Recently, a 4500t/d clinker production line of a cement enterprise in Northwest China has supplemented 2500t/d production capacity, and the actual overcapacity is at least 55.56%. Similar situations have been seen in many places recently. In the central, northeast, central and southern regions, the proportion of clinker production lines is between 50% and 60%, and the proportion of clinker production lines is between 30% and 50%.
Serious overproduction is an important reason for overcapacity. The actual production capacity of some production lines far exceeded the design value, the reduction effect was weakened after capacity replacement, and a large number of "zombie production capacity" was revived.
