This article discusses the significance of the works of al-Beruni, one of the earliest scholars of the Middle Ages East, which is devoted to the study of the emergence of soil, its features and physical characteristics, changes in the structure of the Earth layers under various hydrographic conditions, and al-Beruni’s contribution to the development of the soil study in global scale.

The flow model of the crushing and crushing equipment is important because it allows the stone material to slide down through the crushing chamber. The crushing or crushing characteristics were achieved by testing the rock based on spring compression during crushing under controlled conditions. The input data (CSS) includes parameters such as speed, stroke, camera geometry, distribution of transmission values and mechanical properties of the material. The performance of a traditional cone crusher, which shows the performance for ore of various products. The nominal design of the conical crushing and crushing equipment is made. At this stage, it is possible to calculate a set of nominal parameters characterizing the chopper chamber. The nominal stroke and layer thickness are determined at each point of the chamber cross section. The same material was used in modeling and field tests. After each compression test, the material was screened. Distribution of the sizes received at each check. A selection function with two variables adapted to experimental data. b) functional representation in 3D. Normalized crushing of the porphyry material under study. b) the crushing properties of quartz and porphyrite were compared.
