Beater wheel mills in lignite power stations usually have a flue gas recirculation duct which allows the use of hot flue gas to dry the lignite during the grinding process. The beater wheel itself is grinding element as well as mill fan at the same time. The speed of the wheel determines not only the crushing process of the lignite but also ...
The mill has a deflector plate (12) fitted on the two opposite walls of the coal dust pipe (10) in its vertical section between the discharge of the separator (4) and the branch of the dust burner pipes (11), and protrudes into the edge region of the dust pipe. The walls accommodating the deflector plates lie in a plane in which the dust pipe branches.

The mill and the air classifier (Fig. 1.) operate in a closed-circuit grinding system (Beater Wheel Mill). The product of the mill–classifier cycle is transported by the flue gas, through a heat isolated pipe into the burner in the furnace. One furnace is supplied by four fuel preparing systems, each with a beater wheel mill and a burner.
Beater wheel mills are designed to prepare a coal powder air fuel mixture for combustion in furnace chambers of coal-fired power plants by coal drying, pulverizing, classifying and transport. Their multipurpose function usually results in operation instability accompanied by unacceptable vibration. This usually is a significant problem due to unplanned …
