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

Jet-O-Mizer

Particle Size Reduction Systems – (0.5-45 Microns)

The JET-O-MIZER is a vertically oriented jet mill with tangential grinding nozzles located at the bottom and static classification occurring at the top. This powder machine is capable of grinding dry powders to 0.5-45 micron averages, this vertical jet mill produces a narrow particle size distribution, consumes less energy and is easy to feed with a wide variety of materials.

  • Sanitary designs for access to gas and product contact areas
  • No blow back, easy feed operation
  • Replaceable grinding nozzles and liners
  • Specialized liners for abrasive applications
  • Combined operations – grinding/blending, grinding/coating
  • Largest range of throughput with models for one gram batches (or rates up to 10,000 lbs. per hour)

Outstanding Efficiency and Versatility in Fine Grinding (0.5 – 45 Microns) and Classification

The JET-O-MIZER jet mill has been developed with many distinct design features to consume less power, provide a greater range of throughput (1 to 12,000 lb/hr) and ensure exceptional finished product quality. Thorough application engineering allows determination of the ideal operational conditions for your process. Specific raw material characteristics and production requirements are integrated into a complete JET-O-MIZER system.

High-Efficiency Chamber Design

The JET-O-MIZER grinding chamber features an inverted trapezoidal design, which forces the circulating particles to concentrate at the nozzles. This unique design improves grinding efficiency and reduces wear on chamber walls.

Adjustable Classification Zone

The JET-O-MIZER jet mill employs an externally adjustable configuration. This feature controls the velocity gradient to isolate the classification process from the grinding chamber. This patented feature allows efficient control of particle size distribution for multiple products or specifications.

No Attritional Heat

The cooling effect of the grinding fluid completely offsets the slight heat generated during grinding. The JET-O-MIZER jet milling machine is routinely used to grind products with critical heat limitations.

Combined Operations

In the JET-O-MIZER system, grinding may be combined with other physical and chemical operations. This saves time, reduces energy and minimizes product handling. While grinding, the JET-O-MIZER can:

  • blend and mix ingredients
  • coat product with waxes, oils and dyes
  • promote chemical reactions (such as oxidization and calcination)
  • inhibit chemical reactions
  • free entrapped solvents
Replaceable Protective Liners

Special alloy, polymer or ceramic liners minimize wear or build-up in strategic areas of the jet mill. This simplifies operation, extends the life of many components and prevents downtime.

Adjustable Classification Zone

Production size JET-O-MIZER jet mill employs an externally adjustable configuration. This feature controls the velocity gradient to isolate the classification process from the grinding chamber. This patented feature allows efficient control of particle size distribution for multiple products or specifications.

Reliable Construction

Custom Processing

Fluid Energy maintains a facility for fine / ultra fine grinding of your material on a contractual basis. Other services include blending, drying and packaging. Our fully equipped QA laboratories are available for moisture, particle size and custom analyses of your products.

Air, steam or gas is introduced into the JET-O-MIZER through specially designed nozzles to create a sonic or supersonic grinding stream. Solid particles of raw feed are injected into this violent, turbulent stream. The high-velocity collisions that result provide thorough and effective pulverization of the feed into smaller particles. The particle stream leaving the reduction chamber flows to the classification zone. As the stream enters the static classifier, the direction of flow is reversed. Properly sized product is entrapped by the viscous drag of the exiting flow and conveyed to collection equipment. Larger particles are recycled to the reduction chamber for further grinding.
