First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.
Milling Horsepower Calculator. Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.

ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and grind it at the same time by sweeping hot air through the mill.
