Large-size media are required to fracture particularly hard particles in the mill charge; smaller media fill the voids and promote finer grinding. For continuous grind applications or batch mill, attending to media volume is advisable - maintaining a 40-45% media charge (of mill volume) and keeping throughput constant will provide best results.
The choice of grinding media The choice of grinding media will always depend on the material to be ground. You need to assess its granulometry and the grinding process. You also need to look at the relative importance of the wear mechanisms in the process.

When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product. Charging a Dry Mill – The general operation of a grinding mill is to have the product impacted between the balls as they tumble.
When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product. Charging a Wet Mill – The general operation of a grinding mill is to have the product impacted between the balls as they tumble.
When charging a grinding mill, the standard practice is to dump tons of balls into the mill at once and replace them somewhere between once a shift and once a week. It's an inefficient practice that wastes energy, impacts product particle size distribution and risks breakage of mill linings and grinding media.
