segment: Our DGS® mill (Distributor Blower Beater Mill) has proven itself, for example, in the drying and grinding of lignite with difficult grindability properties. Our NV mill (wet coal fan mill) is preferably used for lignite with a high water content. Both mill types can be equipped with a classifier or vapour separator if required.
For this reason lignite milling and drying is performed with fan beater mills, which use hot flue gas extracted at the furnace exit level. MHPSE has developed two types of state of the art fan beater mills, the DGS mills (Fig. 5.7) and the NV mills (Fig. 5.8). Download : Download full-size image; Figure 5.7.
