Vorti-Siv Vibratory Sieves for wet and dry applications

Vorti-Siv Vibratory Sieve, Production Series

RBF Series Side Discharge

22" , 24" , 30" , 36" , and 40" screen diameter production model using an indirect 1750 RPM motor. Motor is pullied to a fixed or variable speed from 800 to 3000 RPM. Available with traditional Vorti-Siv or standard separator type product contact parts.

Center Discharge RVM Sieves

Models in 15" , 22" , 30" and 36" screen diameters. Driven by a 3450 RPM vibrating electric motor in TENV or explosion proof. Available with bag dump stations or totally enclosed for vacuum-thru sieving. Optional tables supplied in several sizes. All stainless steel models supplied with finishes to 10Ra.

VS Series Side Discharge Separators

30" , 48" & 60" screen diameter production models. Utilizing a direct or indirect 1200 or1750 RPM drive with air suspension or spring mounts. Available in single or multiple decks, with or without oversize chutes.

Vorti-Siv RBF-Series

The Vorti-Siv RBF-3 and RBF-2 are two of the most efficient sieving and straining machines on the market. These totally enclosed units are heavily constructed, driven by explosion proof 5HP (Single or Variable) speed drives utilizing adjustable off-balanced flywheels. Heavy-Duty Bearing Systems enable the units to achieve flywheel speeds of up to 3200 RPM. Quick-release clamps allow easy in-plant dismounting and color changes.

  • All product contact parts are 316 grade stainless steel or PVC plastic.
  • Noncontact parts are available painted, epoxy and teflon powder coated, or in stainless steel.

Nonblinding

Vorti-Siv orbiting movements cause particles of materials to roll in concentric paths over the screen surface, while always staying in contact with the screen. Oversize particles will roll in and out of apertures, and undersizes will roll through. If a great amount of material is placed on the screen surface, the oversize particles will roll to the top. This virtually eliminates blinding. Additional nonblinding options include: the rotary brush assemblies, (nylon brushes teflon wipers and/or stainless blocks above screen), a nonblinding kit (rubber balls below screen) or our SFA ultra-sonic deblinding system.

Oversize

Applications with large amounts of oversize particles will require a raised scroll mounting to be fixed 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 scroll is utilized for free-flowing material and for greater throughputs.

 

Applications

The RBF® units are extremely effective on many wet or dry applications. Models are used for quality control screening, separation of various sized particles, or product reclamation. Each unit has the capability to sieve wet or dry particles when its amplitude is adjusted. Successfully processed products include:

Paints • inks • cosmetics • pharmaceuticals • paper • coatings • powdered metals • resins • adhesives • latexes • media • foods and an unlimited number of highly specialized applications.

Fine powders may require our special Model SFA Ultra-sonic deblinding kit. This system utilizes a 110/220 Volt 200 watt generator, titanium transducer probe and titanium alloy screen adapter. Available on our models in single, double or multiple deck sizes.

Vibrating Motor Sieving & Straining Equipment with Center Discharge

The RVM-15 with a 15" screen diameter and the larger RVM-22, RVM-30, RVM-36 & RVM-48 which utilize 22" , 30" , 36" & 48" screen diameters are four of the most efficient sieving and straining machines made. All units are extremely effective on many wet or dry applications. The RVM design is utilized for applications that require greater capacity motors.

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.

Oversize Discharge Option

Applications with large amounts of oversize may require a scroll mounting 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 greater throughputs. An 1800 RPM motor is specified for continuous discharge.
