subject: Development And Utilization Of Fly Ash Lead To Grinding Mill Favored [print this page] From coal combustion flue gas in the collection of fine gray down as fly ash, fly ash is a
major coal-fired power plant emissions of solid waste. After grinding with a grinding mill can be used as cement mixing
of fly ash, which greatly enhance concrete performance. With industrial development,
processing and utilization of fly ash has been greatly expanded the field, while large
vertical grinding milling machine is bound to become the preferred future fly ash processing
industry equipment.
Were suspended in the furnace of pulverized coal combustion conditions, non-combustible
materials in coal-fired (mainly ash) mixed with a large number of high-temperature flue gas
by high temperature and partial melting, surface tension and because of its role in the
formation of a large number of small spherical particles . Introduced in the boiler exhaust
fans under the action of the gas flow with a lot of ash furnace tail, part of the melting of
the fine by a certain degree of urgency due to the cooling showed vitreous state, which has
a high potential activity. Fan the smoke into the air before, these small spherical
particles, through dust, are separated, collected, namely fly ash.
Ash is the world's current emissions of large industrial waste, used grinding mill for processing is the most of
their potential use patterns. A lot of fly ash, if not addressed, will produce dust, air
pollution; if discharged into the river water can cause blockage of toxic chemicals which
will harm the human body and biological. Therefore, based on conserving resources, reducing
pollution, fly ash disposal and utilization has become the focus in a new domain.
Mechanical treatment by grinding milling of fly ash in China, developed a new type of wall
materials, concrete and mortar admixtures, development of marine concrete admixtures,
special admixture of Bridge and Tunnel, the new ladle insulation materials and other new
products also to fill the gap.
According to the current grinding mill technology development, large-scale ultra-fine
grinding milling machine has been able to achieve a one-time ultrafine materials processing
grinding mill processed by the fine fly ash material, uniform particle size, surface
activity, consequently, direct doped added to the concrete can save a lot of cement raw
materials; to improve the workability of concrete mixture; reinforced concrete plasticity
and stability. Even the cement manufacturers in accordance with 8% of the proportion of fly
ash mixed with cement clinker made of different varieties of finished cement. Fly ash has
been widely used in concrete admixtures, hollow brick, ceramics and construction backfill.
With the development of fly ash increasingly wide use of space, the corresponding grinding
mill on the technical standards have become more sophisticated, the traditional market,
Raymond grinding mill, ball grinding mill can not meet the industrial production of the
processing power and fineness of the needs of new vertical grinding milling machine, high
pressure suspension grinding mill and roller grinding mill ladder results and their latest
technology to facilitate efficient grinding mill performance will become the mainstream
