Abstract:
The method of improving the quality of coal by using a combined dry enrichment machine was
considered. The description of combined dry enrichment machine, intended to process the run-of-mine
coal from the Sarykol deposit of the Maikubensky lignite basin, was given. A coal concentrate,
middlings and other enrichment products which were received as a result of processing, are
accumulated in the warehouse. The main aim of the enrichment machine is to improve the qualitative
characteristics of brown coal and, first of all, is an increase of coal calorific value (heat of combustion)
and a reduction in ash content. As a result of enrichment, the shelf life of coal increases from 3 to 6
months.
