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.
Ball Mill Application and Design Paul O Abbe.Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of to 1.5. The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.
