Abstract. Reduce the cost of crushing the rock mass requires the development of new methods and technologies to improve the efficiency of the grinding process. To this end, created the design of vertical vibrating intra-roller mill using shear forces during grinding, also made its modernization, which consists in a vertical arrangement of the rollers, changing the height and pitch helical winding, which increases in the direction of material feed. To confirm the performance of the proposed design and the definition of its technological characteristics of experimental studies to establish the dependence of the performance of the mill from its main parameters affecting the grinding process: frequency of rotation of the vibration, the backlash of the discharge opening, the height of the helical winding. Subsequently, to identify the impact of these factors on the performance of the mill, the identification of the experimental data was carried out and the calculated generalized mathematical model of the mill. These results allow us to determine the dependence of the performance of the mill variables, mathematical model makes it possible to choose rational parameters of the mill and proves the effectiveness of the modernization will increase the intra-roller mill productivity by 1.8 times.

Keywords: mill, modernization, productivity, winding, backlash, vibration, mathematical model.
