Influence of Concentrating Table Deck Inclination Angles on Energy Reclamation Potential from Fine Coal Particles Based on Laboratory and Statistical Studies

Abstract

The article presents the results of research on enrichment of fine, raw coal grains using concentrating table. The reference point was a change of inclination of a table on actual value of separated products. Laboratory research that had been conducted, shown that with proper choice of technological parameter of a table, which was its inclination, produced coal concentrates having ash content of a few to a dozen percent, as well as waste with ash content of over an 80%. Second part of the article is the static analysis of conducted laboratory research, which has proved the correctness of the process performed and also a relation between technological parameters of concentrating table and obtained enrichment products.
