EXPERIMENTAL AUTOMATED EQUIPMENT OF THE SCREW CONVEYOR WITH THE ROTATING CASING FOR BULK MATERIALS MIXING

Abstract

The article presents the design of the experimental equipment of the screw conveyor with the rotating casing developed on the basis of the received patents of Ukraine and manufactured for the study and selection of rational parameters of the simultaneous transportation and mixing of bulk materials. The experimental sample of the screw conveyor with the rotating casing provides the possibility of changing the conveyor inclination angle with the corresponding modifications of the hopper, the frequency and direction of the screw working body and the casing rotation, and also allows for quick change of the screw working bodies of various designs: conventional, with a variable diameter of the shaft in the loading area, with a variable pitch of flights, corrugated, with slots, with blades. The ability to control the screw conveyor and collect experimental data using the PC, Altivar 71 frequency converters, and PowerSuite software is provided. The use of an experimental equipment allows to study: the productivity of the screw conveyor when mixing bulk materials, the power of drives and torques on the electric motors shafts, the magnitude of the friction torque that occurs between the casing and the bulk material, the coefficient of inhomogeneity of the bulk materials mixing.
