Abstract
The presented article discusses the use of gravitational enrichment methods for coal mining waste, namely screw separation. Since the equipment has a difference in its design, the authors of the article provide comparative data on the operation of two types of devices, the testing of which was carried out on the same raw materials.
Keywords
Coal sludge, Enrichment of coal sludge, Operating parameters, Granulometric analysis, Screw separation.
