What is the high fineness of coal for ultra-fine grinding?

There are many fields for ultrafine mill applications. China is a large coal-producing country. China's coal resources are also very rich. Under large reserves, coal production is also very large. Coal has been used as an important energy source in China. When processing coal, it can control the emission of exhaust gas, so it is favored by users.

After ultra-fine grinding of coal, fly ash is precipitated from the flue gas after burning coal. It is the main solid waste discharged from coal-fired power plants. If it is not treated in time, it will pollute the air. When it reaches the water, it will cause the river to be blocked. The ultra-fine grinding can effectively utilize the fly ash and can be used as the admixture of concrete.

When fly ash fly ash is mixed into concrete, it can not only replace cement and gravel aggregate, but also reduce the cost of concrete, effectively protect the environment, improve the workability of concrete, and improve the impermeability and sulfate resistance. And chemical corrosion resistance, which effectively improves the high temperature resistance of concrete and reduces particle separation and water precipitation.

Ultrafine grinding can be selected according to the specific requirements of fineness in the process of processing. The finer the fly ash, the greater its activity, from this point of view. The three-ring mill is a fly ash mill. Shanghai SBM combines the advantages and production experience of the mill for many years to produce ultra-fine grinding micro-grinding equipment with a fineness range of 325-2500 mesh.

Fly ash can be used not only in concrete, but also as industrial filler, papermaking raw material, agricultural fertilizer, soil improver, brick making, environmental protection materials, etc. The requirements for fineness of fly ash are different for different purposes, so fly ash grinding There are also differences in the choice of powder machine. For details, please call us. Shanghai SBM can be configured according to the customer's specific requirements to provide suitable fly ash grinding equipment.
