Bojko Y. The research of grain products crushing process and the new ball grinder construction development

The dissertation is dedicated to the research of grain raw crushing. The new way of crushing and construction of grinder in which crushing occurs due to compress-shifting deformations by balls during reusable deforming have been proposed. It has been installed the influence grinder constructive-kinematical parameters on the ready product granulometric content. It has been substantiated the rational constructive-kinematical parameters as well as technique of ready product quality and productivity of grinder estimation. Efficiency of using of new way of crushing for grain raw with different structural-mechanical characteristics crushing has been proven. The industrial-experimental model has been made and researches in industrial conditions have been carried out. Keywords: ball grinder, constructive parameters, granulometric content, grain raw.
