Russell Finex's innovative ultrasonic sieve deblinding system, known as the patented Vibrasonic® Deblinding System (VDS), eliminates the blinding and blocking of mesh. It has revolutionized the screening of difficult powders on sieve meshes, allowing accurate separation down to 20µm. It also increases screening capacities and reduces mesh breakage.
The Vibrasonic® Deblinding System has been developed to be a flexible, retrofit system that can be used in any industry on any vibratory sieve. It is a tuned system comprising of a control box, providing power to drive an ultrasonic probe that is fitted to a specially designed mesh frame. Each component works in unison to provide a frictionless mesh screen to prevent mesh blinding.
Mesh frame options
The BX system - The BX system consists of a self supported screen and Velocity Transfer Plate (VTP), providing even activity throughout the screen while also providing a solid connection for the probe.
The Spiroscreen™ - This patented design is especially suited to larger diameter mesh frames and ensures maximum capacities are achieved on screens up to 2m in diameter.

Vibrowest turbosonic system allows separations of light powders with meshes ranging from 0,250 mm to 0,025 mm (25 micron).
Some powders, due to their granulometry, light bulk density and physical features, can not be sieved only with the mechanical movement of the separator. The turbosonic system allows the sieving thanks to the creation of an additional ultrasonic frequency vibration straight on the wire of the sieving mesh.
ADVANTAGES
Productivity:
better sieving results are reached combining mechanical and ultrasonic vibrations.
Performance:
higher throughputs and screening efficiency, even for materials which are difficult to screen.
Maintenance:
prevent blinding of fine mesh, keep constantly clean the screening surface and avoid screen clogging;
guarantee a longer screen life.
Set Up
The automatic frequency control selects automatically the right frequency for the mesh.

FMC Technologies' screening solutions meet the need for numerous scalping, separating, sizing, de-dusting and de-watering applications. Strategic design enhancements provide effective, economical solutions for some of the most difficult screening applications. FMC Technologies' SyntronÒ screens accomodate a multitude of materials, operating conditions and capacities.
From coal to food processing, to plastics, pharmaceuticals and other processes, Syntron screening feeders are employed to scalp, separate, size, de-dust and de-water bulk products. Powered by highly efficient electromagnetic drives which provide gentle handling with minimal product degradation, Syntron screening feeders have no moving parts, which means no lubrication is required and ongoing maintenance is minimal. Units range in size from a tiny, three-inch-wide pill de-duster to the massive four-foot-wide models used in heavy industry. FMC Technologies also offers electromechanical designs for high-tonnage screening of coarse materials.
With more than 60 years of proven performance, Syntron vibrating screens provide effective and efficient solutions for difficult screening challenges. Syntron screens are on the job in the mining, aggregate, asphalt, pulp and paper, chemical handling, food processing, glass and sewage treatment industries. These screens feature vigorous high-speed elliptical and/or circular vibration that keeps loads lively for accelerated separation, minimizing plugging and blinding. Syntron vibrating screens require only minimal routine maintenance which can be performed with minimal downtime since vibrator parts are quickly detachable from the vibrating screen.

Sandvik screens for scalping, separating and sizing aggregates, minerals and coal come in several different types and a wide range of sizes. Products include robust vibrating grizzlies and scalpers, inclined screens, horizontal screens and roller screens. We offer both individual units and complete systems, as well as expert advice on choosing the right screen for the job.
|
|
Applications:
These screening machines can be used universally for test screening or to produce between 2 and 4 screen fractions. A good screening effect is achieved by the circular vibration in the vertical plane.
Design:These dustproof machines are made of standard or stainless steel and activated by one or two maintenance-free vibrating motors with adjustable out-of-balance force.
Outstanding advantages:The special vibrator design permits different vibration characteristics, e.g. for gentle screening, long residence times, high throughputs or difficult-to-screen products.
Models and accessories: Cleaning of the screen cloth can be assisted by a ball rapper for small mesh sizes. Stands are available.

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.
