In recent years, with the implementation of policies such as capacity replacement, peak shifting production, production reduction and energy discharge in the cement industry, the phenomenon of cement overcapacity has been gradually controlled, and the utilization rate of cement capacity has been continuously improved.
Slag has become an important admixture of cement, but the grindability of slag is very poor, so it is particularly important to choose an appropriate process. The processes of CO grinding, separate grinding, mixed grinding and combined grinding based on roller press are analyzed and compared respectively. It is considered that the use of roller press for pre grinding of slag can improve the quality of cement and save energy. At the same time, the selection of grading equipment in the pre grinding system is also very important.
