When it comes to sieving fine powders, the air jet sieve emerges as the preferred choice to effectively manage extremely fine particles that tend to agglomerate and clog traditional sieves. The e200 LS, utilising the innovative air jet principle, delivers exceptional performance with these challenging materials.

The effectiveness of the e200 LS is attributed to two key components: a rotating slotted nozzle within the sieving chamber and an industrial vacuum cleaner that is connected to the chamber.

Upon activation of the vacuum cleaner, a vacuum is generated inside the sieving chamber. The design of the rotating slotted nozzle, featuring extremely narrow openings, accelerates the incoming air, directing it at high speed against the sieve fabric from below.

This action propels the particles on the sieve upwards, creating brief yet forceful contact with the acrylic glass cover.

This contact facilitates rapid dispersion of the particles before they are drawn downward through the sieve apertures by the suction of the vacuum cleaner.

Reliable Results

Coarse material remains on the sieve and is re-weighed at the conclusion of the sieving process. The automatic underpressure controller, along with precise specification of sieving-relevant parameters, ensures that reproducible results are consistently achieved.

With its advanced design and operational efficiency, the air jet sieve stands out as a reliable solution for those seeking optimal results in fine powder sieving.

Efficient Sieving Process

The system is designed to conduct the sieving process one test sieve at a time, beginning with the finest mesh opening. This method ensures precise analysis and optimal results for each sample.

• Sample Quantity: Up to 30 grams can be analysed in a single test, allowing precious samples of small quantities to be examined without compromise.

• Test Sieves: A range of test sieves is available, with mesh sizes from 20 µm to 4 mm. This versatility accommodates a wide variety of applications and material types.

This systematic approach to sieving guarantees accurate results while providing flexibility in sample size and mesh selection, making it an ideal solution for diverse analytical needs.

Four high-performance software packages - Lite, Basic, Ultimate, and Security -have been developed to fulfil the diverse analysis needs of all customers. These packages offer a tailored approach to the air jet sieving process, accommodating various processing environments.
