TY - JOUR JO - Mining Science SN - 2300-9586 VL - 27 PY - 2020 ID - Baiul2020 TI - THE EXPERIMENTAL STUDY OF COMPACTION PARAMETERS AND ELASTIC AFTER-EFFECT OF FINE FRACTION RAW MATERIALS AB - Mining and metallurgical enterprises generate a significant amount of secondary raw material resources having small-fractions (below 3 mm). A significant volume of these materials can be returned into the production process by the use of the briquetting method. The quality of briquettes, in particular, their strength, is significantly affected by a phenomenon called elastic after-effect. For a theoretical study of the elastic after-effect influence on the quality of the briquettes, taking into account the pressing tool configuration, experimental data are obtained for three materials (peat, kaolin and manganese concentrate). Results are in creating the analytical relations (regression models) having enough high accuracy to describe the dependence of compaction coefficient, elastic after-effect, density and elastic heave (decompaction) on an external pressure in the compaction machine.
