8”, 10”, & 12” Lab ModelsThe VORTI-SIV Lab Model RBF-10 (10" screendiameter and RBF-12 (12” screen diameter) are twoof the most advanced small batch sieving machineson the market. The units are totally enclosed,heavily constructed, and weigh 90 lbs. They aredriven by a 1/3 HP open frame, TENV, TEFC, orexplosion proof 3450 RPM electric motor. Theexplosion proof or TEFC option adds 2”-6” to theRBF overall height. Alternatively, a multi-vane airmotor is available for pneumatic applications. Themodel RBF-8 is available for adapting to certifiedA.S.T.M. 8” diameter stainless steel or brass testsieves. These models are extremely effective onmany wet and dry products.

Successfully processed products include:Paint, Inks, Cosmetics, Dental Materials,Pharmaceuticals, Paper Coatings, Powered Metals,Resins, Adhesives, Latex’s, Grinding Media, Foods,Powder Coatings, and an unlimited number ofhighly specialized applications.

GYRATORY ACTION-MOBILITYVORTI-SIV Lab Models use a unique gyratoryscreening-action generated by two adjustableoff-balance flywheel weight, which are powered bya direct drive 1/3 HP, 3450 RPM motor. Any pointon the screen surface moves in a circular orbit, butthe screen itself does not rotate. The top section ofthese units gyrates while the bottom is stationary.All models are constructed on rubber pads, thusenabling easy table mounting. Quick release clamps(3 required) enable easy dismountability forclean-up and changeover.

MULTIPLE DECKS/CONTINUOUSDISCHARGEApplications with several particle sizes may requiremultiple stacked screen elements. The RBF-10 andthe RBF-12 are constructed to enable up to eight (8)additional decks. Decks require a rim locking bandfor each screen. The standard screen rim height is 2”or 3” for each stacked screen. An oversize dischargechute with a deflection scroll is utilized forcontinuous large particle removal.

SPECIAL APPLICATIONSThe RBF® Labunits are widelyused for manycustomizedapplications.Shown is ModelRBF-12 withthree screendecks andcontinuousoversize chutes.A stainless steelself-feedhopper withslide gate ismounted abovethe RBF-12. Thevibration fromthe base of thesieve istransmitteddirectly to thefeed hopper.A scoop feedcover is utilizedto minimizedust from thetop screen.Three SFA® Ultra-sonic deblinding kits are attachedto each screen deck to prevent blinding at finermesh sizes.

RBF®-LABThe VORTI-SIV Lab Units’ dismountable and quickchange screening element adapts itself to inplantscreening control. Removable stainless steel andnylon screening are immediately available fromVORTI-SIV. Sizes range from 10mm to 2 micron. AllVORTI-SIV Lab equipment is totally enclosed andavailable with optional removable or welded dome,scoop feed lid, or special dust covers.

TWO CONTACT PARTSRemovable labmodel stainlesssteel productcontact parts.Shown is a shallowdischarge funnel(right) and a main3” rim withsoldered or bonded screen element (left). With onlytwo contact parts, it enables easy product clean-upand color change-over.

ROTATING BRUSHESStandard deckLab model optionis a rotary brushassembly utilizingwipers ornylon brushes.Brushes/wipersare used to slowscreen blinding or

break loose agglomerates. Bumpers contacting thegyrating rim cause the assembly to rotate across thescreen surface.
