Industrial application of coal powder be separated from vertical roller mill.

The fly ash is the residue of the combustion of coal dust in the process of combustion, and his appearance is similar to that of cement, which is between milky white and gray black. The color of fly ash is an important quality index, containing carbon in fly ash from the depth of color can see his carbon content, but also can reflect the fineness of fly ash, generally the granularity of the deeper the color, the higher the carbon content.

Vertical rollers are commonly used in industrial applications in the United States to prepare pulverized coal, and the fineness of the product varies between 250-325 mesh, which can be used to adjust product fineness and yield during operation. Vertical roller mill has certain requirements for hardness. Compared with the traditional grinding machine, it enhances the stability and wear resistance of the work, and the grinding roller and grinding roller can be operated in a complementary state. While rotating, the mill can be used to enhance the efficiency and durability. Fly ash has low calcium fly ash and high calcium fly ash. The color of high calcium fly ash is yellow, the color of low calcium fly ash is gray. The fly ash granule is a multi-pore honeycomb tissue with a higher surface area and higher adsorption activity. The particle size range of the particles is 0.5--300 mu m. And the bead wall has the porous structure, the porosity is as high as 50% - 80%, has very strong water absorption. After absorbing the water, it will be sticky, which will affect the grinding of the grinder. Therefore, it is not necessary to add any grinding mill to prevent the fly ash from adhering to the cabin during the pulverized coal ash.
