In the specific application, the superfine mineral admixture such as fly ash and S130 mineral powder with d97 being less than or equal to 10 mu m can be produced in a large scale.

Taking fly ash as an example, every ton of cement produced consumes 1.3 tons of limestone, 200 kilograms of coal and 80 degrees of electricity, and simultaneously discharges 0.8 tons of carbon dioxide and a large amount of harmful gases and particles such as sulfur dioxide and dust. According to the total annual cement yield in China, the dust amount and the waste gas amount discharged to the atmosphere due to cement production in China at present are respectively as follows: about 1330 million tons of various types of dust; in terms of exhaust emission, CO emitted to the atmosphere annually₂About 2 hundred million tons; SO (SO)₂The discharge amount is about 100 ten thousand tons; NO₂Discharge of 1.3X 10⁶～1.6×10⁶m²。

As the fly ash belongs to industrial waste materials and can be used as an admixture in concrete, but the fineness of the fly ash is difficult to break through d97 being less than or equal to 45 mu m all the time, the use ratio of a cementing material in the concrete is generally 25 percent, and the strength of the concrete before 28 days is reduced once the proportion of the fly ash is increased.

In the specific application, the process disclosed in the embodiment can be used for producing the ultrafine fly ash with the d97 being less than or equal to 10 microns in a large scale, the proportion of the fly ash with the fineness replacing cement can be increased by a large proportion to reach 50%, the concrete strength can be ensured and even improved, the enterprise cost can be reduced, and the crack resistance, the fluidity and the durability of the concrete can be improved. If the national utilization of industrial waste materials of fly ash is doubled, only one item in the cement industry can reduce the emission of general cement waste gas by 1 hundred million tons.
