Kason's Air-Lift quick screen change system for circular vibratory screeners allows operators to change screens and gain access to the interior of the unit for cleaning or inspection many times faster than possible using comparable systems.

The lightweight device consists of two vertically mounted air cylinders that are located on opposing sides of any circular separator and affixed to mounting brackets on the lower and upper screening frames.

To operate, a quick-disconnect clamp connecting the frames is removed and a remote air valve is actuated, raising the upper frame. The procedure is reversed to reconnect the frames.

One entire raise/lower cycle including quick-disconnect/connect of the frames, requires only several minutes, reducing downtime during every inspection, cleaning and screen-changing operation. In addition, one operator can now perform what was previously a two-person task, depending on screen diameter.

Other safety features include a safety lock-out that locks the frames in the open or closed position when the upper screener housing is raised or lowered, and safety bars that prevent the housing from accidentally descending while in a fully-raised position during screen changes or wash down.

The Air-Lift device is available on any new Kason screener, and can be retrofit to any circular vibratory screener of any make or model from 48" to 84" (1220mm to 2135mm) in diameter, including screeners having single- or multiple-decks, and screens with or without center holes and/or anti-blinding devices.

All Vibroscreen^® separators from 30" to 84" (760mm to 2135mm) diameters in both single- and multi-deck configurations are available with Kason's exclusive "clamshell" option. The hinged lid and/or frames are released via quick-disconnect clamps and held in an open position by gas pistons, allowing rapid screen changes and easy, thorough washdown of all interior surfaces. The Clamshell Lid accepts screens with or without center tensioning construction, and accommodates screen decks with or without anti-blinding devices. The Kason Quick Screen Change Assembly is the only deck-opening device offering all of the above capabilities.

Questi spruzzatori perforati a forma di palla in acciaio inox sono posizionati al termine di tubi in acciaio inox e danno una spruzzatura multi-direzionale di fluidi di lavaggio, rendendo più facile la pulizia dell'interno dei vagli circolari. I tubi fuoriescono dai telai del piano di vagliatura e puntano verso l'alto dalle superfici superiorie. Il loro collegamento flangiato assicura la tenuta stagna dei tubi di alimentazione per il fluido di lavaggio.

VIBROSCREEN^® vibratory screeners for pharmaceutical applications feature clean-in-place spray heads for hands-free wash down. The pharmaceutical screener shown is configured with one gap-free screening deck. Three clean-in-place spray heads are required: one each for the upper, central and lower chambers. Quick-disconnect clamps allow two-minute disassembly of all water supply hoses, clean-in-place spray head fittings, and separator body sections for inspection or screen changes. Unlike traditional circular screen separators, this sifter has no gaps between the mounted screen and the frame wall. It is offered in diameters from 18 to 60" (460 to 1525mm) in all-stainless construction finished to FDA as well as 3-A, BISSC and other sanitary standards.

Il sistema di pulizia a palle della Kason è particolarmente adatto nelle applicazioni di vagliatura di prodotto secco con una granulometria molto precisa. Un telaio di sostegno viene montato sottostante il piano in questione. La vibrazione del vaglio attiva le palle elastomeriche che rimbalzano in continuo contro la superficie inferiore della maglia in questione. L'impatto delle palle fa piegare la maglia, asportando le particelle con dimensioni quasi uguali a quelle del buon prodotto per tenere pulita la maglia.

Gli anelli "Kleen Screen" T impediscono il bloccaggio delle maglie con prodotti collosi o fibrosi. Delle tolleranze calcolate in maniera precisa all'interno del vaglio assieme alla vibrazione inerziale multi planare si abbinano a creare un'azione di trancio che taglia le fibre e raschia via le particelle collose. Questi anelli cavi aiutano ad aumentare il flusso del prodotto sull'intera maglia.

Il dispositivo di pulizia brevettato Kasonic^® permette il setaccio di prodotti con dimensioni di 25 µ su qualsiasi vibrovaglio circolare di diametro fino a 2540 mm. Trasmette frequenze ultrasoniche - regolabili - alla maglia, regolando l'energia richiesta in maniera automatica a seconda dei carichi da vagliare. Funziona con vagli standard, riducendo i costi ed è a sostentamento indipendente, il che prolunga la vita del vaglio.

Il sistema automatico di lubrificazione alimenta i cuscinetti dei motori per 6 a 12 mesi tra sostituzioni del serbatoio. Un flusso continuo di lubrificante pulisce le gole di materiali e lubrificanti vecchi ed usati e minimizza le zone morte di lubrificanti non-utilizzati. In opzione per i vagli VIBROSCREEN con diametri da 1220 mm e più grandi. Può essere installato su qualsiasi vibrovaglio circolare già esistente in un'ora.

All VIBROSCREEN^® circular vibratory screeners from 18" to 100" (460mm to 2540 mm) in diameter are available designed, constructed and finished to industrial, food, dairy, and pharmaceutical standards including FDA, 3-A, BISSC, EEC and others. Sanitary screeners generally offer one or more of the following features:

• Clean-In-Place (CIP) spray nozzles
• Air-Lift or Clamshell quick screen change system
• Rounded corners and ground/polished welds
• Quick-release fittings
• Gap-free screen/frame configuration

L'insieme delle lame pulenti impedisce il bloccaggio delle maglie e migliora le capacità in quanto distrugge gli accumuli e gli agglomerati. L'unità montata indipendentemente permette di regolare l'altezza delle lame sopra la superficie della maglia e della velocità di passaggio da 1 a 15 giri per minuto. Le lame in gomma o le spazzole possono essere fissate alle braccia dell'agitatore.

Il dispositivo di pulizia maglia a quattro lame flessibili è un sistema installato sul lato superiore per prevenire il bloccaggio della maglie da parte di fanghi o peci. L'unità consiste in quattro lame radiali in neoprene che pulisce a fondo il lato superiore della maglia. Ci sono disponibili dei dispositivi di costruzione speciale per i prodotti molto particolari. Il meccanismo viene attivato dalla vibrazione inerziale del vaglio VIBROSCREEN.

Kason gravity-fed and pneumatic in-line screeners in 24", 30" and 40" (610, 760 and 1015mm) diameters are available configured as basic Bag Dump Stations (top), or Bag Dump Stations with Dust Collectors (bottom) that protect the operator and plant environment against dust contamination during manual dumping operations. Ambient air and dust from dumping activities is drawn onto the exterior of two cartridge filters that derive vacuum from a top-mounted exhaust fan. Dust accumulated on the filters' exterior surfaces is dislodged by overcoming continuous negative pressure within the cartridge filters, with positive pressure introduced in short blasts on a timed cycle by pulse jet nozzles. Dislodged material falls into the screener while instant resumption of negative pressure collects any dust generated by the filter cleansing operation. To afford a sufficiently low deck height for manual dumping—and provide space below the screener outlet for connection to mechanical or pneumatic conveyors, process equipment or storage vessels—bag dump stations are normally specified in combination with Kason's Flo-Thru low profile screener. Screeners configured for bag dumping with or without dust collection are available to industrial, food, dairy and pharmaceutical standards including 3-A, FDA and BISSC.

Il coperchio a tenuta stagna rende la maglia superiore visibile per l'ispezione, permette l'utente di controllare il flusso del prodotto sulla maglia e rende accessibile il piano superiore.

High Capacity "KASCADE" Internal Recycle Screening Decks

"KASCADE" Internal Recycle Screening Decks operate in conjunction with conventional screening decks to increase the capacity of new or existing circular vibratory screeners by 60 to 160 percent.

Available new or as retrofit kits, KASCADE screening decks are generally specified for new applications where space is restricted since diameters are significantly smaller than those of conventional screeners having equivalent capacity, or for retrofit applications to increase capacity and efficiency (minimized "carry-over" and ejection of on-size material) at substantially lower cost than purchasing new equipment.

Positioned directly above conventional screening decks, a KASCADE deck has a screen of identical mesh, but of slightly smaller diameter than the conventional screen below, allowing for a 360° annular gap at the screen's periphery. The KASCADE deck is fed with more material than it can efficiently screen, with two results: 1) On-size material falling through the screen of the KASCADE deck is funneled through a hole in the center of the lower conventional screen to the machine's discharge outlet, and 2) The overflow of on-size material plus all oversize material cascade over the screen's periphery, onto a conventional screen of equal mesh that scalps the balance of material in normal fashion.

Kason offers KASCADE screening decks in one-, two-, or three-deck configurations (single-deck shown), in diameters from 40" to 100" (1025mm to 2550mm) to scalp, dedust, and/or classify up to 91 metric tons/h of free-flowing bulk material.

Available to 3A, USDA, FDA, BISSC and other sanitary standards, KASCADE screening decks can be disassembled rapidly for thorough wash-down.
