charge should always be 50%, material charge will vary from 25% to 40% or more in some cases such as when grinding 100% homemade airfloat charcoal. The best way to tell if your mill is properly charge is to listen to it after about 15 minutes of grinding. You should hear a continuous cascading sound that is fairly loud. If the mill seems quiet

Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further. However, close packing of the charge rarely occurs and an operating bed ...
