Both sand and fly ash contain SiO2. The difference is different particles, fly ash fineness can up to produce brick standard, sand particle should combine with brick physical truth, If the grain fineness is not unqualified, the production line equipment need to add extra ball mill, for sand grinding.

In natural heavy placer elutriation separation process, light minerals such as feldspar, quartz etc most was separated, and heavy minerals such as magnetite, ilmenite, epidote accounted for more than half in the residual sand, because of the heavy mineral generally darker, make the sample it is gray, so called gray sand.

Fly ash, is fine ash , which is collected from coal combustion flue , fly ash is a major solid waste from coal-fired power plants. Main oxide composition of fly ash in thermal power plants in our country is: the SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 etc.
