= 205.0 µm). When grinding aids are applied during the milling of the heat-treated fly ash, the expected grinding aid effects can be observed. Interestingly, the addition of grinding aids leads to similar product finenesses as already achieved during the grinding of the raw fly ash.
Introduction. Fly ash is a pozzolanic materials containing aluminosilicate glass formed after the burning of pulverized coal [1]. It is rich in SiO 2, Al 2 O 3 in chemical composition, accounting for about 80% of the total mass. Moreover, mineral phase of fly ash is mainly composed of spherulitic glass phase which accounts for more than 50% of …

Highlights. Pre-grinding has a good promoting effect on coal gasification slag flotation. Compared with primary flotation, secondary flotation has better flotation performance and can obtain higher ash content of tailings. The tailings yield reach 37.67%, with an ash content of 91.77% and a loss on ignition of 8.23%.

Based on the results of mechanical activation of fly ash in stirred media mill, Molnár et al [21] reached submicron fine fly ash product at 7 m/s circumferential speed (stress intensity SI = 2.14×10-4 Nm) for 10 minutes grinding time (SSA = 7.76 m2/g, x 50 = 0.8 µm; x 80 = 1.98 µm).The amount of mullite 2:1
It can be find that the water and volatile content of raw ash is relatively fewer, only 0.75% and 2.37%; while the air-dried ash is 76.82%. The organic matter content of fly ash decreases dramatically after high-temperature gasification, while the inorganic mineral content increases and the ash content decreases.
