The article presents the results of research of the process of petroleum coke grinding in the impact centrifugal mill. The aim of the work was to find optimal technological parameters for obtaining petroleum coke powders of a given granulometric composition. Experimental studies were carried out, including the analysis of the influence of the mass flow rate of the material, the rotor speed of the mill and the granule size of the initial material on the disperse composition of the product. The results have shown that the increase of rotor speed and reduction of initial granule size contribute to the increase of material grinding degree. Technological schemes of petroleum coke processing have been developed, which can be used in various industries.
