The Importance of Particle Sizing. At the simplest level, information on particle size can help maintain a more consistent product, enhancing end-user value and profitability. At a more complex level, careful control of particle size can reduce the need for in-process modifications and reworking, so making products more competitive

Sep 01, 2002 · Particle size reduction rate constants for particles as determined by the slope of first-order size loss plots under sonication are listed in Table 1. In control experiments to monitor the particle size change at different pH values (silica at pH 6, alumina at pH 2), no apparent difference in the rate of size reduction was found at different pH

Table 2 shows the results of the surface area analysis of the two biocarbons and talc, while Table 3 shows their particle size analysis. The results in both tables (Tables 2 and 3) show that using the ball-milling to reduce the size of the biocarbon particles was successful, the reduction depending on the time the particles spent in the ball-mill. As the surface area of BioCM/4HR increased, its average pore …

Jan 07, 2021 · Debris avalanches have complex structures due to the internal discreteness of fragmentation events. From a meso perspective, a debris avalanche is essentially a collection of debris particles of various sizes. Friction and collision events are directly influenced by the gradation of debris particles, restricting the movement process of debris avalanches
