Milling Process of Air Jet Mill
Raw Material Inlet
ㆍThe hopper supplies the raw materials to the Jet Mill in precise amounts through a screw feeder.
Milling
ㆍParticle-to-particle collisions minimize contamination.
ㆍUniform particle distribution ensures optimal ultra-fine milling.
Collection
Cyclone
ㆍFor precise fine powder control,
particles are collected in a cyclone.
Bag Filter
ㆍCompressed air pulses from the top of the bag filter release adhered powder,
discharging it downward.
Sieving & De-ironing
ㆍUltrasonic vibration ensures even particle flow into the de-ironing unit.
ㆍMagnetic impurities are removed by strong electromagnets in the de-ironing unit.
Packaging
1. Raw Material Inlet
Raw materials are loaded into the hopper and fed into the Jet Mill via a screw feeder.
Flap valves are alternately opened to maintain chamber pressure and ensure precise supply.
2. Milling Process
Milling
Compressed air is injected through nozzles to create the milling zone.
Materials collide within the milling zone and are broken down.
Classification
Particles milled in the classification zone are carried upward by the airflow toward the classifier wheel.
Particles at the target size pass through the classifier wheel, while oversized particles are rejected, fall back into the milling zone, and undergo re-milling.
3. Collection Process
Cyclone
Inside the cyclone, the airflow rotates like a vortex.
Following the airflow, target-sized particles are discharged downward,
while finer particles move upward and are carried into the bag filter.
Bag Filter
Particles of the target size that pass through the classifier wheel adhere to the surface of the bag filter along the airflow.
Compressed air is momentarily pulsed from the top air pulser of the bag filter,
releasing the particles attached to the filter surface and discharging them downward.
4. Sieving & De-ironing Process
Ultrasonic Sieve
Powder (product) collected from the bag filter is fed into the ultrasonic classifier.
The powder passes through the sieve mesh by ultrasonic vibration,
ensuring consistent and uniform feeding so that the downstream magnetic separator can effectively remove iron content.
Magnetic Separator
The powder evenly fed through the sieve is exposed to the strong electromagnets of the separator,
where magnetic impurities are removed and the cleaned product is discharged downward.
5. Packaging Process
Final Product Packaging
The product that has passed through the magnetic separator is packaged in a way that prevents dust and material loss, using a chucking master system.
