Due to factors such as early input of roller presses, small selection, the cement semi-final grinding system has problems such as high power consumption and low output. By combining the existing two small roller presses with one ball mill to form a "two drag one" double closed circuit semi- final grinding system, and adding a large roller press system, the energy efficiency utilization rate of the roller press has been improved, the operating pressure deviation has been improved, and the crushing capacity has been enhanced. At the same time, by changing the internal structure of the ball mill from two chambers to three chambers, using ceramic ball grinding bodies in the third chamber, replacing anti blocking ball mill partition plates and discharge grate plates, optimizing activation rings, etc., the cement particle grading has been optimized. The comprehensive power consumption of cement grinding has been stabilized at around 22kW·h/t, and the system output has been increased from 190t/h to 325~335t/h, providing an important technical approach for energy conservation and carbon reduction in cement production.
