GF-type impeller is the main equipment for powder storage pulverizing system of power plant boiler fuel supply, and use it to pulverized coal continuously and evenly into the primary air tube, blowing the boiler combustion. Relied adjustment to the amount of powder to control the boiler temperature and pressure, so as to ensure the required boiler output.
Impeller to contribute powder is determined according to a certain proportion of the volume. Thus, for milling system, building materials, metallurgy, chemical, civil and other departments, but also the wide selection based on technical performance, welcomed the order.
