vertical mill machine-the first choice to processing fly ash

Collected down from the flue gas after combustion of fine coal ash called fly ash, fly ash is the main solid waste discharged from coal-fired power plant. After grinding mill with fly ash as a cement mixer can greatly enhance the performance of concrete. With industrial development, processing and utilization of fly ash field was greatly expanded, and large vertical mill machine is bound to become the first choice for the future of fly ash processing industry.

Vertical mill machine is the Great Wall Machinery to solve the low output, energy consumption and higher technical problems in industrial mill , absorbing the European advanced technology combined with our company for many years design and manufacture of advanced mill concept and market demand, after years of painstaking design of improved large-scale grinding equipment. Vertical mill uses a reasonable and reliable structural design, with advanced technological process, set drying, grinding, separator, upgrade in one, especially in the large grinding process, fully meet customer demand, the main technical, economic indicators have reached the international advanced Level.

Pulverized coal is suspension in the furnace combustion, coal in the incombustible material (mainly ash) mixed by a large number of high temperature and partial melting in high temperature flue gas, and due to its surface tension, forming a large number of small spherical particles . Cited exhaust fan's role in the rear of the boiler, the flue gas flow containing a large amount of ash furnace tail portion of the molten fine particles due to a certain degree of urgency cooling presenting vitreous state, which has a higher potential activity. Before the induced draft fan flue gas into the atmosphere, these small spherical particles, through dust is separated, and collect the ash.

Fly ash is one of the larger displacement of current industrial waste, the use of vertical mill process is currently the most promising way . In this stage of the amount of slag has reached 30 million tons, with the development of power industry, fly ash emissions from coal-fired power plants will increase year by year. Lot of fly ash, if not addressed, will generate dust, pollution of the atmosphere; if discharged into the river system can cause blockage of the river, and one of the toxic chemicals will cause harm to humans and creatures. Therefore, based on resource conservation, pollution reduction, treatment and utilization of fly ash has become a new area of much concern.

According to the current mill technology development, large-scale ultra-fine mill machine has been able to achieve a one-time ultrafine materials processing, fly ash fines by the mill processed, uniform particle size, surface activity increased, directly mixed add in concrete can save a lot of cement raw materials; improve the workability of concrete mixture; enhanced plasticity and stability of the concrete. Even the cement manufacturers have been 8% according to the proportion of the different varieties of fly ash incorporated into finished cement clinker cement. Ash has been widely used in concrete admixtures, hollow brick, ceramics and construction backfill.

With the development and utilization of fly ash increasingly wide space, the corresponding level mill technical requirements are also increasing, the market of traditional mill, ball mill can not meet the industrial production of processing power and fineness needs, a new type of vertical mill machine for its latest technological achievements and facilitate the efficient use of performance will become the mainstream equipment mill machines.
