Working principle

The bulk materials by jaw crusher to the desired size, by the elevator will be the materials to the storage hopper, then through the electromagnetic vibrating feeder will even materials quantitatively and continuously into the indoor host grinding grinding. After grinding the material was fan airflow into the powder selecting machine grading, the powder machine impeller role, does not meet the requirements of grinding fineness material into indoor re grinding fineness, comply with the requirements of material with gas flowing through the pipeline into the cyclone powder collector, were isolated and collected, the discharging device is discharged into refined powder. After the flow separation by cyclone powder collector upper return air duct into the fan. This system belongs to the closed circulation system, and the positive and negative pressure condition.
Because the grinding room were grinding material contains a certain amount of moisture, grinding heat generation causes gas evaporation grinding indoor expansion and change the gas flow system, and the inlet and the pipe joint sealing problem, enter the outside air makes the system within the gas loss to balance, therefore, by setting the the air outlet of the blower and the exhaust pipe valve excess gas into the bag filter, and the discharged after purification, the regulating system flow balance while achieving environmental production.
