### Ball Mill Explained

If a ball mill uses little or no water during grinding, it is a ‘dry’ mill. if a ball mill uses water during grinding, it is a ‘wet’ mill. a typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube.In mineral processing design and operations (second edition), . 8.3.1 rod mill charge. 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.

### Key Considerations When Selecting A Mill Lining System

Jan 27, ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% - 40% of mill chamber volume. to effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill’s.Jul 03, the average particle is subjected to an action similar to many sets of rolls in series, before it is discharged. because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. the voids (or interstitial space) within a rod load are approximately half those in a ball mill.
