N2 - Granulation is the process of forming large aggregates from fine particles using a high shear mixer. This method is used in several industries from pharmaceuticals to chemical and fertilizer production. This research will study the effect of four process variables: speed of mixer rotation in the range 100 to 200rpm, powder bed mass (25 to 40g), mass of the initial nucleus (0.6 to 2g), and binder viscosity (water, CMC solutions with concentrations in the range 0.5 to 20g/L) on single nuclei growth kinetics in low mixing devices. The powders under study are: lactose, tea, sugar, starch, and limestone. The results show the initial size of nuclei, the initial mass of the powder bed and binder viscosity and speed of rotation all influence the rate of nuclei growth.
