The recommendation for slag superfine powder preparation equipment

Posted: 2020 04 27 Source: Kefid Shanghai Machinery Views: 128

Studies have shown that with the increase in the amount of slag superfine powder, the amount of water used when the concrete reaches the same fluidity becomes less; and the elastic modulus and drying shrinkage of concrete using slag superfine powder are basically the same as that of concrete using pure cement. Freeze-thaw resistance, impermeability, acid resistance, sulfate resistance, heat resistance, and salt shielding are all superior to concrete using pure cement.

At present, the main equipment for slag grinding include ball mill, vibration mill, roller press and vertical mill. These devices can generally grind the slag to a specific surface area of 400~550m2/kg, which belongs to the high-fine grinding of slag.

Kefid's VM slag vertical mill integrates crushing, drying, grinding, grading, conveying in one. The system is simple and compact. It covers an area of about 50% of the ball mill and can be arranged in the open air, so it can greatly reduce investment costs. At the same time, the grinding roller directly crushes the ground material on the grinding disc, which has low energy consumption, and saves energy consumption by 30% to 40% compared with the ball mill.
