Airflow grinding can also reduce solid oxidants, explosives, and catalysts, and the combustion rate made of propellants can increase by 1 to 10 times higher than that of ordinary propellants, and improve the hit accuracy and power of the rocket engine. It is extremely important to realize the modernization of defense.
Airflow pulverizer can process ultrafine powder of various materials in dry, high purity, low temperature in its unique working principle, widely used in chemical, mining, abrasive, battery materials, refractory materials, non- Metal mine, metallurgy, building materials, pharmaceutical, food, pesticide, feed, new materials, environmental protection and other industries and ultra-fine pulverization, dissipation and particle shape of various dry powder materials.
The airflow pulverizer is one of the most important ultrafine pulverized equipment, with the advantages of low energy consumption, low wear, high grading accuracy, in the current The application is the most widely used in ultrafine pulverization equipment.
The working principle and characteristics of fluidized bed airflow pulverizer
Fluidized bed airflow pulverizer is combined with reverse injection or injection gas injection flow in the fluidized bed, and its working principle is:
(1) The material is given to the silo by the star valve. The screw feeder is sent to the pulverizing chamber or directly in the pulverizing chamber;
(2) compressed air, through the pulverizing nozzle, slowly expanding acceleration The jet stream forms a heart inverse jet flow field under the pulverizing chamber. Under the action of the differential pressure, the material is fluidized, and the accelerated material is integrated in the intersection of the multi-nozzle, producing a dramatic impact, collision, friction. Crushing;
(3) The pulverized material moves with the rising airflow to a certain height of the upper portion of the pulverizing chamber, under the action of gravity, falling into the mill under the mill, and the fine powder along with the airflow Movement to the top of the turbine classifier.
(4) In the flow field produced by the high speed turbine, the crude particles are pulled near the wall under the action of centrifugal force, and falls back to the lower portion of the grinding chamber with the stall coarse powder.
(5) Micro powder that meets the fineness requirements passes the graded flow path, conveying the exhaust pipe to the cyclone as a product collection, and a small amount of fine powder is further air solid separation by the bag trap, purifying the air Fan exterior.
(6) The connecting tube can be consistent with the pressure of the silo and the pulverization chamber.
(7) On the silo, the lower material is automatically controlled by the precision level sensor, and the pulverized ventricular position is automatically controlled by the dynamic current transmitter on the grading machine, and the pulverizer is always in Optimistic state.
The core R & D technology owned by the airflow pulverizer includes: the full use of jet energy, high-efficiency classification, severe controlling technology, reliable seal without leakage technology, large particle control technology, complete and smooth system design technology, crush Cavity constant gas solid concentration ratio technology, ultrafine powder collection dust removal and flue gas treatment technology, ultrafine pulverized particle morphology control technology, etc.
