1500t/d
1.、Production scale, production method and cement types
1.1 Production method
一3.5×54m五
The production method is dry process. A rotary kiln(3.5×54m)
production line with five-stage cyclone pre-heater and
decomposition furnace will be adopted.
1.2Production scale and capacity
1500500000
The production capacity is 1500t/d for clinker, while 500,000t/a
for Portland cement when mixed with gypsum.
1.3 Cement types
GB175-1999,32.5MP、42.5MP
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.
