Vorti-Siv Vibratory Sieves for wet and dry applications

Vorti-Siv Vibratory Sieve, Pilot Series

Multiple Uses

The Vorti-Siv pilot model RBF-15 is one of the most efficient sieving and straining machines on the market. The side-discharge is totally enclosed, heavily constructed and driven by a standard explosion proof, single or three-phase 1 H.P. motor. An optional air-operated unit is also available. The standard discharge height is 30", however, the electric version is available down to 24" and the pneumatic version to 18". The RBF-15 is extremely effective on many wet and dry applications. Popular uses include: quality control check screening of powders, liquid straining, product reclamation, and particle size separation.

Successfully processed products include:lactose, sugar, nuts, dental powders, antibiotics, powder, flour, cosmetics, pharmaceuticals, chocolate, powdered milk, tablets, vitamins, aspirin, spices, media, food powder, hormones, paint, ink, paper coatings, powdered metals, resins, adhesives, latex, grinding media, powder coatings, solder paste and an unlimited number of highly specialized applications.

Gyratory Action Mobility

The Vorti-Siv Pilot Unit uses a unique gyratory screening-action generated by an adjustable off-balance flywheel, which is powered by a direct drive 1 H.P., 3450 RPM or 1750 RPM motor. Any point of the screen surface moves in a circular orbit, but the screen itself does not rotate. Only the top section of this unit gyrates while the bottom is stationary. Most models are mounted on three or four castors, for easy in-plant mobility. Four quick release toggle or pan clamps allow easy dismountability for clean-up or product changeover.

Oversize

Applications with large amounts of oversize may require a scroll mounted to the screen. This enables a continuous and uniform discharge of material from the screen surface. Scroll sizes will vary with each application. For example, a full scroll allows greater product retention time on the screen. A half or finger scroll is utilized for free flowing material and provides greater screen surface area.

RBF Screening Element

Vorti-Siv RBF-15 easy dismountable screening element adapts itself to in-pant screening control; thereby increasing production and reducing outside screening cost. Nylon and stainless steel screening are immediately available from Vorti-Siv. Sizes range from 2 mesh to five micron. All screens and screening elements are interchangeable with other Vorti-Siv Models. Vorti-Siv equipment may be screen stacked for two to eight decks.

Contact Parts

All Vorti-Siv product contact parts constructed of 18 gauge 304, 316, or 316L grade stainless steel. Polished finishes to customer specifications. Contact parts consist of four items: main rim, base rim, discharge funnel and screen element. Two additional sanitary designs are available on request.

RBF-15/24 3450RPM High Speed Stainless Sieve

Includes: Standard 24″ diameter (Sweco-type) contact parts. Adapters available in 18", 24", 30", 36" and 48".

RVM-E Series Applications: From Pharmaceutical to Powder Coating

The RVM-15E with a 15" screen diameter and the larger RVM-22E, RVM-30E, RVM-36E, RVM-48E, which utilize 22", 30", 36" & 48" screen diameters are five of the most efficient and compact sieving and straining machines made. These center-discharge units are extremely effective on many wet or dry applications. Popular uses include quality control check screening of powders, liquid straining, product reclamation, and particle size separation.

Successfully processed products include:paint ink, cosmetics, paper coatings, powdered metals, resins, adhesives, latex, grinding media, foods, powder coatings, lactose, sugar, salt, nuts, dental powders, antibiotics, powder, flour, pharmaceuticals, chocolate, powdered milk, tablets, vitamins, aspirin, spices and an unlimited number of highly specialized applications.

Compact Drum Sifter Flexibility

The economical RVM-15E, RVM-22E, RVM-36E and RVM-48E models are typically utilized as compact drum or hopper sieves. The standard center discharge of each model, along with a portable Vorti-Siv made heavy duty stand with swivel locking casters, enable efficient container to container screening. The stand is available in all discharge heights or with adjustable legs.

Oversize Discharge Option

Applications with large amounts of oversize may require a scroll mounted to a raised screen. This enables a continuous and uniform discharge of material from the screen surface. Scroll sizes will vary with each application. For example, a full scroll allows greater product retention time on the screen. A half or finger scroll is utilized for free flowing material and greater throughputs. Typically, an 1800 RPM motor is specified for oversize removal.
