Feb 25, 2004 · The shape of the bowl of the 10-l Fielder granulator (used with the insert on the RHS) was different than the other granulators; filling this granulator to the tapered part of the bowl required a bed-height to diameter ratio of Z/D=0.416. As shown in Fig. 14, scale-up from the 2- to 10-l machine was achieved with a scaling index of n=0.5.
