Micronizing and Drying Powders since 1955, Experts in Equipment Engineering and High Quality Contract Powder Processing.

Tolling Services


Jet Milling

Fluid Energy’s founder was an early develop of the jet mill and we have been a leader in providing Jet Milling Services since the early 50’s. Our jet mills micro-pulverize powders by using a high pressure compressed air and cyclonic air movement to produce a very specific range of particle sizes.

The resulting narrow size distribution is one of the main benefits to using jet milling as your grinding solution. Jet Milling can accommodate a variety of raw feed stock sizes and reduce the material to sub-micron to 100 microns in size.

Fluid Energy offers 3 main types of Jet Mill including our patented Jet-O-Mizer, Micro-Jet and Roto-Jet. These 3 models give us the flexibility to match the throughput and desired particle size to out customers exact needs and offer solutions to a wide range of industries.

Our Jet Mills are designed to operate with inert gases and steam in addition to traditional compressed air, this greatly expands the applications our mills can accommodate.

Powder Blending

Fluid Energy provides a great variety of blending services and capabilities for dry powders. Fluid Energy has both pilot and production size ribbon and paddle blenders to handle the most precise dry blending requirements. These blenders range in size from 14 to 200 cubic feet. Fluid Energy engineers and production personnel develop customized procedures for blending in consultation with our customers. Blenders are available in both carbon steel for technical grade products and stainless steel for food grade and other specialty applications. In addition, a wide variety of packaging options are available.

For blends that require more intense agitation, Fluid Energy has incorporated high speed choppers into our systems. During mixing, the ribbons continuously sweep product across the choppers for a high quality, more thorough mix. The rotating choppers impact the product at a high rate of speed. This added feature increases Fluid Energy’s capabilities to give customers a wider variety of blending options.

Most of Fluid Energy’s blenders are equipped with spray nozzles that are used to add liquids continually during the blending cycle. By adding liquid during the dynamic phase of blending, the result is a more homogenous combination of the liquid and dry powders. Often times the liquid forms a coating on the surface of the powder, encapsulating the particles. In addition, some powders can be heated to melt and form a coating on a substrate. The coating levels and blend ratios, coupled with the proper application technique, must be taken into consideration. Fluid Energy has years of experience with many powders and liquids to provide the technical testing assistance needed to complete your coating and encapsulation requirements.

Jet Blending

When a blending application requires more than a ribbon or paddle blender can handle, Fluid Energy jet mills provide the ultimate in blending results. Jet mills can be operated at low pressures to avoid particle size reduction but still retain the turbulence needed for the ultimate blend. Often times an added jet blending step is used to guarantee homogeneity. An added benefit of jet mill blending is that it can be scaled down to very small, lab size batches for testing and product sampling.

Flash Drying

As mentioned before, Fluid Energy strive to solve all your powder processing needs and with that we understand that our customer may be looking to reduce the moisture content of the raw material.

Using our THERMAJET™ recirculating loop flash drying technology, we can produce a dry, discrete particle from a filter cake centrifuge or slurry feed. Heat-sensitive materials are dried without degradation due to short residence time and evaporative cooling. Recirculating gases and deagglomeration achieve moisture specifications at less than 0.1%

Our THERMAJET Flash Drying Processing can be used for many applications including:

  • Chemicals
  • Polymers
  • Pigments
  • Ceramics
  • Sludges
  • Minerals

Crushing and Screening

Not every powder processing need can be solved with a jet mill, blender or flash dryer and that is why Fluid Energy offers Screening, Crushing, Mechanical Milling and many other powder processing options to meet our customers specific needs.
