Fluidized-bed jet mill specially for electronics materials

Principle:

       Fluidized bed airflow Grinder is a kind of equipment which uses high speed airflow to realize ultrafine crushing of dry materials. It is composed of crushing nozzle, graded rotor, helical feeder and so on. The material enters the crushing chamber through the spiral feeder, the pressurized air sprays to the crushing chamber at high speed through the specially configured supersonic nozzle, the material accelerates in the supersonic jet flow, and repeatedly hits and collides at the nozzle intersection to reach the crushing.
           The crushed material enters the grading chamber with the rising airflow, because the graded rotor rotates at high speed, the particle is not only subjected to the centrifugal force produced by the graded rotor, but also by the centripetal force caused by the viscous action of the airflow, when the particle is subjected The child is collected with the airflow into the cyclone separator and catcher, and the gas is discharged by the blower.

Product Features:

1,  Precision Ceramic Polyurethane lining, 100% to eliminate the material crushing process brought about by metal pollution. Ensure the purity of the crushed items. Particularly suitable for high iron content requirements of electronic materials, such as lithium cobalt acid, lithium manganese acid, lithium iron phosphate, lithium iron phosphate, ternary materials, cobalt trioxide, lithium carbonate, lithium nickel cobalt acid and other battery cathode materials.

2, It does not heat up, because the material is crushed in the gas expansion state, so the crushing cavity temperature control in the normal temperature state, the temperature will not rise.

3,  wear is small, because the main crushing effect is particle impact collision, high-speed particles and wall rarely collide, can be applied to crush Mohs hardness of more than nine levels of materials.

4,  Low energy consumption, compared with other types of airflow pulverizer energy-saving 30%〜40%.  for flammable, explosive materials can be used to protect and crush inert gas.

5,  The use of Advanced touch screen, programmable controller (PLC), to achieve automatic control.
