Screw Elements

CONVEYING ELEMENT, THREE-LOBED

The three-tobed conveying element not commonly sised in cow axtrusion lines. The screw siement Foo a divergens ratio of outside dameter to core Damen.A three-lobed conveying element is a mechanical component commonly used in positive.

REVERSE ELEMENT

Screw elements with reverse pitch direction are used to generate how restrictions in the melting or mixing zones. They normally have a length of half the outside diameter. NOTE also available in custom forms (refer to HPE element “single Piece element” on this).

CONVEYING ELEMENT, BI-LOBED

Bi-lobed conveying elements are used in current twin screw extrudes as standard element for feeding solids. Additionally they melt when pressure is build up before how restricted zones & the discharge. The volume conveying capacity .

CONVEYING ELEMENT, BIO-LOBED WITH HIGH SCREW PITCH

Tightly intermeshing conveying ele- ments with large pitch are used to pull in and convey also adhering materials. The pitch can be optimised to maximum conveying rate, where the optimum typically line between 1.3 and 2-times the diameter.

CONVEYING ELEMENT, SINGLE-LOBE

Single-lobe conveying elements. because of the wide tip, exhibit a better forced feeding behavior com- pared to two-lobed elements. These elements build up pressure with less energy input & often exercise a sealing-fuction toward the gearbox at the beginning of the screw.

TRANSITION ELEMENT, SINGLE-LOBED TO BI-LOBED

These transtion pieces of the type $12 create a transition between single and two-lobed sealing problem elements without dead spots”. They are needed in pairs since the elements for the left and right shaft much be dimensioned directly.

CONVEYING ELEMENT SE YY

Conveying element with single-lobe design where YY represents the tip width preferably reduced to the width of the bilobed screws. Is usually emp- loyed for relative large pitches in zones where much free conveying volume is required, that is, in the intake area or the area of sidefeeders and degassing openings.

TRANSITION ELEMENT, SE12

These transaction pieces create a conti- nuous transaction between single-lobe elements of the type SEA YY to two- lobed sealing problem elements without dead spots in which product may become deposited. The Transition Element SE12 is typically used in twin-screw extruders to facilitate the smooth changeover .

CONVEYING ELEMENT SKK

Two-lobed conveying element with two- sided pushing height at relatively large. pitch. This creates a large free conve- ying volume at simultaneously quite favourable blank angles. These elem- ents can also pull in large volume particles with low density.The Conveying Element SKK is designed for efficient material transport.

PUSHING FLIGHT ELELMENT, BI-LOBED

Conveying elements in bi-lobed design of the type SK with relatively large pitch where the active, that is the pushing hight features a pushing adge. These elements exhibit a relatively large free volume where the passive hights are cleaned by the nei- bouring elements. The fitting transation pieces have the designation SKN.
