What is an Air Jet Sieving Machine?

The Air Jet Sieving Machine is a laboratory instrument designed specifically for sieving powder and dry grain products. The machine is suitable for sieving materials with particle sizes between 5 µm to 5mm. It is a non-mechanical sieving method that utilizes the principle of air jet sieve to separate particles based on their size and grading.

Unlike traditional sieving techniques such as vibrational, horizontal, or tap sieving, air jet sieving relies on the movement of particles through a sieve mesh using streams of air. The machine generates controlled air jets that propel the particles through the sieve, facilitating separation based on size.

By utilizing air jets instead of mechanical motion, air jet sieving offers distinct advantages. It eliminates the risk of sample contamination or damage from mechanical vibrations, ensuring accurate and reliable results. It also enables efficient deagglomeration of particles and purifies the sieve mesh during the sieving process.

The air jet sieving method is particularly suitable for fine powders and granular materials. It provides a non-invasive way to analyze particle size distribution without subjecting the sample to harsh mechanical forces. The air jet sieve machine offers a precise and efficient solution for particle size analysis in various laboratory applications.

This machine offers several advantages over traditional sieving methods. It provides fast and efficient sieving, allowing for high sample throughput. It also eliminates the need for manual shaking or tapping of the sieve, reducing operator fatigue and ensuring consistent results. Additionally, the machine can be equipped with various sieve sizes to accommodate different particle size ranges.

How Does Air Jet Sieving Work?

Air Jet Sieving machines employ a unique working principle to accurately separate particles based on their size. By utilizing a strong airflow generated through a vacuum cleaner or cyclone system, this non-mechanical sieving method ensures precise results. The process involves several key steps:

1. Connection to a Vacuum Cleaner

The Air Jet Sieve machine is connected to a vacuum cleaner or a cyclone system. This connection creates a negative pressure that generates a strong airflow.

2. Airflow and Nozzle

The machine is equipped with a rotating slotted nozzle positioned beneath the sieve. The negative pressure from the vacuum cleaner generates a powerful jet of air directed onto the sample particles on the sieve mesh through the slotted nozzle.

3. Particle Dispersal

The air jet from the nozzle disperses the particles on the sieve, ensuring that they are evenly distributed. This helps to prevent particle clumping or agglomeration, ensuring accurate sieving results.

4. Deagglomeration and Purification

The strong airflow created by the vacuum cleaner or cyclone system helps deagglomerate the particles. It also serves to continuously purge the sieve mesh, removing any trapped particles or debris that may interfere with the sieving process.

5. Separation of Fine Particles

As the air jet passes through the sieve mesh, particles smaller than the mesh size are transported by the backflow of the air. These finer particles are suctioned away by the vacuum cleaner or directed to the cyclone system, effectively separating them from the desired particle fraction.

6. Collection

The separated fine particles are collected in the cyclone or vacuum cleaner, while the retained particles on the sieve remain for further analysis or disposal.

By utilizing the negative pressure generated by the vacuum cleaner or cyclone system, the Air Jet Sieving machine achieves efficient particle separation, deagglomeration, and purification of the sieve mesh. This working principle ensures reliable and accurate sieving results while maintaining the integrity of the sample.
