A. Summary of cement plant equipment:
1. The production method is dry process. A rotary kiln(φ3.5×54m) production line with five-stage cyclone pre-heater and decomposition furnace will be adopted.
2. Production scale and capacity
The production capacity is 1500t/d for clinker, while 500,000t/a for Portland cement when mixed with gypsum.
3. Cement types
The technology and equipment adopted can produce 32.5MP and 42.5MP types of cement in accordance with Chinese Standard GB175-1999. They can be adjusted according to market demand.
