What are sieve shakers and sieve machines?
L
Sieve shakers and sieve machines are mechanical devices for separating and classifying particles of different grain sizes. They enable precise and reproducible particle analysis, which is indispensable in everyday laboratory work.
EML series from NEXOPART – Electromagnetic laboratory machine:
L
The vibrating sieve shakers from the NXOPART EML series work according to the principle of 3D sieving. EML stands for electromagnetic laboratory machine. A set of standardized sieves is arranged one above the other in a sieve tower on the test sieve shaker. The samples are subjected to three-dimensional sieving through vibration, oscillation, and throwing movements. The particles move both vertically and horizontally. This 3D movement ensures that all particles on the sieves are thrown upwards and pass through the appropriate sieve opening as they fall.
Special process: Tap sieving (RO-TAP®)
L
A special form of three-dimensional sieving is tap sieving, also known as RO-TAP® sieving. This process was developed by W.S. TYLER® and is specified as standard in many international standards, such as the FEPA standard.
Unlike classic 3D sieving, RO-TAP® moves the sieve tower in a horizontal, elliptical motion. In addition, a tapping impulse is applied to the top of the sieving tower with each rotation. This combination improves separation, especially for materials that are difficult to sieve, and ensures greater precision.

Air jet sieve machine e200 LS – the solution for fine and agglomerating particles:
L
Classic 3D sieving reaches its limits with very fine, oily, or highly agglomerating particles. This is where air jet sieve machine comes in, which is particularly well established in the cement industry.
In contrast to sieving with a sieve tower, the process begins with the finest test sieve. The test sieve is closed with a lid and an industrial vacuum cleaner creates negative pressure inside the machine. The suction effect presses the sample material onto the sieve bottom. At the same time, a rotating slot nozzle blows air through the sieve mesh from below. This air movement swirls the sieved material and loosens stuck particles. This allows even heavily agglomerated particles to be reliably separated.

FAQ
Why are sieve shakers and sieve machines indispensable for laboratories and quality control?
L
1. Reproducibility of results:
Manual sieving is subjective and can vary depending on the operator. Sieve shakers and sieve machines ensure consistent sample handling through standardized movements, which significantly increases the reproducibility of results.
2. Time savings and efficiency:
Automated sieving processes significantly reduce the time required. While manual sieving can take several minutes to hours, sieve shakers and sieve machines complete this task in a fraction of the time – with greater precision.
3. Improved accuracy:
The uniform and controlled movement of the sieves separates particles more efficiently. This leads to a more accurate determination of particle size distribution, which is essential for many scientific questions.
4. Versatility and flexibility:
Sieve shaker and sieve machines are compatible with different sieve sizes and types. This allows them to be adapted to a wide variety of sample types and requirements – from fine powders to coarse granules.
5. Documentation and reproducibility:
Modern sieve shakers and sieve machines often feature digital controls and interfaces that enable precise documentation of sieving parameters. This supports quality assurance and facilitates compliance with laboratory standards and norms.

How do sieve shakers and sieve machines improve laboratory testing?
L
1. Standardization of the sieving process:
Sieve shakers and sieve machines perform the sieving process using fixed parameters such as amplitude, frequency, and duration. This ensures that sample handling remains reproducible and independent of the operator. This standardization ensures valid and comparable results over time and between laboratories.
2. Minimization of sample loss and contamination:
Manual sieving carries risks such as sample loss and contamination from environmental influences. Sieve shakers and sieve machines operate in closed systems that minimize sample contact with the environment. They are made of easy-to-clean materials, which prevents cross-contamination – particularly important in pharmaceutical and chemical analysis.
3. Precise particle size analysis:
Particle size distribution is a key parameter in many sciences. It influences the physical, chemical, and mechanical properties of materials. Sieve shakers and sieve machines separate particles precisely according to size, thus creating the basis for precise analyses. The use of standardized sieves (e.g., according to ISO 3310-1) and controlled sieve movement ensure that the results are highly accurate and internationally comparable.
4. Optimization of process parameters
In research and development, you can specifically influence material properties. Particle size distribution helps to optimize grinding degree, mixing ratios and drying times. Sieve shakers and sieve machines deliver this data quickly and reliably. This allows you to shorten development cycles and increase product quality.

Practical tips for using sieve shakers and sieve machines:
- Clean laboratory environment: Only tested, calibrated sieve shakers and sieve machines should be used
- Sample preparation: Avoid samples that are too small/too large, avoid overfilling the sieves, choose the correct division method based on the “quartering and coning” model, e.g., by using sample dividers
- For vibrating sieve shakers, clamp the sieve tower evenly on both sides: If the clamping nuts come loose during sieving, stop sieving, reconnect the sieves, and clamp the nuts tightly again + observe the minimum sieve tower height (min. 3 analytical sieves + sieve pan).
- Observe the order of the mesh sizes: From coarse to fine.
- Correct setting of the sieve shaker: Set a higher amplitude (1.2 - 2 mm) for coarse materials and a lower amplitude (0.5 - 1.0 mm) for powders and fine materials.
- Sieve selection: Use sieves with suitable mesh sizes according to the expected particle sizes.
- Parameter optimization: Adjust the frequency, amplitude and sieve time to the material properties in order to achieve optimum sieving results.
- Regular maintenance: Clean and check sieve shakers and sieve machines regularly to ensure consistent performance.
- Automatic test sieve cleaning: The NEXOPART e200 LS air jet sieve machine has an “automatic test sieve cleaning” option in its menu selection. Insert the analytical sieve upside down, start the sieving process and brush the sieve bottom with a brush. This loosens particles, which are then discarded without entering the environment – ideal for materials that are hazardous to health.
- Documentation: Document all parameters and results to ensure traceability and quality assurance – this saves time and standardizes processes.
