HAVER & BOECKER

HAVER & BOECKER, a leading manufacturer of high-precision wire cloth and screens and ARTECH Ultrasonic Systems AG, a subsidiary of Crest-Holding and specialist in ultrasound technology, are collaborating to provide custom-made ultrasonic screening systems with frequency variation.

HAVER Ultrasonic Screens with ARTECH Frequency Variation.

Your numerous advantages:

• No “hot spots” on the resonator or screen since the resonance frequencies are covered only briefly
• The caking on of powder is prevented with temperature-sensitive powders without loss of throughput
• Longer time periods between the screen’s cleaning cycles
• Longer service life times of the screen mechanics and screen
• No tuning of the ultrasonic mechanics necessary – the current screen mechanics can be retrofitted and tensioned with the ARTECH sound conductor system problem-free
• Frequency variation makes possible the excitation of several screens by a generator – this reduces the necessary investment
• Frequency variation excites the entire structure including the screen, which makes possible the distribution of the sound field over the entire surface, which allows for a high throughput
• Considerable process safety with forced oscillations without phase regulation, the mechanics always oscillate even without resonances – no possibility of generator overload
• Converter and HF cable are located outside the powder flow, no caking on the converter is possible
• ATEX certificate for ATEX Zone 20 inside the screening machine as well as for ATEX-Zone 22 outside the screening machine are available
