Fly ash is fine ash collected from the flue gas after coal combustion, and is the main solid waste discharged from coal-fired power plants. The main oxide composition of coal ash from thermal power plants in my country is: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc. According to the morphology of fly ash particles, it can be divided into glass beads, spongy glass, carbon particles and so on. Most of the fly ash discharged from power plants in our country is a sponge-like glass body with extremely uneven particle distribution, which usually requires grinding treatment to improve its performance in order to be put into use. Fly ash is one of the largest industrial solid wastes in my country, with an annual output of about 500 million tons, which causes great harm to the environment and human health.

Fly ash processing and production process

Front stage

Raw material storage The fly ash in the flue gas of the power plant is collected by an electric precipitator or pulse precipitator, and transported to a powder tank for storage.

second stage

Grinding The fly ash in the powder tank enters the MTM trapezoidal mill or MTW European mill through the feeding device for pulverization, and grinds to 325 mesh, with a sieving rate of 88%.

The third phase

The collected fly ash is collected by the powder collector and dust collector.

The fourth stage

Finished product transportation The collected finished product is sent to the downstream or finished product warehouse.

Required equipment

As an industrial powder, the processing cost of fly ash directly determines the profit of investors. Therefore, under the premise of a certain investment, rationalize the production line configuration plan, and make the entire production line reach a very large output as much as possible, which will greatly improve the final economic benefits. Nowadays, the more successful production lines are generally composed of feeders, MTW series European T-shaped mills, etc.
