ABSTRACT:
Process and apparatus for calcining finely divided cement raw materials including finely divided combustible materials in a suspension preheater with a calcining furnace. Finely divided calcareous materials are directly charged into the suspension preheater while finely divided argillaceous materials, including combustibles such as oil shale, are charged into a bypass duct for bypassing part of the high temperature gases in the suspension preheater to a calcining zone or calcining furnace. The raw materials charged into the bypass duct are subjected to thermal decomposition, resulting in solids and combustible gases. The combustible gases are separated from the solids and are charged into the calcining zone or calcining furnace while the separated solids are charged into the suspension preheater, mixed with the finely divided calcareous materials, preheated and calcined. Since the finely divided argillaceous materials are mixed with the finely divided calcareous materials, the smooth flow of the cement raw materials in the suspension preheater is ensured.
