In industrial applications, mineral size reduction is very important. Grinding, also called fine milling or pulverizing, is the process of reducing materials to fine powder or very fine particle size. Fly ash may be used to replace a portion of the portland cement in concrete.
However, it first need to be collected, and grinded into fine particle, and then processed for making cement. In the production process, the fly ash powder mill involved including ball mil, coarse powder mill, high pressure mill, trapezium mill, vertical mill etc. SBM provides various types of fly ash powder mill for sale.
Fly Ash Recycling Application
Fly ash is a byproduct in coal processing and other production process, fly ash cannot be recycled in a closed loop and is thus different from most of the other materials considered in the warm emission factor analysis. Instead, it is recycled in an open loop, replacing cement in the production of concrete. Therefore, the benefits of using fly ash are equivalent to the emissions associated with the manufacture of the quantity of cement that is replaced by fly ash, minus emissions associated with transporting the ash to a concrete manufacturing facility.
