Superfine grinding equipment (ultrafine mill) is mainly made up of main engine, reduction gears, analyzer, repairing platform, draught fan, powder collector, electrical cabinet, etc. The auxiliary engine is made up of jaw crusher, winnowing pan elevator, electro-vibrating feeder, material storage silo, etc.
The working principle is that large particle size material is crushed by jaw crusher to the necessary granularity, and then it is elevated by bucket elevator into material storage silo. Then vibrating feeder transports material uniformly and continuously into grinding room of main engine. The material powder after grinding is rising with blowing wind, and is classified by analyzer in which the matched fineness material is entered along with air pipe line into powder collector and is ejected as finished powder. The air is indrawing by upper return pipe of powder collector into centrifugal induced draft fan, whose air system process is closed cycling with negative pressure to ensure the clean and environment of working site.
