The global aim of the present work is to apply the previously described model to the breakage of urea in large-scale double-roll crushers from an industrial granulation plant. To do this, experimental data from an industrial double-roll crusher belonging to a urea granulation circuit under normal operation were used.
Predictions for five types of crushers: jaw crusher, cone crusher, gyratory crusher, impact crusher and double roll crusher were presented. The breakage method used is based on facture of particles using geometric rules for progeny generation and estimates of the forces applied to the particles as they flow through the crusher.
