using the Kuz-Ram distribution a different feed size distribution was used to represent each ore type from the same blasting conditions. It was shown that there is a relationship between the value of the constant representing the ore type in the Kuznetsov equation and the value of d50 in the product size distribution of the gyratory crusher.

The breakage model is used to estimate the product size distribution after each compression for each crushing zone, referring to the zones shown in Fig. 7. The module predicts the crusher output product and the spread of product size distribution in each zone, where the spread is the slope of the cumulative curve.

Black-box models consider a crusher as a transformation between feed and product size distribution. They predict the product size distribution from the feed size distribution, breakage characterization and machine operating conditions. The Whiten cone crusher model (Whiten, W.J., 1972) is the most widely used example in this class.
