Abstract
The study of the effectiveness of mixing process by screw conveyor using analytical methods is difficult and does not provide sufficient accuracy, so experimental studies with the design and manufacture of screw conveyor installations, in particular with rotating casings, are important. The purpose of the work is to conduct and present the results of experimental research on the bulk materials mixing quality using an automated installation of a screw conveyor with a rotating casing.
A prototype of an automated screw conveyor with adjustable material supply in the area of loading from the hopper and with provided rotary movement of the casing in the direction of rotation of the screw for simultaneous mixing and transportation of bulk materials was developed and manufactured. The experimental studies were conducted to determine the relationship between the structural and technological parameters of the screw conveyor-mixer, in particular the rotation frequency of the screw, the rotation frequency of the casing, the angle of inclination of the screw mixer, with the coefficient of inhomogeneity of mixing a combination of different bulk materials: grains of corn, millet, peas, wheat, buckwheat. Statistical processing of data from the results of experimental studies was carried out to obtain regression equations in coded and natural values of the dependence of the coefficient of inhomogeneity of mixing by a screw conveyor on its constructive and technological independent variable parameters, as well as checking the adequacy of the obtained equations using application software.
It was established that with a decrease in the rotation frequency of the screw and an increase in the rotation frequency of the casing and the angle of inclination of the screw mixer, the value of the coefficient of inhomogeneity of the mixing of three-component and two-component mixtures decreases. The maximum value of the coefficient of inhomogeneity of the three-component mixture of corn, buckwheat and millet grains was 11.28%, and the minimum value was 7.32%. The coefficient of inhomogeneity of mixing of a two-component mixture by a screw mixer with a rotating casing is 1.64 times smaller than the coefficient of inhomogeneity of mixing by a conventional screw conveyor with a spiral screw working body within the studied screw rotation frequencies from 250 rpm to 350 rpm.
