In addition, the crushing degree of crushed stone aggregate was closely related to the change in the distribution coefficient r. The smaller the change, the lower the crushing degree. The crushing degree was the smallest when gradation 4 and the ratio of quartz to limestone was 3:1, and the change values were 0.038 and 0.073, respectively.

•The entire chamber is utilized for crushing. •The rocks falls/slides through the chamber until they are crushed directly between the concave and mantle. •The rocks are crushed in one strike which yields big forces •Most of the crushing in the lower part of the chamber. Feeding: Choke feeding yields more inter particular crushing
