(PDF) Modeling of an industrial double-roll crusher of a urea
Breakage in double-roll crushers ('once-through' equipment) occurs instantaneously while the material is pulled into the rolls, thus all the particles pass through the set gap [10]. 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 ...
