The Cleveland Vibrator Company, along with its affiliate HK Technologies, introduces a new line of ultrasonic screening equipment utilizing dual vibrator drives. This dual motor separator provides for three control variables: vibrator force, frequency, and drive angle. This design concept results in a three dimensional motion thus allowing for greater throughput of difficult to screen products. This distinctive vibratory action coupled with HK Technologies unique ultrasonic deblinding system provides a screener that can handle many difficult screening applications. The transducer is attached to the aluminum rim with the wire cloth attached on the bottom (like a sieve). Unlike competitive products, the ultrasonic vibration transfers from the rim to the wire cloth to facilitate the throughput of fines by introducing high frequency movement to the individual wires. Helps eliminate blinding. This unique transfer increases the life of the wire cloth as traditional methods allow heat from the transducer to prematurely fail the fine wires.
Models are available in 24, and 36" diameter screen sizes. Screen sizes down to 635 mesh (20 micron). All screens are re-screenable.
Cleveland Vibrator also manufactures a complete line of brute force screeners as well as fine powder, laboratory screeners. Ask about our HyBrute, a brute force screener with the addition of ultrasonic deblinding.

Gravel, sand, coal and many basic materials must cover a long path before they are suitable for further processing. Vibration conveyors are an important part of this path. They drain the excavated sand, screen gravel according to grain sizes, take the load off breakers or mills of fine-grained material or assist in the cleaning of wash water. They are particularly for use in the basic materials industry, where vibration conveyors are characterized by their wear-poor, rugged construction and lifetime duration.
Precise screening to grain sizes in the range from 25 µm to 500 mm, high service and temperature resistance, for example in the case of supplying components to the melt furnace in glass production, are also advantages of vibration technology.
