Preheater Cyclone in Cement Plant Thermal Efficiency

Lafarge on track for Ravena NY plant upgrade • Aggregate

Aug 29,  · The preheater uses kiln exhaust gases to preheat the incoming dry feed, increasing the thermal efficiency. The end product will be the same due to the limestone coming from the same quarry,” he added. Lafarge acquired the plant on its 3,000-acre site, originally constructed by the Atlantic Cement Company, in 2001. Source

Preheating before Calcination with High Efficiency and Energy Saving. Raw materials are sent into φ3.5×54m rotary kiln to be calcined after preheating and precalcining in the cyclone preheater. That is conducive to improve the production efficiency of kiln system, shorten rotary kiln length, and reduce the heat consumption of clinker calcining.
