volume of ball mill ball load

Ball Mill Loading Guide | Orbis Machinery, LLC.
Media and Product Ball Mill Loading Guide. (Percentages are based on total volume of cylinder) NOTE: With media load at 50%, voids are created equal to 20% of cylinder volume. These voids are filled when product is loaded into the mill. Mills can be loaded by volume or by weight based on product’s bulk density.
