Given W, W i and F 80, one can calculate the product size, namely, P 80. This is one of the simplest models to predict the ground size. Traditionally, Eq. (1) has been the main tool to design new mills, even though it can only predict one point of the product particle size distribution, P 80. Then, during, Population Balance ...

[Note: The particle size shown on Figure 3 and also used for calculations in this paper is defined as the minimum particle diameter of a given size band. For example, a particle that passes a 150 mesh screen (105 microns) but is retained on a 200 mesh screen (74 microns) would actually have a diameter between 74 microns and 105 microns.

This means that in operation, the pebble crusher remains in an intermittent operating state. The size of the ball mill is slightly undersized, which could explain why the circuit is unable to reach the designed product size (115 µm). Furthermore, the operating capacity of the ball mill has reached 90% capacity, running at near full load.
