is fly ash after combustion of pulverized coal in boiler of power plant discharge of industrial wastes, our country is a country of coal, thermal power plant in China accounted for a large proportion of surprising number of fly ash generated by the thermal power plants each year. So, how to use fly ash, recreating a certain economic interests is an important research topic. With the improvement of technology, technological innovation has been successfully applied in the areas of comprehensive utilization of fly ash, recycling of fly ash at present there are the following ways: fly ash cement and fly ash bricks and silicate blocks, aerated fly ash concrete containing fly ash, soil conditioner and fly ash ceramsite with fly ash, etc.
fly ash reuse area so widely in order to resource recycling large amounts of fly ash, dedicated to the utilization of fly ash and special equipment development, on the existing basis of Raymond mill, concentrated research and development, technological improvements, and developed a number of new mill, raise the level of a fly ash utilization technologies and equipment. New fly ash mill is to solve the environmental problems caused by fly-ash, coal ash pollution reduction, covers a wide range of effective ways. New fly ash mill are: vertical milling machine, Super pressure trapezium grinding mill, trapezium mill.
in the following vertical milling machine, the EU version of the mill and Super pressure trapezium mill after the launched application, has introduced a new mill-style coarse powder mill, mainly applied to some areas of coarse powder processing, solves the problem of fine mill products too low in the past. Coarse powder mill is mainly used in areas not requiring processing, does not require fine grinding, nor requires particle separation, use coarse grinding can be met efficiently, meet the basic production needs of customers, and low investment, low cost, for our customers, with great development value, selection became rough grinding device of choice.
