General comment The grinding of raw materials and calcinating for clinker are closely linked as one complete procedural phase in the new suspension preheater (NSP) kiln. In addition, the residual heat from the kiln in the calcinating process is used to dry or bake raw materials in the grinding phase with the addition of coal powder.The NSP kiln is a production system of high efficiency, good production continuity, high output, and low overall energy consumption. In addition, with better dust collection and noise elimination equipment, the production system of the NSP kiln can greatly reduce the consumption of resources and pollutant emissions. |
