COMBINED DE-AIRING EXTRUSION MACHINES FUTURA II PZG/ E PRODUCT INFORMATION The experience gleaned from the supply of over 5000 auger extruders and our systema- tic approach to the practical implementation of cutting-edge scientific insight are our main strengths. Not for naught are we a lea- der in extrusion technology.

PRODUCT INFORMATION PZG E TOP-NOTCH EXTRUSION HNDLE offers a complete line of combined de-airing extrusion machines for a broad range of applications. Our units are of modular design, comprising extruders and de-airing mixers of various

size. In designing our Futura II extruder, HNDLE 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.

CRUCIAL CHARACTERISTICS OF FUTURA II IN BRIEF: Maximum throughput thanks to optimized filling of the de-airing chamber Superior durability thanks to robust construction and minimized wear Low energy consumption coupled with permanent operating-data acquisition Easy maintenance thanks to

large de-airing chambers with accordingly superior vacuum condition Guaranteed uniform column advance thanks to optimized auger geometry

PRODUCT INFORMATION PZG CRUCIAL CHARACTERISTICS OF THE FUTURA II SERIES: Modular design State-of-the-art motive engineering Load- and function-appropriately engineered crucial components, e.g., gearing, coupling, thrust bearing, barrel and auger, all as part of an overall modular concept. 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 are our main selling points and they're all to your benefit. Modular design of the extruder HNDLE combined de-airing extrusion machine Futura II type E 65a/ 65/ MDVG 1025f

Robust gearing Separate paddle drives Harmonization of the auger-shaft and paddle-shaft speeds as part of the modular approach guarantees optimal filling of the vacuum chamber and, hence, maximum throughput extrusion with extensive freedom from lamination, highest delivery number, reduced energy consumption and minimal

friction-induced temperature rise. Oversized gears, maximized mechanical efficiency and easy installation + removal - these are the crucial characteristics of the gearing technology that Hndle and its partners have developed for their new-generation extruders. The upshot of all the effort: long service life with little maintenance and maximum loading capacity! High-tech gearing with separate paddle drives Threadless wear-part fixation With clamped barrel shell Hndle's threadless wear-part fixation tech- nique, for which a patent is pending, yields unparalleled

"vacuum-tightness" for the entire system - plus quick & easy maintenance. Your benefit: no dry particles, no false-air infiltration and no vacuum-related lamination. Optimal auger geometry The geometry of all augers, including the front-end auger, is always in balance with product and compound, hence guaranteeing flawless homogenization, plastification and de-airing in combination with high throughput.

PRODUCT INFORMATION PZG Cast paddles - especially good for frequent changes of body Cooling of barrel and body In any extruder used for producing thin-walled holloware or tiles,

dry particles and sizeable surface-dry nodules are bound to increase the rejects rate. Hndle, though, has engineered new solutions for the FUTURA II series that provide condensation surfaces, remoisten the compound and preclude both changes in plasticity that detract from quality and unsufficient vacuum at elevated temperatures. The additional measures we have taken to rule out dry nodules in vacuum extruders include special coatings for the vacuum chamber and extruder body. Self-centering augers and Hirth coupling 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 (7 in-crements). A new way of mounting the double- or triple-flight front-end auger on the shaft enables use of an extremely slender hub: fewer "S cracks" are reduced, and uniform advance of the clay column out of the front-auger creates ideal shaping conditions in pressure head and die. Hirth coupling

Some 2/3 of the overall homogenization

achieved in a de-airing double-shaft mixer takes place in the closed compres- sion section. High pressure in the compression zone is essential to excellent vacuum, just as infinitely adjustable mixing paddles are essential to perfect mixing. The more homogeneous the compound, the better (and more economical) the extrusion. A large-volume de-airing chamber facilitates maintenance and helps achieve better vacuum conditions. HNDLE 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. Flexibly combinable augers and spiders Built-in pair of spiders and triangular auger shaft Barrel, auger and body all accommodate spiders or pairs of spiders at any point. Depending on the extrusion compound, the envisaged product and the targeted through- put rate, made-to-measure solutions are possible. Very sticky clay, for example, can be adequately de-aired and readied for untextu- red extrusion.

In any case, though, separately driven paddles guarantee optimal, energy-wise feeding of the "open auger" in the de-airing chamber - no matter what the configuration.

THE RIGHT VACUUM EXTRUDER FOR THE RIGHT PRODUCT: POSSIBLE COMBINATIONS Our extruders combine with horizontal de-airing double-shaft mixers, horizontal single-shaft mixers and vertical de-airing single-shaft mixers. Table 2 surveys the most commonly employed combinations: Vertical single-shaft mixers by HNDLE are unbeatable for feeding tile and slug presses Maximum accessibility, simple cleaning and state-of-the-art drive mechanisms distinguish these machines EXTRUDER TYPE MS 40a MS 50a PZHVG 25c MDVG 715d MDVG 912b MDVG 920f MDVG 1025f MDVG 1220b PZG 25 PZG 35 PZG 40 E 56 E 65 E 75
