Project Background

Slag is the waste discharged during mineral processing or smelting. The recycling of such waste in the new industrial age has yielded good results and occupies a very important position in aggregate production of cement or other fresh energy sources.

Raymond mill can process slag it?

Slag is the waste discharged during mineral processing or smelting. The recycling of such waste in the new industrial age has yielded good results and occupies a very important position in aggregate production of cement or other fresh energy sources. As we all know, you want to better use of slag to industrial production, it must be ground into powder, then the most familiar raymond mill can process slag? The following Xiaobian revealed to you the answer.

Raymond mill can process slag it?

The answer is: of course! Raymond mill can be processed to about 80-400 mesh slag, the slag can be processed into all the required fineness. First of all, the vibrating feeder delivers the material to the mill, the powder is collected by the blower to blow the powder into the powder collector and finally into the silo. The whole process is very convenient and dust-free. The new Raymond mill has been modified Set a high-pressure spring, so that more stable operation, production is also higher, is a cost-effective equipment.

Use of slag powder

After grinding the slag powder can be used to process slag concrete, slag Portland cement, slag cotton, wall materials, pressure pipes and other purposes, the following to you a detailed introduction.

Slag Portland cement: And clinker clinker powder in accordance with a certain percentage of the preparation of various grades of slag Portland cement, slag can increase the amount of incorporation, reduce the cost of cement production, improve economic efficiency;

Raymond mill

Slag concrete: can replace 10% -40% of the cement raw materials, to prepare concrete, saving the amount of cement, effectively reduce the alkali aggregate reaction, can improve the durability of concrete.

Slag powder cement characteristics

  • 1, reduce the amount of cement, reduce the cost of manufacturing cement;
  • 2, to improve the microstructure of concrete, so that the porosity of the cement slurry decreased significantly, strengthening the aggregate interface of the adhesive force, so that the physical and mechanical properties of concrete to a large extent improved;
  • 3, can improve the corrosion resistance of concrete, is very suitable for anti-sea water project use;
  • 4, resulting in more ettringite crystallization, can compensate for the excessive shrinkage caused by fine powder in concrete conditions;
  • 5, Effectively reduce the heat of hydration, is conducive to preventing cracks caused by the mass concrete interior temperature rise;
  • 6, to reduce the amount of concrete Qinshui, to improve the density and improve the workability and impermeability of cement;
  • 7, slag powder can greatly improve the strength of concrete, you can formulate high-strength concrete.

Slag powder grinding considerations

Slag has a certain degree of pollution and harm to the air, soil and water system. Therefore, when the production line is in a lot of mining and production of slag powder, dust removal work must be done. When mining minerals, the following methods can be used for antifouling: Fine tailing water, used to cover the lime and soil, cover the top with bark straw, planting windbreaks in the wind direction; 2, in the waste rock or tailings on the planted permanent plant; 3, The bound or bound material forms a consolidated crust on the tailings surface.

Slag powder in the production process also need to do a good job of dust prevention measures, the choice of dust-efficient dust collector is very important, Raymond mill is generally used bag filter, the use of circulating air pressure to ensure that equipment under negative pressure, The increased air flow can be discharged into the precipitator through the residual air and then purged to the atmosphere.
