✦ Synopsis

A mathematical analysis of the steady-state behavior of a continuous granulator is presented. The analysis is based on the following main assumptions that granules grow at a uniform rate, independent of granule size, and that the crusher is the main source of new granule formation. Special attention is given to the balance of the number of granules in the process loop, and the role of the crusher which receives the oversized granules from the sieve is emphasized. Some numerical results from the model developed are given; these are the effect of the granule size of the crusher discharge stream on the recycle ratio of granules (the ratio of the recycle rate to the production rate), and the effect of the granule size of the crusher discharge stream on the fraction of the on-sized granules to be recycled.
