This technology is applied to promote powder flow and cleaning of vessels. You can replace Vibratory motors, air canons, air evasers with ease. Ultrasonic excitation reduces the wall friction and causes the bulk material to flow continuously or on demand. The movies attached show clearly how well the Ultrasonics work to move even difficult powders.

This Can Be Applied To:

• Silos, Hoppers
• Chutes
• Cyclones
• Funnels
• Vacuum Cans
• Dust Collectors
• Pipelines
• Conveyors
• Mixing Chambers

An Example List of a Diverse Range of Bulk Materials So Far Is:

• Milk powder
• Corundum
• Coating powder
• Phyllosilicate
• Calcium carbonate
• Granulate materials
• Carbon powder
• Ceramics
• Titanium dioxide
• Protein powder
• Chalk

Benefits with Ultrasonics:

(Compared to air fluidization aids, mechanical knockers and other conventional flowing aids).

• Low maintenance cost
• Energy efficiency
• No cracks
• Continuous flow of the bulk material (no production shut down needed)
• Steady throughput
• High control level by the internal Modulating Variable Frequency software (PLC programming possible)

Some important information about the ultrasonic discharging, feeding:

• Ultrasonic works best if the wall thickness of the application is not over 5mm (more has to be tested individually)
• Limitations have to be discovered (16m3 silo – biggest volume positively tested so far)
• ATEX zones 21 (2D), 22 (3D) and 1 (2G), 2 (3G)
