakage rates (first-order hypothesis) for wet grinding are faster than those for dry grinding when the solid concentration is less than 50 vol %

Wet Grinding of Coal in the Szego Mill: Limiting

May 16, 2007 A dynamic wet-grinding model recently developed for the Szego Mill is reviewed. Use of this model allows a priori predictions of limiting performance for all design and operating variables in the “paste grinding” regime, i.e., at relatively high solids concentrations which are optimal for wet grinding in the Szego Mill
