RESEARCH OF THE INFLUENCE OF THE SHAPE OF THE BUNKER ON THE CHARACTER OF THE FLOW OF POWDERED FLOOR MATERIALS

Abstract

Purpose. Study of the outflow of powder materials of different sizes from bunkers, establishing the nature of their movement and determining the relationships between the parameters of the bunker, its performance and physical and mechanical characteristics of bulk materials.

Method. The use of an experimental bench for the study of factors affecting the nature of the flow of bulk material and the numerical assessment of the relationship between the parameters of bulk materials and performance using Pearson correlation coefficients.

Research results. The characteristics affecting the characteristics of the flow of material of different sizes through bunkers of different shapes have been determined. Mathematical models of the movement of loose materials in bunkers of various shapes are presented, the influence of the dimensions of the bunker and the characteristics of particles on the speed of their movement is analyzed. Experimental studies of the flow rate of materials from bunkers were conducted, the results of which are presented in the work.

Scientific novelty. A mathematical model of the movement of loose material in bunkers of various shapes was obtained. The dependences between the physical and mechanical parameters of particles with different dispersion and their speed of movement have been established.

Practical significance. The development of technology involves a significant increase in the productivity of technological processes, a continuous increase in the quality of products produced. An important element of the development of modern production is the improvement of methods and their implementation in equipment to increase the efficiency of dosing of bulk products, which ensure the fastest and most accurate dosing. Research in such a direction as bulk material dosing is an integral part of the light, chemical and food industries. The obtained results will make it possible to predict the quality of dosing and the performance of bunker equipment for loose materials with different characteristics. In the future, it will allow to more expediently select the dimensions of the bunker equipment for dosing specific loose material.
