Abstract
The article offers analysis of the grinding process of friable material at the hammer crusher. The
process takes place at the working chamber of crusher using moving hammers. The article presents
the definition of physical and mechanical properties of the mixture. The properties influence on the
extent of grinding. Also the article presents the definition of the correlations between extent of
grinding and sizes of particles. The factor of solidity specifies in the formula calculation of
performance. The authors have considered this factor on condition of the continuous flow of the
mixture at the working chamber of crusher with predetermined speed and performance.
