Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.

Ball mill is a versatile grinding mill and has a wide range of applications. The mill can vary in size from small batch mills up to mills with outputs of hundreds of tons per hour. They are the most widely used of all mills. Roller mills. Roller mills are basically of two distinct types.

lb), occupying 34 percent of the mill volume. Balls are used that represent a fully graded charge based on constant wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent ball charge. The drive shaft is torque-metered and records once per second. Drive losses (a roller bearing between

Square planetary ball mill shares similar parameters to the half-sphere ball mills. Different from the compact design, the square planetary ball mills have the space to host larger grinding jars, enable it to be used for materials synthesis on a large scale. The mill can also host 4 jars running the mixing and grinding.
