Based on the established correlations, some discussions on fine products distribution and the applicability of self-similarity are also presented. Our test results, particularly the distribution of fine fragments, demonstrate the suitability of self-similarity in the product size distributions after sufficient compression and breakage.

The family of size distribution curves has led some investigators to seek an equation, which describes that family. The product size distribution from the single particle breakage studies using the computer monitored twin pendulum device test by Narayanan [29] and Sahoo [31] exhibited a strong tendency to belong to a family of curves. This …

Abstract. A mathematical model analogous to the rate of decay of radioactive materials has been developed to describe the unit operation of comminution. The model provides a useful theoretical base from which the fraction by weight on screens of different sizes can be determined after defined periods of grinding.

Particle breakage in soils is a well-recognised behaviour. Conventional methods for quantifying the breakage process rely on calculating the area between the particle size distribution (PSD) curves produced before and after crushing. A key aspect of breakage is understanding the process across the different size/sieve fractions. Grading …
