awet grinding stirred media mills

2) grinding media (1 mm) on wet grinding of talc (d 50=6 m) powders to produce submicron particles was performed in a lab-scale (750 ml) stirred media mill. experimental results were evaluated based on the average particle size (d 50), specific energy consumption (kwh/t) reduction ratio and the specific surface area (m2/gr).
