发明名称 BURNING/ROASTING FINE-GRAINED MATERIAL
摘要 <p>A method of burning or roasting fine grain material comprising preheating the material in stages (1), largely calcining (5) the heated material, heating the largely calcined material to a temperature necessary for clinker reaction in the burning or roasting zone of a burner unit (8). At least part of the largely calcined material is supplied in suspension (28, to one side of the burning zone of the unit (8) and is guided through the burning zone in parallel flow with the combustible gases of the burner unit. After at least partial sintering, the material is conveyed back (30, 31) through the burner unit as a bed of material in counter current to the combustible gases for completion of sintering. A separating unit (7) for separating material and gas may be associated with the burner unit at the waste gas side. <IMAGE></p>
