gases and primary air are brought in a mill (4) that performs simultaneous grinding and drying of coal. After separation of ungrinded particles in inertial separator (5) aeromixture reaches aeromixture splitter (6). The splitter (6) divides the pulverized coal so that the level of its separations is g =,
27 blades are reasonable to obtain good separation performance. Abstract As a major equipment for thermal power plants, the main function of coarse powder separators is to separate particles into size groups according to particle diameter. With the rising coal prices, power plants are using more lowdensity lignite.
