Experimental study of residence time distributions of ball-mill

Residence time distributions (RTDs) were estimated by water tracing in a number of wet overflow ball mills (diameters 0.38 to 4.65 m) producing dense, coal-water slurries. In open-circuit mills of 0.38 m diameter and various length-diameter (L/D) ratios, the mean residence times of solid were also determined from measured mill holdups. …

What Is the Difference Between Dry and Wet Grinding?

Efficient particle size reduction: Wet grinding can reduce particles to a smaller size compared to dry grinding. No dust: Wet grinding does not produce dust, which reduces the risk of contamination and improves worker safety. Cooling effect: The liquid used in wet grinding acts as a cooling agent, which prevents thermal damage to the material.
