Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coalfired power plants. If a large amount of fly ash is not treated, it will produce dust and pollute the atmosphere. However, after processed, fly ash can be used as a resource, such as concrete admixture etc.

After grinding, the pulverized fly ash needs to be classified again in the powder concentrator. The fine ash that meets the requirements is sent to the fine ash silo through the conveying equipment, and the coarse ash is sent back to the ball mill for secondary grinding. The whole system is equipped with a dust collector.

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
