This article studies a continuous rotary mill for the cement industry. Specifically, a model is used population balance, where a law constant wear is the constitutive equation, in order to obtain: the distribution mass of the ball in mill, the total consumption of steel of the balls and the inlet flow of balls for the recharge in steady state. The database was obtained applying the Ball test marked industrial scale in a rotatory mill of the Argos SA company.
