A Futura II combined de-air ing extrusion unit comprising an MDVG 920f

de-airing double-shaft mixer and a Futura II E 56a/50 extruder

HNDLE offers a complete line of combined de-airing

extrusion units for a broad range of applications.

Our units are of modular design, comprising extruders

and de-airing mixers of various size. In designing the

Futura II extruder, HNDLE systematically implemented

the latest in mechanical- and process-engineering know-

how pertinent to extrusion technology and the resultant

products boast accordingly favorable price-performance

ratios and customer-benefit orientation.

Futura II is available with barrel diameters of 200 to

750 mm, maximum extrusion pressures ranging from 20

to 50 bar and volumetric throughputs of 1.9 to 60 m/h.

Modularized extruder

Load- and function-appropriately engineered crucial

components, e.g., gearing, coupling, thrust bearing,barrel and auger, all as part of an overall modular

concept.

Modularity

We incorporate the latest products of modern control

technology and motive-power engineering. Continuous

operating-data acquisition, energy conservation,

equipment monitoring and protection, plus defined

control response set new standards and blaze new trails

for future shaping systems by HNDLE.

Large dimensioned gears, maximized mechanical

efficiency and easy installation + removal these are the

crucial characteristics of the gearing technology that

HNDLE and its partners have developed for their new-

generation extruders.

The modularity of the drive assembly with separate

paddle drives yields a combination of easy maintenance

and lower energy consumption.

Separate paddle drives

In any extruder used for producing thin-walled holloware

or tiles, dry particles and sizable surface-dry agglo-

merations are bound to increase the rejects rate.

HNDLE, though, applies special coatings as a

standard feature, effectively preventing material buildup

and, hence, dry agglomerations.

Extruder body

HNDLE's threadless wear-part fixation technique yields

unparalleled "vacuum tightness" for the en-tire system

plus quick & easy maintenance.

No dry particles, no false-air infiltration and no

vacuum-related lamination

Threadless wear-part fixation

The geometry of all augers, including the front-end

auger, is always in balance with product and compound,

hence guaranteeing flawless homogenization, plastifi-

cation and de-airing in combination with high throughput.

Optimal auger geometry

Design

Diverse wear-prevention concepts all tailored to the

respective product performance specification

No matter what the load, the auger remains perfectly

centered on the shaft thanks to its triangular polygon.

This arrangement guarantees symmetrical power flow

into the shaft. The self-centering Hirth coupling ensures

optimal positioning of the front-end auger with respect to

the rear-end auger (at 7 increments).

Fewer extrusion textures produced, and ideal

shaping conditions in pressure head and die thanks

to uniform advance of the clay column out of the front

auger.

Barrel, auger and body can all accommodate supple-

mentary pairs of counter knives.

Depending on the extrusion compound, the envisaged

product and the targeted throughput rate, made-to-

measure solutions are possible. Very sticky clay, for

example, can be adequately de-aired and readied for

untextured extrusion.

Variable combinable augers andcounter knives

A de-airing mixer upstream of the extruder serves as a

connecting component between body prepara-tion and

the actual shaping process. Together, they form a multi-

functional system for attending to the material's mixing,

kneading, shredding, de-airing, wetting, steam-heating,

etc. The homogeneity of the body, as a prerequisite for

good shaping, is decisively determined by the de-airing

mixer.

Function

Some 2/3 of the overall homogenization achieved in ade-airing double-shaft mixer takes place in the closed

compression section. High pressure in the compression

zone is essential to excellent vacuum, just as infinitely

adjustable mixing paddles are essential for perfect

mixing. The more homogeneous the compound, the

better (and more economical) the extrusion.

A large-volume de-air ing chamber facili tates main-tenance and helps achieve better vacuum conditions.

HNDLE has put all these scientific insights into practice

by extending the compression zones of our de-airing

double-shaft mixers and enlarging the volume of their

de-airing chambers.

specific situation.

energy-saving feeding of the "open auger" in the

Possible combinations

Our extruders combine with horizontal de-airing double-

shaft mixers and vertical primary pug mills. The following

table illustrates the most commonly employed combina-

tions.

Vertical single-shaft mixers are unbeatable for feeding

tile, facade-element and panel extruders.

Maximum accessibility, simple cleaning and state-of-

the-art drive mechanisms as these machines'

distinguishing features.
