CLASSIFICATION OF DISPERSE MEDIA BASED ON SECONDARY MATERIAL RESOURCES BY RHEOLOGICAL PROPERTIES

Abstract

The methods of granulation of multicomponent
polydisperse media (DM) are classifi ed depending on the
technological humidity, and special attention is given to the
description of rheological models of deformable bodies. The
possibility of such a classifi cation of DM is proved by the fact
that in the course of technological processing (mixing, granulation
by nodulizing and pressing) the material passes from
one rheological condition to another, often opposite to the fi rst
one. The general properties of DM packing and development
of their rheological properties under various conditions taking
into account mechanical and physico-chemical effects are
determined. The compression DM curves characterizing the
process of compaction from the applied pressure are given.
The mechanism of granulation is presented in the form of a
six-stage process refl ecting structurization of the material in
the course of its processing.
