Granulators size stratification

Figure 12.7. Rotating dish granulator applications and performance (Sherrington and Oliver, 1981). (a) Edge and face view of a dish granulator, diameters to 25 ft, Froudc no. n2D/gc = 0.5-0.8. (b) Stratification of particle sizes during rotation, (c) Typical applications of dish granulation (Dravo Corp.). (d) Capacity and power (Dravo Corp.). (e) Performance on cement kiln feed.

The starches are differentiated by the size and form of the granules, by the presence or absence of stratification and of a hilum, and lastly by the isolation or grouping together of the granules.
