Following particle size reduction and blending, the formulation may be granulated, which provides homogeneity of drug distribution in blend. This process also is very important and needs experience to attain proper quality of granule before tableting, quality of granule determines the smooth and trouble free process of tablets manufacturing.
The distribution of particles in a batch mill was observed to vary along the axis of the mill. The centre of the mill was overfilled with particles, U>1, while the regions near the mill ends were underfilled, U<1. The opposite was true for the grinding media. The data reported was based on measurements of particle distribution along the mill
Dec 29, 2018· Dec 29, 2018. What are Differential Particle Size Distribution and Cumulative Particle Size Distribution. Differential particle size distribution is the percentage of particles from the total that are within a specified size range; for example, 30% within 110um range, 50% within 1020um range, and 20% within 2030um range.
