Air-Jet Sieve for Particle Size Analysis

Air-Jet sieve analysis is used to determine particle size distribution of dry powders. It is ideal for powders less than 60 microns size, that tend to agglomerate in traditional vibratory sieves. Typical particle size distribution handled by the equipment ranges from 20 microns to 5000 microns The Infinita Lab network of testing labs offers the Air-Jet sieve analysis test to its clients in USA and across the world.

Overview

Air-Jet Sieve is another testing method for particles used in size analysis. It is used to identify the size of fine powdery materials and granules. This analysis is achieved by using air to separate and filter particles through a fine mesh sieve without allowing them to clump together.

This testing method is used in various fields such as pharmaceuticals, chemicals, food processing, minerals, and powder technology to accurately determine the sizes of fine particles. This is achieved through the use of air jets, which help separate particles efficiently without allowing them to stick together.

Scope, Applications, and Benefits

Scope

Air-Jet Sieve analysis is used to measure the particle size distribution of fine powders and particulate materials using a controlled air stream and precision sieve system. The method ensures accurate separation of fine particles.

The scope includes:

Determination of fine particle size distribution
Analysis of powders and granular materials
Testing of free-flowing or cohesive powders
Quality control of industrial powders and chemicals
Evaluation of powder processing performance

Applications

Chemical and pigment industries
Food and beverage powders
Mineral and cement powders
Additive manufacturing powders

Benefits

Accurate measurement of fine particles
Prevents particle agglomeration during sieving
Faster analysis compared to traditional sieving
Suitable for cohesive and lightweight powders
Improves quality control in powder processing

Test Process

Sample Preparation

A measured amount of powder sample is placed on a calibrated sieve inside the air-jet sieve apparatus.

Air Jet Dispersion

A controlled stream of air is directed through the sieve to disperse particles and prevent clumping.

Particle Separation

Fine particles pass through the sieve openings while larger particles remain on the sieve surface.

Result Evaluation

The retained and passed particles are measured to determine particle size distribution.

Frequently Asked Questions

Air-Jet Sieve analysis is a particle size testing method used to determine the distribution of fine powders by using a controlled air stream that disperses particles and passes them through precision sieve openings.

Air helps disperse particles and prevents agglomeration, allowing finer particles to pass through the sieve openings more effectively than conventional mechanical sieving methods.

Air-Jet Sieve analysis provides faster results, better dispersion of fine powders, reduced particle agglomeration, and improved accuracy for fine particle size measurement.

Yes, the air dispersion mechanism helps break up cohesive powder clusters, making it effective for materials that are difficult to analyze with traditional mechanical sieving.

Particle size distribution affects properties such as flowability, reactivity, mixing behavior, and product performance, making it an important parameter in powder processing and quality control.
