Cinematics and volume deformations during roll-press briquetting

This work presents the research done on roll-press briquetting (RB) for loose materials. It investigates the mechanism of the capture condition formation for particles of loose material by the inclined walls of a cell for a rolling press. The mathematical models of the backing influence on the capture conditions and the compacting character for the compressed material have been constructed. The equations which describe the influence of the cell parameters on material compacting dependent on the roll turning angle and angular coordinate of the cell have been calculated. The dimensionless criteria which describe the RB and which allowed to recalculate the parameters of a modeling process for an industrial parameter and the compatibility estimation of the criteria have been calculated. For optimization of the technological parameters, the analysis of cell arrangement for the rolls of the briquette press has been given. The new models of laboratory and industrial briquette press have been designed and tested. The novelty of this construction has been proved by the Russian patents for a design of briquette press, working tool, and methods of the RB [The roll briquette press, Patent of Russia N2093364; The briquetting method of loose material, Patent of Russia N2100204; The roll for the briquette press, Patent of Russia N2116201].
