|With industrial development, field processing and utilization of fly ash was greatly expanded, and large [url=http://www.quarrycrusher.cn/product/vertical-roller-mill-operation.html]Vertical Roller Mill Operation[/url] is bound to become the first choice for the future of fly ash processing industry. Flue gas after combustion of coal collected down fine ash called fly ash, coal-fired power plant fly ash is discharged from the main solid waste. China is also the country's coal production and coal consumption, thus mill, coal, flour mill began to dominate the market, after the mill with fly ash can be used as cement after finishing materials, greatly enhance the performance of concrete . According to the current technological developments mill, ultrafine mill large been able to achieve on-time ultrafine materials processing, ash fines processed by the mill, uniform particle size, surface activity increased, direct doping increase in concrete can save a lot of cement raw materials, to improve the workability of concrete mixture, enhanced plasticity and stability of concrete. Even about the cement manufacturers have been 8% according to the proportion of the different species of fly ash cement clinker incorporation into finished cement. Ash has been widely used in concrete admixtures, hollow brick, ceramics and construction backfill.|
With the development and utilization of fly ash increasingly broad space, the corresponding mill technical level requirements are also increasing, the market of traditional Raymond mill, ball mill has been unable to meet the industrial production of processing capacity and fineness needs, the new vertical mill, high pressure hanging roller mill and high-pressure micro powder mill with its latest technological achievements and facilitate efficient use of performance will become the mainstream equipment milling machines.
