JET MILLING SYSTEMS

Finer particles.
New possibilities.

Use high-velocity gas and particle-on-particle collisions to develop fine powders without grinding balls. Build a route from small laboratory samples to pilot trials and production.

A PRACTICAL SELECTION HELPER

Find a practical starting point.

Compare laboratory scale, static or active classification, and drying/deagglomeration. Gas supply, collection and material trials determine the complete system.

Convert kg/h to g/h. These are published laboratory ranges; production rates require trials.

All options in this helper (6)
Laboratory Model 00 ↗

Compact laboratory micronizing with small-sample collection options.

Published throughput: 1–500 g/h; material dependent

Laboratory Model 02 ↗

Larger trials with replaceable liners and configurable collection.

Published throughput: 0.5–5 kg/h; material dependent

Jet-O-Mizer route ↗

Loop-style dry micronizing with static aerodynamic classification.

Confirm rate, gas and liner configuration by trial

Micro-Jet route ↗

Pancake-style dry micronizing with tangential nozzles and static classification.

Confirm rate, gas and liner configuration by trial

Roto-Jet route ↗

Opposed-jet fluid-bed grinding with an adjustable classifier wheel.

Wheel speed is an additional classification control

Thermajet route ↗

Flash drying with deagglomeration for suitable wet powders, slurries or filter cakes.

Drying route; not an interchangeable dry micronizer

START AT YOUR SCALE

Develop the process.
Then build the capacity.

Laboratory and production systems share the same objective: a useful particle-size distribution, practical recovery and a process that fits your material.

Lab Scale Jet Mills

SMALL SAMPLES & PROCESS DEVELOPMENT

Lab Scale Jet Mills

Develop the process with small quantities. Compare Model 00 and Model 02 systems, then configure feeding, collection and containment around your material.

  • Model 00 and Model 02
  • Optional sample collectors and HEPA filtration
  • Glove-box and controlled-atmosphere integration

SCALE-UP & CONTINUOUS PROCESSING

Pilot and Production Jet Mills

Scale fine-powder processing with static or active classification, application-specific liners and a complete feed-to-collection system.

  • Loop, pancake and opposed-jet designs
  • Static and active classification
  • Application-specific liners and integrated systems

Compressed-gas jet milling and static classification principle

HOW JET MILLING WORKS

Particle meets particle.
The powder changes.

  1. Introduce a controlled feed. Meter dry powder into the gas-driven grinding zone.
  2. Accelerate and collide. Expanding compressed air or inert gas drives particles into one another, reducing their size.
  3. Classify and recover. Fine particles leave with the gas stream; coarser material continues milling. Collection and filtration recover the powder.

There are no grinding balls to add or separate. Gas expansion can help manage process temperature, while liners and contact materials help manage wear and product compatibility.

WHAT A FINER POWDER CAN CHANGE

Start with the property.
Not just the particle size.

Surface area & response

Finer particles can change dissolution, reaction rate and interactions with other materials. Define the downstream performance you want to improve.

Distribution & consistency

The width and upper end of a particle-size distribution can matter as much as the average. Specify the measurement method and the target distribution.

Product integrity

Evaluate temperature, wear contribution, moisture, recovery and gas compatibility together. Finer powder is useful only when it still meets the product requirements.

STATIC VS ACTIVE CLASSIFICATION

What decides
which particles leave?

In both systems, process gas carries fine particles toward the outlet while coarse material receives more grinding. The difference is how that separation is controlled.

Static classification operating principle

Static classification

Gas flow and fixed geometry separate the particles. Aerodynamic drag carries finer material out while particle inertia keeps coarser material in circulation. There is no rotating classifier wheel.

Change feed rate, gas pressure and flow within the system’s operating limits. Choose this route for a simpler classification arrangement when trials demonstrate the required distribution.

Active classification operating principle

Active classification

A motor-driven classifier wheel creates an adjustable centrifugal barrier. Fines pass through the wheel; rejected oversize material returns to the grinding zone.

Wheel speed adds a control variable for the cut point and distribution. Increasing speed generally produces a finer cut under comparable conditions, with capacity and energy tradeoffs.

Active classification adds a moving component. Distribution width and cut size still depend on the material, gas conditions, feed and classifier configuration; validate them with a trial.

MATERIALS & APPLICATIONS

A wide range of powders.
A specific process for each.

Jet milling is a route to evaluate for suitable dry powders. Material hardness, elasticity, moisture and the required distribution determine whether it is the right fit.

  • Pharmaceutical powders
  • Battery materials
  • Pigments & coatings
  • Advanced ceramics
  • Industrial minerals
  • Specialty chemicals
  • Food ingredients
  • Engineering polymers
  • Metal powders

Suitability and achievable fineness require application review and representative testing. Some elastic, wet or cohesive feeds need conditioning or another processing route.

BUILD THE COMPLETE SYSTEM

The details shape
the result.

  • Liners selected for abrasion, purity and chemistry
  • Feeding and compressed-gas supply sized for the process
  • Product collection, filtration and controlled transfer
  • Sanitary access, cleaning and contained configurations
  • Controls and interlocks for the full installation

Review utility demand, sample recovery and operating cost alongside fineness and throughput. Inert gas and containment require an engineered system matched to the material.
