Abstract
The results of experimental studies of grinding processes in a new centrifugal vertical grinder СVI designed at the IGDS, SB RAS are presented. The most important design factors for the equipment of the new type that affect the efficiency of geomaterial grinding taking into account the initial maximum size of the material are the gap between the working bodies and the location of the unloading unit for crushed geomaterial (relative to the central axis of the grinder body). The rational working parameters of the vertical centrifugal grinder were established by model tests with a laboratory sample (unloading angle –150 deg., the gap between the working disks - 3 mm). Changes in these factors within certain limits allow one to control the grinding process, in the combined mode of multiple dynamic and abrasive effects. The control of the grinding process consists in the possibility of limiting the output of under-crushed particles from the grinding zone, as well as setting the degree of reduction of disintegration products. The project and working documentation for a pilot industrial model of a vertical centrifugal grinder CVI-12 with a capacity of up to 12 t/h are developed.
