Fluidized Bed Jet Mill
The fluidized bed jet mill is suitable for the fine and ultrafine size reduction of any material up to a Mohs hardness of 10 that can be fluidized by the expanded compressed gas in the grinding chamber.
They are typically used in applications where a fine to ultrafine micronization is required, and they are not limited by feed size, heat sensitivity of the material, or abrasive characteristics. They are characterized by decreased energy consumption, reduced wear and buildup in the grinding chamber, steeper particle size distribution, and low noise emission.
How it Works
- The feed material is introduced to the grinding chamber through a rotary valve or a screw feeder.
- Material is entrained by the high-velocity gas streams created by the nozzles, and size reduction occurs as a result of particle-to-particle collision in the gas stream and at the focal point of the nozzles.
- The coarse and fine particles are separated due to the centrifugal force generated by the rotating classifier.
- The fine particles that meet the size requirements enter the cyclone separator and dust collector for collection.
- The coarse particles descend to the grinding chamber for further size reduction.
