Analysis of existing domestic production experience clay gravel indicates the possibility of changing the properties of the filler in a wide range due to dusting granular semi-finished product refractory powders introduced into the rotary kiln area directly in front of swelling. Found that the limestone flour, flue dust, and “tails” of the enrichment of iron ore conform to the dusting additives. The basis of selection is dusted additives on the assumption that increased fire resistance of the surface layers of granules dusting additive refractory powder, and made calculations of the melting curves of the clay-dusting additive. Investigations were carried out on the batch composition, mass. %: clay-95; flue dust-1,5; peat-3,5. Revealed the greatest effect of increasing the melting temperature on the surface of the pellets at the limestone by dusting with flour. Selected components dusting lead to lower density of 40-60 kg/m3 and a slight increase in sintering temperature.
