The type of unit slightly affects the algorithm for applying transformation
matrices:
• in steady-state units: the input distribution is copied to the output, then the
transformation matrix is applied to the output;
• in dynamic units: the input distribution is mixed with the holdup, then the
transformation matrix is applied to the holdup, after which the outputs are
calculated.
5.4 Simulation Examples
In order to test and validate the developed algorithms for lossless calculation of
the distributed parameters of the solid phase, several model experiments were performed. The flowsheet of one of the simulated processes [53] is presented in Fig. 17.
It is a typical grinding process often used in the mineral processing industry [19,
50]. It consists of three successive crushing stages: pre-grinding of coarse material,
separation and further grinding of large fractions, and the final crushing in a closed
circuit.
