Rock Fragmentation Size Distribution Prediction and
网页2021年1月22日 Rock fragmentation size distribution is often used as an important index to account for the blasting effect because it directly affects the subsequent loading, transportation, and secondary crushing. Due to the mismatching of explosive and rock wave impedance, high boulder yield often occurs which affects the blasting effect.

Empirical energy and size distribution model for predicting
网页2021年9月1日 The analysis of the size distributions shows that there is a linear relationship between the size distribution and the breakage energy. In work, by Lindqvist (2008), an attempt was made to expand the Bond Work Index model to estimate the breakage energy needed to achieve a given product size distribution. This work indicated that the width of
