determining particle size distribution from a ball mill

A GUIDEBOOK TO PARTICLE SIZE ANALYSIS Horiba
measuring particle size before and after the process. Particle size growth may be monitored during operations such as granulation or crystallization. Determining the particle size of powders requiring mixing is common since materials with similar and narrower distributions are less prone to segregation.

MEDIA MILLING FOR CHEMICAL APPLICATIONS
disperser and a low speed sweep blade. (Fig. 2). The mill is designed for high circulation rate grinding. The entire contents of the holding tank are passed through the milling chamber at least once every minutes or about 8 times per hour. This high pumping rate results in a uniform dispersion, narrow particle size distribution and faster grinding.

optimum size ratio for a low viscosity dispersion is around, where we would use say, 175 nm latex in 750800 nm latex. The relationship between viscosity and particle size ratio at low shear is shown in Figure 5iii. It can also be shown that widening the particle size distribution further reduces the overall viscosity of the suspension.
