Working principle

Large bulk materials through the jaw (hammer) crusher to the desired size, by the elevator to the hopper the material, and then by the electromagnetic vibrating feeder evenly host quantitative material continuously fed indoors grinding mill . After grinding the material is selected airflow blower powder machine grading, the role of classifier wheel, does not meet the requirements of the fineness of the material falling into the interior re-grinding mill, in line with the requirements of the fineness of the material with the flow through the pipeline inside into the cyclone powder collector, were separated and collected by the exhaust discharge device is finished powder. Airflow separated by cyclone powder collector tube into the upper end of the return air fan. The system is a closed loop system, and run under negative pressure condition.

Since the grinding mill interior being some of the water-containing material, the heat generated during the grinding mill chamber will cause evaporation gas expands changing air flow system, coupled with the feed port sealing problems at various pipe joining, outside ingress of air such that the air flow within the system out of balance, for which the fan through the outlet provided in the exhaust pipe valve the excess gas is introduced into the baghouse, and is discharged after purification, in the balance regulating system airflow while achieving environmental produce.
