UNIVERSAL DEVICE FOR RESEARCHESBULK PRODUCTS FRICTION PROPERTIES

Abstract

Physical and mechanical propertiesof bulk materialsmust be taken into account when designingand operation of the agricultural equipment, devices for storage, and transportation of bulks materials. One of the most important physical and mechanical propertiesof bulks materials are coefficients of external and internal friction. In this regard, definition frictional characteristics of bulks material are relevant. The article shows the relationship between the properties of the bulk product and its coefficient of internal friction in the case of shear resistance. The main parameters of a universal installation for determining the frictional characteristics of bulk materials-static and dynamic, internal and external friction coefficientsare determined.
