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.

Diese kugelförmiger perforierten Sprühköpfe aus Edelstahl, die am Endevon Edelstahlröhren angebracht werden, beliefern eine multidirektionale Spritzung mit Reinigungs- und Sterilisierungsmitteln und vereinfachen die Reinigung des Innenbereichs von Rundsiebmaschinen. Die Röhren strecken sich von den Siebrahmen aus. Geflanschte Verbindungen garantieren eine auslaufsichere Anbindung mit den Reinigungsmittelröhren.

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.

Das Kason Ballklopfsystem eignet sich besonders für Anwendungen, wo trockenes Material mit einer sehr genauen Granulometrie zu sieben ist. Eine Ballklopfstütze wird unter dem Siebgewebe angebracht. Die Vibration der Siebmaschine erregt die elastomeren Bälle, die ununterbrochen gegen die Unterseite des Siebgewebes prallen. Diese Aktivität verursacht eine Flexion im Siebgewebe, wobei Material mit einer sehr genauen Granulometrie entfernt wird, um die Gewebe sauber zu halten.

Die Ringe "Kleen Screen"T verhindern Siebverstopfung wo faserige, klebrige oder strähnige Materialien versiebt werden müssen. Die Verknüpfung von exakt berechnetenToleranzen im Innern der Siebmaschine und der Trägheitsvibration auf mehreren Ebenen erzeugt eine Scherungsaktion, die Faser schert und klebrige Materialien abkratzt. Die hohlen Ringe helfen, dass die Produkte sich über die ganze Oberfläche der Siebmaschine ausbreiten.

The patented Kasonic^® anti-blinding device allows sifting as fine as 25 microns(500 mesh) on any circular vibratory screener of 18 to 100" (2540 mm) diameter. It transmits ultrasonic frequencies(adjustable) to the screen, adjusting power automatically according to screen loads. It operates with standard screens, reducing cost, and is supported independent of screen, prolonging screen life.

Das automatische Schmiersystem versorgt die Motorlagerungen mit Schmierstoff für 6 bis 12 Monate zwischen Erneuerungen des Schmierstoffbehälters. Ein kontinuierlicher Schmierstoffdurchfluss spült den Laufring und entfernt abgenutzte Materialien und Schmierstoffe und Fremdkörper. Tote Zonen unbenutzter Schmierstoffe werden dabei minimiert. Als Option für Siebmaschinen in Dimensionen von 1220 mm und größer verfügbar. Das System kann in einr Stunde in alle Rundschwingsiebmaschinen nachträglich eingebaut werden.

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

Das Wischerblattsystem verhindert Siebverstopfung und erhöht Durchsatzleistungen, indem es das Überkorn und Agglomerat zermalmt. Die Vorrichtung ist unabhängig montiert und erlaubt deswegen die Regulierung der Wischerblatthöhe über die Oberfläche der Siebgewebe und die Geschwindigkeit zwischen 1 und 15 U/min. Gummiwischblätter oder Börste können an die Schwingarme montiert werden.

Das Kason vierärmige Wischblattsystem wird über die Siebgewebe installiert, um Siebverstopfungen durch Schlämme und dickflüssige Produkte, usw., zu verhindern. Das System besteht aus vier Radialarmen in Neopren, die die höhere Oberfläche der Siebgewebe abwischen und gründlich reinigen. Für schwer zu siebende Materialien ist das Zubehör in Sonderausführungen lieferbar. Das System wird durch die Trägheitsvibration der Kason Siebmaschine aktiviert.

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.

Die Staubschutzhaube erlaubt die Überprüfung der höheren Oberfläche der Siebgewebe, und die Beobachtung des Flussbildes und vereinfacht den Zugriff auf das Oberdeck.

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.
