PROCESSING OF BULK AND ROD MATERIALS IN COMBINED VESSELS

Abstract

Purpose and task is making research on the dynamics of a vibrating installation to process tubular materials and the kinematics of their movement (circulation) in hemispherical chambers.
 Methodology. To achieve the target goal, an expert assessment of existing approaches to methods of processing bulk and rod materials in air and liquid environments has been carried out.
 Research methods. Using vibrations for heat treatment of bulk and tubular materials makes it possible to intensify the heat exchange process, significantly reduce processing time, save fuel and electricity consumption, improve product quality, reduce costs on maintenance and environmental protection. The materials of theoretical studies on vibrating machine dynamics under different types of working body oscillations and the number of vibration drives are presented. Analytical dependences of vibration parameters have been obtained.
 The main results. Using vibrations to develop highly reliable and efficient technological units incorporating the performance of low technological operations in one device.
 Conclusions and practical significance. Based on the analysis of vibrating machines with a liquid environment, the results of research aimed at improving technologies and appropriate technical means to process bulk, lump and rod materials in air and liquid environments are provided. The solution of linear differential equations resulted in obtaining amplitude parameters of steady oscillations of an installation working body with relevance to the movement of working camera points and the installation angular oscillations as well. It has been proved that the amplitude of the vertical oscillations of the point is equal to the amplitude of the circular oscillations of the installation gravity center. Obtained rational trajectories of installation point oscillations to determine rational parameters are based on the requirements of material processing technology. The developed calculation methods can be used while studying machine dynamics of other types of a similar class containing liquid in the working space. Installation design makes it possible to adjust the oscillation amplitude and the nature of the trajectory of the installation working body points within wide limits.
