Mill is the ball milling model that is based on standard austin’s models (eqns. (14) and ) and takes into consideration the breakage parameters as does the moly-cop. it is mentioned that the mill model does not take into consideration the operating conditions (e.g. mill diameter, ball filling volume and mill speed) and a different unit model.

Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. it is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. figure 2 shows that there is no linear relation.
Very often takes place in a ball mill [3]. the mass and the balls are additionally agitated by a shaft with arms, operating at a variable rotation speed. during refining, the mass can also be recycled through the ball mill, thus going through a thick layer of balls, which are kept in continuous movement and forced to bounce against each other.
