As a beneficiation or smelting slag after the achievement of a residue, slag vertical mill grind through different fineness slag powder, humans are increasing the intensity of the resource utilization of industrial solid waste, to minimize hazards brought by industrial solid waste at the highest degree.
Slag powder equivalent amount to replace cement of concrete and cement products, can significantly improve the overall performance of concrete and cement products. Slag powder as a new high-performance concrete admixture has the advantage as following:
1. Slag powder can greatly improve the strength of concrete; can be formulated surplus of high-strength concrete;
2. Can effectively inhibit alkali-aggregate reaction of concrete, significantly improve the performance of alkali aggregate reaction of concrete and improve the durability of cement concrete;
3. Slag powder concrete can effectively improve the performance of anti-sea erosion, especially for anti-sea engineering;
4. The amount of water bleeding of cement can be significantly reduced and to improve the workability of the concrete;
5. Slag powder can significantly increase the density of concrete and improve the impermeability of concrete;
6. Slag powder can significantly reduce the heat of hydration of cement concrete, suitable for mass concrete configuration.

| Equipment selection program | Vertical grinding mill |
HLM vertical grinding mill can be widely used in electricity, metallurgy, cement, chemicals, non-metallic mineral industries, mainly used for grinding and processing of cement raw material, clinker, power plant desulfurization limestone powder, slag powder, manganese ore, gypsum, coal, barite , calcite, bauxite and other materials.
Phrase one: raw material crushing
Slag blocks will be crushed to 15mm-50mm fineness by crusher.
Phrase two: grinding
Crushed slag material will be sent to the storage hopper by the elevator, and then the feeder will send the material to the main mill for grinding.
Phrase three: classifying
Ground slag powder will be classified; coarse powder will fall back to the main mill to be ground again.
Phase four: production collecting
qualified powder will flow with the air and be collected in the dust catcher, then the finished powder will be transported to the product storage bin through discharge port. Lastly, the powder will be loaded by tank car or packed by packing machine.
