The double-roll crusher model, first proposed by Austin et al. [15] and lately refined by Austin et al. [16], is based on the following assumptions: a) breakage of each size particle occurs independently of the other sizes, b) provided the roll diameter is large enough compared with the feed size and gap, the product size distribution depends ...

The load conditions in the roll crusher, however, are usually point to face or face to face load conditions, which cause a larger contact area and therefore a slightly higher breaking force to be considered by a conversion factor (Schmidt, 2011). The method shows good results, however, for single particle crushing and low comminution ratios.

It is important to note that the well-known ball mill model cannot be directly used for the roll crusher. In fact, the double-roll crusher operates in a different way than reservoir type of mills and therefore must receive a different treatment. In ball mills the particles have a residence time during which they suffer repeatedly breaks.
