| Abstract: | For wet high-shear granulation, there can be a considerable variability in product quality in terms of the size, binder content, porosity, and appearance. Using the same equipment and feed material, it has been shown that such variability can be reduced by optimising the operating protocol. The associated narrowing of the range of mechanical properties for granules formed using an optimised procedure is exemplified by measurements of a number of parameters such as the coefficient of restitution. |
