EFFECT OF SLUDGE OF SMELTING LEAD AND ZINC ON SINTERING CEMENT CLINKER IN WET PROCESS KILN

摘要

The effect of waste sludge of smelting lead and zinc on cement clinker sintering in wet process kiln are studied in this paper. The experimental results show that the waste sludge of smelting lead and zinc is successfully used for replacing 50% siliceous materials and 100% ferrous materials to sinter cement clinker in wet process kiln system, the fluidity and burnability of raw slurry are improved. Alite and the clinker quality are promoted.
