Sep 10, 2017 This is an advantage of the new classifier compared to gravity fed classifiers. Moisture levels below 0.5 usually do not cause a problem. Dry grinding generates friction heat in the mill, which reduces the moisture level. Of course, care must be taken to avoid condensation in the classifier and conveying system at start-up from cold temperatures.
