Formula 1 in screening
(Bronschhofen) Just like a Formula 1 racecar on
a particular racetrack, the new screening system from the Swiss company
Telsonic AG adapts to different screening situations. With presets for various types of powder, it
is possible not only to make gains in the hundredths range, but also to achieve
productivity increases amounting to tens of percent. This results
from use of a generator that always optimises the best resonance values for the
particular application. The system is gentle on the material, does not have to
be cleaned nearly as often and is extremely energy-efficient. Existing
screening systems from the Swiss pioneer in ultrasonic screening can be
retrofitted to the new Sonoscreen plus at little additional cost.
"With 16 product-specific presets on the new
Sonoscreen plus, users are sure to find the setting that yields the best
screening results", states Jens Geserik. "Moreover, heavy metal
powders such as tungsten carbide and lightweight pigment powders are each
screened with the lowest possible energy input and thus extremely energy
efficiently", according to the sales agency responsible for Germany. Lightweight
pigment powder with a low melting point can be screened, for instance, with an
energy input of only a few watts using a screen with a diameter of
1.200 mm. This effectively prevents the powder from starting to melt as a
result of the heat generated by a high energy input. In turn, the intervals
between cleanings are extended considerably.
A screening system that adapts
The manufacturer promises a new, flexible screening
technology with varying frequencies. At the start of the screening operation,
the system scans the situation and selects the three best resonance points for
the desired vibration. Since conditions change continually during screening as
a function of the weight or temperature of the material being screened, these
optimal operating points also change. Sonoscreen plus monitors the
continually changing screening situation and adapts the screening process
automatically every minute. Optimising the movement of the fabric in this way
boosts throughput during screening tremendously. "Increases of 30 or 40
percent and even higher are not uncommon", emphasises Geserik, based on
the experience of his customers. Furthermore, products such as green tea that
previously were considered unscreenable can now be screened using ultrasonics.

Users can operate the Sonoscreen plus system easily via a
membrane keyboard. The system stores preset, customer-specific formulas which
can be accessed at the touch of a button. Sonoscreen plus is available for
screen diameters up to 2900 mm. For the first time, multiple screening systems
can be powered by a single generator. HF cable lengths of up to 50 metres are
supplied to enable the generator to be installed in a central location. This
latest development from the Swiss pioneer in ultrasonics is also available with
Atex certifications for use in areas with potentially explosive atmospheres.
Existing Telsonic screening systems can be retrofitted to the new Sonoscreen
plus at little additional cost. Telsonic will be exhibiting the Sonoscreen plus
screening system at the Achema trade fair.
Swiss pioneer and technology leader
The Swiss Telsonic AG is the pioneer in the field of
ultrasonic technology. The company, which was founded in 1966, with
subsidiaries in Germany, England, South-East Europe, China and the USA as well
as a joint venture in India and representatives in many other countries, holds
numerous patents. It applies ultrasonic technology for welding, separation
welding, cleaning and sieving, as well as in chemical processes. Telsonic
patented its ultrasonic screening technology in 1994.
