TRM series grinding mill is suitable to grinding Grade I fly ash, but difficult to improve the fineness of product. In order to fulfill superfine grinding of fly ash, we developed TRMF vertical roller mill (see figure below). The grinding table is in the shape of "concave" (material bed formed at inner side),
Fly ash particles larger than 10 μm were discharged into the "wheel roller mill" for grinding. The pulverized fly ash was then sieved by the "Ⅱ-grade cyclone sieving device" and the fine particles (< 5 μm) was discharged into the silo bunker. The advantage of this method is that fly ash with an average particle size of less than 5 ...
