Working Principle
After crushing, the qualified material is fed evenly and quantitatively into the main grinding chamber by a variable frequency belt feeder for grinding. The ground material is then sent by airflow from a blower to a classifier for grading. Under the action of the classifier, material that does not meet the fineness requirements falls back into the grinding chamber for regrinding, while the qualified material is carried by the airflow through a pipeline into a cyclone dust collector for separation and collection. The collected material is then discharged as the finished powder through a discharge device. The separated airflow returns to the blower through the return air duct at the top of the cyclone dust collector. The system operates under negative pressure and is equipped with a pulse dust collector, meeting national environmental protection standards.
