Fluidized Bed Opposed Air Jet Mill

Suitable for grinding materials with high hardness, high purity and high added value.

Fluidized Bed Opposed Air Jet Mill incorporates dense phase micronization using turbulent, free jets in combination with high efficiency centrifugal air classification within a common housing. This combination allows for enhanced comminution by high probability particle-on-particle impact for breakage and a high degree of particle dispersion for improved separation.

  • Low-temperature pulverization without medium, especially suitable for heat-sensitive, low-melting materials.
  • Control particle sizes precisely, available particle size D50:1~25μm.
  • Grinding in a complete closed system, no dust, low noise, clean and environmentally friendly.
  • Jet Milling is an effficient way to mill or micronize various chemicals, polymers, ceramics and other friable materials. Abrasive and temperature-sensitive products can be finely ground with minimum contamination. The simple, easy-to-clean, cost-effective design offers precise top size control with narrow size distributions in the 95% < 5 um to 95% < 70 um size range. Load cells are used to precisely control mill load for optimum grinding efficiency and/or product size distribution control.

According to different materials and application industries, the production capacity and particle size range will be different.

What is the working principle of Fluidized Bed Opposed Air Jet Mill?

Fluidized Bed Opposed Air Jet Mill: After the compressed air is filtered and dried, it is sprayed into the grinding chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The crushed materials rise with the suction of the fan. The airflow moves to the classification zone. Under the action of the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements enter the cyclone separator and dust collector through the classification wheel for collection, and the coarse particles descend to the crushing zone and continue to be crushed.

What materials work best for Fluidized Bed Opposed Air Jet Mill?

Fluidized Bed Opposed Air Jet Mill works great with most ceramics, glass, abrasives, minerals, and polymers, particularly those used in 3D printing applications. It is also an ideal process for toners, powder coatings, and other fine powder applications. If you’re unsure whether or not your particular feed will be a good fit, here are some material properties to consider.

Good candidates:

Dense materials
Hard materials
Round/spherical materials
Free-flowing materials
Materials that disperse well in air

Poor candidates:

Wet materials
Sticky materials
Entangled materials
Light/fluffy materials
Materials that do not disperse well in air

Predicting whether a material will respond to fluidized bed opposed air jet mill successfully can be difficult and often surprising, so it is always worth a feasibility trial to find out. Contact EPIC Powder Machinery today to schedule your material test batch.

Other Important Factors to Consider When Buying an Fluidized Bed Opposed Air Jet Mill

What is the particle size of your feed material?

Feed material greater than 1/4” cannot be directly handled by a fluid bed jet mill. An additional pre-milling option would first be required, such as hammer milling, roller crushing, or jaw crushing.

What is your target particle size?

EPIC Powder Mechinery’s Fluidized Bed Jet Mills are able to achieve particle sizes as fine as 1 micron with some materials. However, size distributions typically fall somewhere in the 5–70 μm range.

Is your material combustible?

If you plan to work with a combustible powder, you need to ensure that your Fluidized Bed Jet Mill has the necessary suppression systems in place. EPIC can customize any of our models to include explosion suppression systems.

Are your materials abrasive or heat sensitive?

Jet mills are efficient at grinding abrasive materials with minimal wear. This is because the system utilizes particle-to-particle impact driven by airflow, and is mainly composed of wear-resistant surfaces and components. And it can achieve zero metal pollution, controlling the temperature of the crushing chamber in the same time.
