Blinding Control System helps screen sticky, fine powders.

Press Release Summary:

Designed to minimize blinding and bridging when screening difficult or sticky materials, Ultrasonex(TM) screens through meshes as fine as 20 µm. Transducer probe applies ultrasonic vibration directly to screening mesh in addition to vibratory motion of screener. Fully detachable probe incorporates titanium core for non-wear on contact surfaces. Featuring touch panel controls, Ultrasonex is available on new screeners and can be field retrofitted to existing screeners.

Ultrasonex(TM) Blinding Control System From Rotex Increases Screening Accuracy of Sticky, Fine Powders

CINCINNATI, OH (November 11, 2005) - The Ultrasonex(TM) Blinding Control System from Rotex, Inc. is a field proven system for reducing blinding and bridging when screening difficult or sticky materials such as metal powders, powder paints, pharmaceuticals, powder coatings, plastic resins, toner powder, food, and various chemicals. It is available on new screeners from Rotex, and can be field retrofitted to existing ROTEX® screeners.

The system is capable of screening through meshes as fine as 20µm at unusually high capacity and efficiency. By minimizing mesh blinding and bridging, the Ultrasonex System ensures that powders are screened through the correct aperture size required, providing accurate separations, higher throughput, consistent product quality, and longer mesh life.

The system uses a transducer probe to apply ultrasonic vibration directly to the screening mesh. This is in addition to the vibratory motion of the Rotex screener. The Ultrasonex provides a secondary high frequency, low amplitude vibration that reduces mesh blinding, reduces screen tension, and improves screener performance. Its fully detachable ultrasonic probe incorporates a titanium core for high durability and non-wear on contact surfaces.

Freedom from blinding also eliminates the need for scrapers, brushes or rubber balls that can introduce contamination.

The Ultrasonex System's highly efficient control unit is available in 110 or 220 volts, with touch panel controls that enable many of the settings to be easily adjusted by the operator for optimal performance.
