Model of unit processes

F is the fraction of the circumference of the two chambers which is open between them. 

In the same example, the total amount of the compound was 1.4 kg. On the assumption that the average density of elastomers and other additives is 0.98 g/cm and that of carbon black is 1.88 g/cm [29], the density of the compound is calculated to be 1.17 g/cm. The total volume (V ) was then 1,200 cm. Even under 0.24 MPa of ram pressure, the actual volume of the compound changes with the progress of mixing. However, the compacted volume may be taken as a reference equal to 1,200 cm. The powdered rubber compound is macroscopically uniform in composition. Therefore, the composition of the material in and the rest of the volume are the same. Because the material in is compacted, it may be compared to the total compacted volume of the compound, i.e., = 0.146V-J.. If all the rubber particles 

During the dispersion process, not only the rubber particles but also the carbon black agglomerates break. Therefore, the mechanism of breaking of carbon black must be included in the dynamic model of mixing. However, this aspect is relegated to the future refinement of the model.
