Abstract
In the semi-dry process for the manufacture of cement the starting material is pelletized with water and a bituminous binder. The bituminous binder may be a petroleum distillation residue, bituminous limestone or shale, tar or pitch. In the example, the water/bitumen binder was sprayed as an aqueous emulsion on to the starting material in a rotating drum granulator.
