On basis of many times experiments and improvement, introducing the latest mechanical techniques of Sweden, High Pressure Micropowder Grinding Mill, the latest industrial micro-powder grinding mill, is a new type grinding machine for producing micro-powder. there are some differences between high pressure grinding mill and raymond mill.

High Pressure Grinding Mill can grind calcite, limestone, calcite, dolomite, kaolin, bentonite, talc, illite, pyrophillite, barite, meerschaum, fluorite, potash ore and other more than 200 kinds of materials that Moh's hardness is below 6, non-explosive, non-flammable minerals.

It has been the main method for the large power plant dealing with fly ash that we use high pressure powder mill to process fly ash for recycling.

Coal fly ash, hunting down from the coal burning, is the main solid waste. With the development of the electric power industry, the coal fly ash emissions from coal-fired power plants is increasing year by year. At present, fly ash is one of the large industrial emission waste  in China. If  large amount of fly ash were not to be treated, it would generate dust and bring about atmospheric pollution; If the dust discharged into river, it would cause choke in river and one of the toxic chemical substances also be harm to human body and creatures.

Mixing the fly ash with concrete will save large amount of cement and fine aggregate; Reduce water consumption; Improve the concrete mixing content of workability; Enhance the concrete of the pumped; Reduced the creep of concrete; Reduce the hydration heat, heat expansion; Improving the concrete pervasion ability; To increase the modification of the concrete.

All the above features make powder mill become the main impetus for fly ash reprocessing. Being in line with the energy conservation, environmental protection and sustainable development principle, the solution using high pressure powder mill to deal with fly ash will cover power plant processing fly ash field in our country.
