ABSTRACT:
Disclosed is a method for reducing emissions from exhaust gas generated during the grinding and drying of cement raw meal as part of a cement manufacturing process. The invention comprises circuiting the exhaust gas between a raw mill and a clinker cooler. In the clinker cooler at least a portion of said emissions are delivered to a cement kiln in which said emissions are removed by being combusted and/or absorbed.
