NEW SONIC HORN IMPROVES OPERATING EFFICIENCY AND CONSISTENCY

Neponset, IL, USA – One of the world leaders in bulk material flow technology has introduced a new addition to its family of flow aid products. The MARTIN® Sonic Horn is an acoustic cleaner that reduces system downtime, maintenance, and operating costs, while improving performance and prolonging equipment life. In addition to the low cost of ownership, acoustic cleaning helps avoid structural fatigue or damage, prevents dry particulate build-up, and increases system efficiency. Especially effective around pipes and behind obstacles, sonic energy de-bonds particulates with a 360-degree sweep, cleaning inaccessible parts.

Sonic horns work by producing a low-frequency, high-pressure sound wave, which is created when compressed air flexes a titanium diaphragm in the sound generator. This sound wave is then magnified as it is emitted through the cleaner’s bell. The sound pressure causes dry particulate deposits to resonate and become fluidized, allowing them to be removed by constant gas flow or gravity.

“Acoustic cleaning technology has been providing cost-saving solutions for decades,” commented Jeff Shelton, Multiport Specialist, from Martin Engineering. “It’s a proven technology that can improve throughput and reduce blockages.”

There are 2 models of the sonic horn available. MARTIN® Model D-75 Sonic Horn has a fundamental frequency of 75 Hz and measures 92.07 inches (2339 mm) in length and weighs190 pounds (86.2 kg). This model has a wavelength of 14.75 feet (4.5 m).

The MARTIN® Model D-230 Sonic Horn (230 Hz fundamental frequency) features a wavelength of 4.75 feet (1.5 m) and is 27.5 inches long (698.5 mm). It weighs 54.27 pounds (24.6 kg).

Sonic Horns comply with OSHA dB regulations for vessel interiors, helping manufacturing facilities to comply with emissions regulations. MARTIN® Sonic Horns are well suited for use in boilers, heat exchangers, economizers, bag houses, selective catalytic reduction (SCR) processes, ID fans, electrostatic precipitators (ESP), silos, hoppers, cyclones, and air pre-heaters.

Used in combination with Martin Engineering’s BIG BLASTER® Air Cannon technology, MARTIN® Sonic Horns provide a total cleaning and flow solution. Specific launch dates of this new product may vary slightly, depending on the country / region.

Founded in 1944, Martin Engineering is the world leader in making bulk materials handling cleaner, safer and more productive. The firm is headquartered in Neponset, IL, with global reach from operations in Brazil, China, France, Germany, Indonesia, Mexico, South Africa, Turkey, India and the UK.
