Abstract
Coal excavated from a mine contains an average of 30% of polluting materials. To become a commercial product with the required quality parameters, this coal must be subjected to cleaning processes in a coal mechanical processing facility. In Poland hard coal processing and its recovery from mining waste is conducted on industrial scale, applying chiefly the gravity separation methods in a dense liquid or water medium. The coal processing in water medium raises many problems i.e. high energy consumption, necessity to apply dewatering processes, the maintenance of the water-sludge cycle, high processing costs. Thus, in the recent years, there is a growing demand for “dry” cleaning processes in air medium. Currently in the world, new constructions of this type of devices such as the FGX air concentrating table, sorter TOMRA, OSX can be found. Another type of machine used in air coal separation is a pneumatic sorter, constructed in the frames of the KIC project: “Novel dry sorter for coal processing and coal recovery from mine originating wastes” - AMSEP. A coal separation installation for coal processing as well as for recovery of coal from coal waste and the production of qualified coal fuels and mineral aggregates will be applied.
