The material is fed into the crushing chamber between the machine body and the splitter ring by the screw feeder through the feed port, and is driven by the high-speed rotating hammer disk in the room, thrown to the stator gear ring fixed on the machine body, and is impacted and crushed. Under the pulling force of the negative pressure airflow, the crushed materials have small particles that overcome the weight of the powder particles and make them exceed the split ring and enter the classification chamber between the split ring and the grading impeller. The grading impeller is composed of blades, which are driven to rotate by a motor to generate an internal circulating air flow. When the powder passes through the gap between the grading impeller blades, it is subjected to three forces at the same time, namely the centrifugal force, gravity and the pulling force generated by the negative pressure airflow. Only the fine particles with negative pressure greater than the centrifugal force and gravity can pass the classification smoothly. The impeller enters the cyclone separator. Large powder particles are thrown to the shunt ring due to their large centrifugal force and return to the crushing chamber to be crushed again.

Technical characteristics of lithium iron phosphate jet mill

  • The grading adopts horizontal grading wheel, which has more accurate cutting accuracy and higher grading efficiency than vertical grading wheel.
  • The use of high-speed, small grading wheels to ensure grading accuracy, which is more than twice as accurate as the use of large wheels and low-speed jet mills.
  • After a special flow field design and high-precision mechanical processing, the energy consumption is reduced by 30% compared with the disc and cyclone jet mills under the same output.
  • Production serialization: 2～5000 kg/h; high fineness: d97=1～180μm;
  • Good particle shape, narrow particle size distribution range;
  • Program control, imported components; good man-machine interface, easy to operate;
  • Infinitely adjustable, stable operation, thorough cleaning, easy to change varieties;
  • Wide application range: various soft and hard materials with Mohs hardness below 9.5;
  • It has a wear-resistant protection device, and the life of the silicon carbide graded wheel is 1000H.
