ТЕОРИЯ И ПРАКТИКА БРИКЕТИРОВАНИЯ ПОЛИДИСПЕРСНЫХ МАТЕРИАЛОВ И ОТХОДОВ ПРОИЗВОДСТВА В ПРЕСС-ВАЛКОВЫХ АГРЕГАТАХ

Abstract

The article deals with theoretical and experimental studies of the compaction processes of various types of powdered polydisperse materials for the study of kinematic, design-technological and energy-power parameters of units. The basic laws of briquetting in press-roll units and the need for their constructive and technological implementation have been established. The calculation of the main energy-power parameters of the equipment for briquetting (pressing force; power expended by the roller and jaw pre-compactors; total power consumed by the roller press) is presented. It allows considering the physicomechanical characteristics and physicochemical properties of technogenic materials. The paper presents patent-protected designs of aggregates for briquetting polydisperse waste with both high and low bulk density. The necessity of preliminary compaction of briquetted charges during their molding is shown, which is effective in the implementation of any compaction process. The use of devices for preliminary compaction of the material and the forming elements of the grooved-toothed and cell-type rolls make it possible to obtain briquettes of a given geometric shape and dimensions, taking into account the requirements of the consumer. The results of theoretical and experimental studies can be used not only for the processing and disposal of secondary raw materials (polydisperse waste) of individual industries, but also for the production of various types of marketable products.
