Abstract

The paper gives a general characteristic of coal refuse processing products: intermediate fraction - coal-free screenings; small fraction - carboniferous sand containing up to 30% coal; fine fraction - silt coal containing up to 50% coal. Green and baked ceramic properties of products of processing waste coal are demonstrated. Compositions of raw mixes for items with compression strength of over 10-15 MPa with a density of below 800 kg/m3 are substantiated, with considerations for molding with semi-rigid extrusion and requirement of minimizing baking costs. Processing properties of screenings are presented as functions of material grinding and baking temperature. A process diagram has been plotted for a possible production facility using modern equipment. Technical and economic indexes are presented, showing high profitability and promising nature of manufacturing large-size structural clay tiles from the products of processing waste coal thanks to minimal prime cost of the tiles.
