Nutation vibrating sifters

With the RITEC vibrating screening machines of the TN range you will be able to sort your powders and aggregates with optimal efficiency.

Our range adapts to your production needs, offering you dimensions ranging from diameter 400 to diameter 1800 with a reduced space requirement ranging from 0.125m² to 2.5m². And for higher requirements, RITEC offers an exclusive TN 1800 dual-flow screening machine.

TN screening machines are manufactured according to your production requirements: in steel, 304L stainless steel, especially for foodstuffs, or 316L stainless steel for the most corrosive products.


Classify first of all!

Do you need to separate your inputs into many fractions? Our screening machines are versatile and can be adapted to your requirements.

The TN range of screening machines can go up to 4 decks to offer you an equipment of 4 different screens and thus achieve up to 5 fractions in continuous.


The salsa from the sieve "shaker"....

Because not all materials have the same characteristics, not all materials react in the same way to vibrations.

To optimize your throughput, the TN range of screening machines are nutation and therefore vibrate in 3 dimensions.

You have the possibility to control the movement of the vibration and thus obtain a great diversity of vibration most simply in the world: the vibratory movements are modified by moving counterweights positioned on an unbalanced motor.

Moving the counterweights has never been easier: you don't need tools or disassemble your machine. Access is fast for maximum efficiency.



To further improve your material throughput, we offer you the option of cleaning systems that will "unclog" the screen as it is used.

We mainly offer two cleaning techniques that have proven their efficiency and robustness:

cleaning by Kleeners: the lower part of the fabric is cleaned by a system of polypropylene cones placed on a perforated stainless steel sheet. The cones, which rotate thanks to the vibrations of the machine, keep the fabric clean by constantly scraping the screen. This system is particularly suitable for screening fibrous or spherical materials that can block the meshes during the screening process. Kleeners cleaning also improves separation in liquid media.

ball cleaning: cleaning system of the lower part of the fabric made up of elastomer bales that bounce off a perforated stainless steel sheet. This system is especially recommended in case of the presence of fine products that can stick to the fabric threads.

We can also offer you a brush cleaning system that can be relevant in certain very specific cases, such as in the case of particularly sticky products or products that tend to stick together. This system is placed directly on the screen and the rotation of the brushes is carried out thanks to the three-dimensional movements of the screener.

Finally, we also offer an ultrasonic cleaning system. Do not hesitate to contact us for more information.
