The hot and cold exhaust gases from the main conveyor, subsidiary conveyor, sifter etc are drawn in by the suction side of a cyclose precipitator in which the coarse fraction is extracted and then fed back into the main conveyor before again passing to the sifter. The cold exhaust gas with its fine dust content is passed from the cyclone through a blower back into the tube mill as fresh gas supply. |
