Ball Mill Loading - Wet Milling - Paul O. Abbe

Charging a Wet Mill – The general operation of a grinding mill is to have the product impacted between the balls as they tumble. Unlike dry milling, wet milling is more straight forward and more forgiving in terms of charging the product. As with dry milling there should be at least 25% liquid to fill the void space plus a bit more...
