Minerals | Free Full-Text | Effects of Ball Size on the …

In this study, the ground talc powder using 0.1 mm balls shows a larger particle size than other talc powders with similar surface areas, which indicates that it is easily aggregated due to grinding. The increased aggregation of ground talc with 0.1 mm balls than with 1 mm or 2 mm balls could be related to the degree of dispersion in the aqueous solution used in the particle size analysis.
