The Instiute of Mechanised Construction and Rock Mininig - Warsaw, Poland - bought in China a concentracting table for dry cleaning of the type FGX-1. The unit has been tested mechanically since mid - November 2012. Preliminary research of coal dry cleaning has been conducted. These tests were designed to measure the impact of technical and technological parameters on the accuracy of the separation process of the coal from waste rock grains. This paper describes the principles of enrichment, the construction of air concentrating tables, and some of the parameters affecting the accuracy of separation of grains with different densities. It presents the results of dry coal cleaning experiments. The summary indicates the potential of air concentrating tables and highlights their strengths and weaknesses.
