Nevertheless, crushing granular materials is a complex process influenced by many factors. For example, the distribution of unbreakable particles in the volume of the sample is crucial. Steel balls need to touch good candidates for breaking (particles of similar size) to maintain the mechanism leading to fractal distribution.
During the crushing, the particle size of the material is reduced due to compression and shear forces as the material flows through the crushing plates. The crusher can be classified according to its capacity and the fragment size of the input material. Crushing was carried out in two stages; the second stage by choke feeding …
