Cement kilns-firing-hazardous-waste-pdf - SlideShare

The typical capacity of a new European kiln is 3,000 tons of clinker per day (Wulf-Schnabel and Lohse 1999). The Chinese cement industry produced 1, 038 million tons of cement in 2005 (808 kg per capita; 45.4% of world production)1. Approximately 60% was produced in 4,000 vertical shaft kilns (Karstensen 2006a).
