The working principle of the grinding production line is that after the bulk materials are crushed to the required size by the jaw crusher, the hoister will send the materials to the silo, and then the vibrating feeder will send the materials to the grinding chamber of the main machine continuously and evenly for grinding. After grinding, the powder will be carried away by the air flow of the fan and graded by the analyzer. The powder with the fineness will enter the cyclone collector with the airflow for separation From the collection, and then discharged through the powder discharge tube is the finished powder.
The airflow is then sucked into the blower by the return air duct at the upper end of the cyclone collector. The whole air flow system of the mill is closed circulation and circulates under positive and negative pressure. There is a certain amount of water in the material to be ground in the mill room, and the heat generated during grinding causes the gas evaporation in the mill room, which changes the gas flow rate. At the same time, due to the loose sealing of the pipe joints of the whole machine, the external gas is inhaled, which increases the air volume of the circulating air flow. Therefore, the balance of the air flow is achieved by adjusting the residual air pipe between the fan and the host machine, and the excess gas is introduced into the bag filter The fine powder brought in by the residual gas is collected and discharged after purification.
