| Abstract: | Stress—strain relationships of moist samples of dicalcium phosphate qualities with different particle size distributions are determined and compared with the granule growth pattern in a high-speed mixer. It is shown that granule growth by coalescence proceeds when a limiting agglomerate strength is achieved due to densification of the moist agglomerates. In the region of growth by coalescence, the growth rate is improved by an improved deformability of the moist agglomerates, while increasing strength delays the growth rate. The effects of agglomerate strength and plasticity are described mathematically by a model which outlines the main effects of the stress—strain relationship upon granule growth by coalescence. |
