Abstract
1368152 Rotary hearth furnaces SALEM CORP 13 Dec 1971 [20 May 1971] 57864/71 Heading F4B A rotary hearth furnace for burning limestone comprises a hearth 13 mounted on rollers, fixed roof 11 and side walls 12 supporting a preheating and feeding shaft 16, rabbles 19 mounted in the roof, burners 20 in the side walls and a known sand or water seal 22. Treated material leaves by an outlet 27 into a cooler 28 with air openings 30 through which air is drawn by a fan 36 arranged upstream of a pipe 31 and cyclone separator 33. The fan supplies the heated air to a manifold 35 from which branch pipes 37
