Cement kiln preheaters

Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln

    However, the amount of processing that can be achieved in the preheater is limited by the amount of exhaust gas leaving the kiln, the kiln flame being the only source of energy. The most common operational problems with these preheaters are imperfect entrainment of the meal, causing inefficiency, and blockages caused by sticky materials

    Sep 11, 2013 Coatings and blockages can often occur in the cyclone preheaters of rotary kiln plants for burning cement clinker. They result from the combined action of recirculating materials (alkalis, chlorides, sulfates), intermediate compounds from the decomposition of raw meal that have a tendency to stick together, and an extremely high dust loading in the atmosphere in the preheater
