First, the characteristics of fly ash The particles composition of fly ash. In accordance with the fly ash particle morphology, the fly ash particles are divided into: glass beads; sponge-like vitreous body (including the smaller particles and more dense, pore vitreous and particles, porous vitreous); carbon particles. Bead content of fly ash of power plant emissions in China is not high, most of the sponge-like vitreous, the particle size distribution is very uneven. Grinding processing, destruction of the morphology of the original fly ash, make it more uniform particle size broken polyhedron, increase its specific surface area, thereby increasing its surface activity, improve their performance differences.

Second, the fly ash application Fly ash can be used as cement, mortar, concrete admixtures, and become a component of cement, concrete, fly ash as a raw material instead of clay to produce cement clinker raw materials, manufacturing, sintered bricks, autoclaved aerated concrete, foam concrete, hollow brick, sintered and non sintered ceramsite paved road; build a dam, the construction of the port, farmland potholes lowlands, coal mining subsidence area and the mine backfill; from sorting floating beads, beads, fine iron powder, carbon, aluminum and other useful material, including floating beads, the beads can be used as insulation materials, refractories, plastics, rubber and filler.

Third, the prospect of fly ash [|rotary dryer] In coal-fired boilers system of power plants, fly ash emissions can be divided into dry discharge and wet discharge. At present, the developed areas in the cement industry, such as Jiangsu, Shandong, Zhejiang, Hebei, dry fly ash as an admixture in cement production, and the prices, has shown a trend in short supply, jumped to a resource; wet fly ash each item physical and chemical properties of dry fly ash, only because the big water (up to 45%), can not meet the requirements of the cement production, the attention of the market, can only be stacked in the wet gray library, a greater accumulation seriously pollute the environment. With the continuous optimization of the national industrial policy, environmental regulations become increasingly harsh, the proper handling of wet fly ash has been put on the agenda. Only the wet fly ash with reasonable energy consumption, simple process for drying so that moisture is low in order to change waste into treasure, and to achieve social and commercial benefits. The fly ash drying machine is widely used to solve the fly ash pollution and disposal problems, but also to make fly ash waste into treasure, an increase of economic benefits.
