A comparative study on the effects of dry and wet
2019-9-1 In terms of the energy consumption (EC) for a certain particle size distribution, several investigations reveal that in dry grinding the EC is around 15–50% higher than in a wet environment,,,.Ogonowski et al. (2018) conducted an investigation to compare wet and dry grinding processes in an electromagnetic mill.
