1. What are the characteristics of fly ash mill?
Fly ash from coal combustion flue gas after the closing down of a fine catch ash, coal-fired power
plant fly ash is discharged from the main solid waste. China's thermal power plant fly ash is
mainly oxide composition of: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 and so on. Fly ash is one of
the larger displacement of current industrial waste, with the development of the electric power
industry, fly ash emissions from coal-fired power plants every year. Lot of fly ash not addressed, it
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 can also cause harm to humans and creatures.
Also available as an admixture of fly ash concrete.
Micro aggregate effect of fly ash: fly ash particle size small beads and debris can be equivalent in
cement unhydrated cement particles, very tiny beads equivalent lively nanomaterials, can
significantly improve and enhance the structural strength of concrete and products to improve the
homogeneity and compactness.
Re-election in mineral production sharing terms can be summarized as follows;
(1) ore pre-selection, in coarse or medium, under fine conditions, pre-selected part of the final
tailings, mine was selected to reduce the amount of primary election, reduce production costs;
(2) ore primary election will be useful minerals and gangue or separated from the surrounding
rock, to get the final concentrate and final tailings (or in mine)
(3) to form a coalition with other beneficiation processes, a comprehensive recovery of useful
components or coarse, fine particles were treated;
(4) dressing, add the recovery process after the main associated elements.
