Distribution of original surface features during comminution

Abstract

When a brittle solid particle is comminuted, its surface features such as the original surface area, edge length and corners are distributed among the daughter fragments. From a set of simple assumptions, a model was made of the distribution of these particle surface features. The mass vs. size distribution is very steep for fragments that contain original surface features. However, the cumulative distribution of the original corners, edge length, and surface area, versus fragments size all have a slope of m, similar to the size distribution curve of comminuted material. In addition, it has been shown that the total surface area of those fragments that contain some of the original surface area is constant, regardless of how finely these fragments may be ground.
