Ball Mill Volume Loading

Once the quantity is finally determined you can simply load the mill with thetotal amount of solidsduring the initial mill charging with proper solids loading of about 25 solids red the grinding media gray will always have product to impact between the pieces of media with too low a solids loading the media will stike themselves resuling in ineffective millign and increase media and mill wear
