Please find below two calculators for sizing mills using the Bond and Rowland methods: Ball mill sizing: Calculator for ball mill(s) in a single stage circuit. Rod ball mill sizing: Calculator for rod mill(s) as first stage of the circuit and ball mill(s) as second stage of the circuit.

In multistage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill.

Low aspect mills are best suited to lowtomedium competent ores, while high aspect mills are more commonly used for competent ores either as singlestage circuits or autogenousball mill twostage circuits. The larger diameter and short length provide better impact breakage for the competent ore.
