Jet Mill Manufacturer for Ultrafine Grinding

Jet Mill for Ultrafine Powder Processing

Product Introduction

JETER Jet Mill is an ultrafine grinding system designed for applications requiring precise particle size control, high product purity and low contamination.

The mill uses high-velocity compressed air or process gas to accelerate particles and achieve size reduction through particle-to-particle collision. Unlike conventional mechanical mills, no grinding media are required, helping reduce wear-related contamination and making the technology suitable for high-value powders.

JETER Jet Mills are used for pharmaceutical and API micronization, chemical and specialty powders, battery materials, food ingredients, minerals and advanced materials.

For applications with specific D50, D90, capacity or purity requirements, material testing can be carried out to determine the appropriate Jet Mill configuration.

Key Advantages

Ultrafine Grinding

Designed for fine and ultrafine powder processing where controlled particle size is required.

Low Contamination

No conventional grinding media are used, reducing the risk of contamination caused by media wear.

Precise Particle Size Control

Grinding conditions can be adjusted according to material characteristics and the required particle size distribution.

Low-Temperature Processing

The grinding mechanism avoids direct mechanical grinding contact, making Jet Milling suitable for many temperature-sensitive materials.

No Grinding Media

Particle size reduction is achieved primarily through high-velocity gas flow and particle-to-particle collision.

Compact Design

A compact grinding configuration simplifies installation, operation and routine maintenance.

Flexible Gas Selection

Compressed air can be used for general applications, while nitrogen or another suitable inert gas can be considered for oxygen-sensitive materials.

How Does a Jet Mill Work?

A Jet Mill uses high-velocity compressed air or process gas to reduce particle size inside a grinding chamber.

Feed material enters the grinding chamber through a controlled feeding system. High-pressure gas is introduced through specially designed nozzles, generating high-velocity gas streams that accelerate the particles.

The accelerated particles collide with each other repeatedly. These particle-to-particle impacts cause the particles to fracture and progressively reduce in size without grinding media.

Fine particles are carried out of the grinding zone with the gas flow, while coarser particles remain in the grinding area for further size reduction.

The final grinding performance is influenced by:

• Grinding gas pressure

• Gas flow rate

• Feed rate

• Feed particle size

• Material hardness and density

• Material moisture

• Target particle size

• Classification conditions

For critical applications, JETER recommends material testing before final equipment selection.

Particle Size Control

Particle size in a Jet Mill is controlled by the interaction between material properties and operating conditions.

Key factors include:

Grinding Pressure
Influences particle acceleration and collision intensity.

Gas Flow
Affects particle transport and separation within the grinding system.

Feed Rate
Influences particle concentration and grinding efficiency.

Feed Size
A suitable and stable feed size helps maintain consistent grinding conditions.

Material Properties
Hardness, density, brittleness, morphology and moisture can significantly affect grinding performance.

Classification
Classification conditions determine which particles leave the grinding system and which remain for further grinding.

For applications requiring a defined D50, D90 or narrow particle size distribution, testing with the actual material is recommended.

Applications

Pharmaceutical & API Micronization

Jet Mills are widely considered for pharmaceutical powders and APIs where particle size control, product purity and low contamination are important.

Typical applications include:

• APIs

• Pharmaceutical intermediates

• Fine pharmaceutical powders

• Selected heat-sensitive materials

Equipment configuration can be adapted according to cleaning, containment and material-contact requirements.

Battery & New Energy Materials

Jet Milling can be considered for selected battery and advanced energy materials requiring controlled particle size and contamination prevention.

The appropriate configuration depends on material hardness, target PSD, oxidation sensitivity, moisture sensitivity and production capacity.

For oxygen-sensitive materials, inert gas operation can be considered where appropriate.

Chemical & Specialty Chemicals

Jet Mills are suitable for selected fine chemicals, specialty powders, pigments, dyes and functional materials where ultrafine particle size and product purity are important.

Food & Natural Products

For suitable materials, Jet Mills can be used for food ingredients, nutritional powders, natural products and other powders requiring fine particle size and clean processing.

Minerals & Advanced Materials

Selected minerals, ceramics and inorganic powders can be processed when fine particle size and low contamination are required.

Material hardness, feed size and target PSD should be evaluated before equipment selection.
