The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.

The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.

The present work seeks to establish a relationship between Bond's work index (W i), indexes n (uniformity constant), and K (rate constant) from the theory of grinding kinetics so that by collecting and analyzing only bygone data, a decision could be taken out about the size of the mill. 2.
