#### A Modular Dynamic Simulation Model for Comminution Circuits

The multisegment flow model schematized in Fig. 1, which is composed of a transport delay Vd followed by three continuously stirred reactors (CSTR) with internal classification, allows simulating both rod and ball mills. The first two CSTRs are identical. Their fixed volume Vf is expressed as a fraction of the grinding media interstitial volume.
