NEXOPART UFA. Ultrasonic frequency variation.


For successful sieving of fine powders with critical separation cuts of ≤ 300 µm NEXOPART offers you the ultrasonic frequency variation for test sieves. An important tool for you if you want to analyze your fine bulk material using a vibrating sieve shaker.  With a few simple steps you can excite the sieve mesh with a continuously varying ultrasonic frequency
 
  1. step: Tighten the clamping ring around your NEXOPART test sieve. 
  2.  step: Mount the converter.
  3. step: connect generator and switch on.

Product overview ultrasonic frequency variation

Take a look at how the ultrasonic frequency variation simplifies your laboratory work

The high-frequency vibrations that are generated reduce the frictional resistance between particles and sieve mesh. Your result:
 
  • minimized clogging tendency,
  • destruction of agglomerates,
  • higher sieving capacity and a shortened sieving time,
  • low mechanical load on the sieve bottom + side effect cleaning of the sieve mesh,
  • Parallel handling of several test sieves with only one generator (enables connection with two converters, twin operation)
For some bulk materials, sieving with vibration sieving machines becomes possible for the first time.

Analog or digital ultrasonic frequency variation.


As a "plug-and-play" solution, you can attach the NEXOPART UFA in an analog or digital version conveniently, quickly and safely to all standard test sieves. The digital device allows you to excite several test sieves simultaneously with only one generator. With the help of the twin unit, it is even possible to connect two converters.

FAQ about a test sieve

What is a test sieve?

L


A test sieve is a tool for determining particle sizes. It consists of a sieve with defined mesh sizes. In laboratory-based applications, the particle size of a material is analyzed and classified as “smaller” or “larger” using the specified opening width of a test sieve. At the same time, the material is separated and divided into new fractions. The method used with the test sieve is called sieve analysis or test sieving.

Why do you need a test sieve?

L


A test sieve is mainly used in quality testing to ensure that materials meet the required specifications. A test sieve is used in various industries such as the food industry, pharmaceutical laboratories and the building materials industry. The use of test sieves ensures that users receive clear and reliable information about particle distribution and sizes. This is crucial for the processing and use of materials.

How expensive is a test sieve?

L


The price of a test sieve can vary depending on the size and material. You can view the prices of NEXOPART test sieves in the product details of the respective models as a registered customer
in our store.

How is a test sieve properly maintained?

L


A test sieve should be cleaned after sieving. For a test sieve with fine mesh < 250 µm, cleaning in an ultrasonic bath is recommended. Alternatively, it can be cleaned with a fine brush; a brush can also be used for coarse mesh types. An test sieve should dry well. Drying can take place in a laboratory oven at no more than 120 °C, whereby the temperature resistance of the sieve should be taken into account.

What material is a test sieve made of?

L


A test sieve can be made from various materials, including stainless steel, aluminum or wood. However, stainless steel is the most frequently used material for test sieves due to its durability and corrosion resistance.

What is the ISO 3310 standard?

L


The ISO 3310 standard is an international standard that specifies the technical requirements for the manufacture and use of test sieves. The ISO 3310 standard describes the design, mesh size, materials and test methods for a test sieve used in quality testing. The aim of the standard is to ensure that test sieving of bulk materials is consistent and reproducible and thus provides reliable results. Companies should adhere to this standard to ensure the quality and accuracy of their laboratory analysis.

How can you check that a test sieve complies with ISO 3310?

L


At NEXOPART, you will receive proof or have the option of a certification confirming that your test sieve complies with the ISO 3310 standard.
