Ball Mill Loading - Wet Milling - Paul O. Abbe

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 to insure the balls are striking product and not each other. Of course the surface tension of the liquid used will greatly affect the...
