Steel slag has a high application value after being made into powder. It can not only be used as pit filling and land reclamation materials, but also can be used as cushion and structural layers of road subgrades, especially as aggregates of asphalt mixtures to pave road surfaces. Therefore, the steel slag powder making vertical mill came into being, turning steel slag into treasure, effectively solving the problem of solid waste residue and protecting the environment.
What is steel slag? Steel slag is mainly composed of oxides of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus, etc. The main minerals are tricalcium silicate, dicalcium silicate, calcium-magnesium olivine, calcium-magnesium rhodoxene, calcium-aluminate ferrite, and solid solutions formed by oxides of silicon, magnesium, iron, manganese, and phosphorus. It also contains a small amount of free calcium oxide, metallic iron, fluoroapatite, etc., and the ore in some areas also contains titanium and vanadium.
Recommended use for steel slag production and processing: steel slag vertical mill, steel slag mill, steel slag ultrafine mill.
Process flow of steel slag milling
1. Large pieces of steel slag are transported to the raw material warehouse by a special vehicle, and then sent to the jaw crusher by a forklift or manually for crushing, and the crushed material is smaller than the feed size of the mill.
2.The steel slag crushed by the crusher is lifted to the storage hopper by the elevator, and the material is discharged from the storage hopper, and then fed to the main machine evenly by the feeder.
3. During the grinding process, the qualified products are screened by the screening system and enter the collector through the pipeline. After being collected, they are discharged through the powder outlet pipe as finished products, and the unqualified products fall into the main machine for re-grinding.
4. The purified air flows into the blower through the residual air pipe above the dust collector. The air path is circular. Except for the positive pressure from the blower to the grinding chamber, the air flow in the other pipelines flows under negative pressure, and the indoor sanitary conditions are good.
