Characteristics and preparation equipment of slag superfine powder

　　The results show that with the increase of slag superfine powder, the amount of water is less when the concrete reaches the same fluidity. Moreover, concrete with slag superfine powder has basically the same elastic modulus, dry shrinkage and concrete with pure cement, and is superior to concrete with pure cement in terms of freeze-thaw resistance, impermeability, acid resistance, sulfate resistance, heat resistance and salt shielding.

　　At present, the main equipment of slag grinding includes ball mill, vibration mill, roller mill and vertical mill. These equipment can generally grind slag powder to specific surface area of 400~550m2/kg, belonging to high fine grinding of slag.

　　Kefid's LM slag vertical mill integrates crushing, drying, grinding, grading and conveying. The system is simple, compact and covers about 50% of the total area of the ball mill system. At the same time, the grinding roller grinds and grinds the materials directly on the grinding plate, which has low energy consumption and can save 30% ~ 40% compared with the ball grinding system.
