The whirlwind air classifier of LHB-C series for coarse powder is innovatively designed. It is composed of classifier, housing, air dispersing cone, air circulating unit, and fineness control device. The raw material is delivered to the air separator and then raised by airflow. The coarse powder will drop down to the conical part and discharged. In the meantime, the fine powder is separated by the fan impeller.
The whirlwind air classifier is extensively used for processing limestone, gypsum, bentonite, quartz, cement, coal powder, clay, fly ash, kaolin, feldspar, slag, barite, and other abrasive materials.
