Technical data Specialized machinery for special tasks: 12 sizes with particular benefits AUSKLAPPER AUßEN Six of the 12 ZE machine sizes – the ZE 25 UTX up to the ZE 75 UTX – are designed as UTX models. This design concept is distinguished by its particularly compact layout and the very high degree of operator friendliness and ease of maintenance. The ZE UTX laboratory and small batch extruder is available in A and R versions as well as in an A/R combination and in Ultra Glide version. The Ultra Glide has a drive unit, which enables the whole extruder drive unit with both screws to be...

AUSKLAPPER INNEN 2 Barrel cooling and heating

Technology made transparent First encounter: take a closer look at the ZE UTX twin-screw extruder 1 Drive train Our ZE extruders are characterized by above-average torque obtained by a special power branching system in the gear unit. Application of the latest in modern gearing technology has resulted in a very compact design and extremely low noise levels. A combined dip and pressure lubrication system protects the bearings and gears. If an overload occurs, a safety coupling instantaneously separates the drive from the extruder. 6 C-clamp barrel connectors W ith the C-clamp connectors,...

2 Barrel cooling and heating B arrel elements with a new type of heating and cooling system provide direct and intensive heat transfer and/or cooling. This allows the process in the extruder to be optimized by precise temperature control and dynamic control mode. Heating is done by high-power heating cartridges, which work faster and thus give more rapid start-up. The optimized layout and arrangement of the cooling bores provide high-efficiency counter-flow cooling with standard injection of high-pressure water or steam. 4 Side-feeders T he enlarged twin-screw side-feeder unit gives...

ZE twin-screw extruders Process implementation with utmost precision Process implementation with utmost precision The most precise way to run your process. Two concepts – one basis: 12 sizes each in two versions 24 extruder types in ZE-UTX/UT version 24 twin-screw extruders in two versions with 12 sizes each are available for performing the process steps involved in the manufacture of your products – efficiently and technically optimized. Both KraussMaffei Berstorff ZE-A and ZE-R extruder ranges present the same screw shaft center distance, making screws and barrels interchangeable when...

ZE-A version The ZE-A range, with an outer/inner screw diameter ratio of D/d = 1.46, offers an optimal relationship between free volume and torque, high screw torque and the highest throughput capacity. The ZE-A is thus especially suitable for high-performance compounding, alloying, filling and reinforcing, masterbatch production and the processing of powders or small-particle polymers. ZE-R version The ZE-R version has a big free volume. It features high residence times, high free volume with high torque, optimal melt surface renewal, low gas velocities and minimal shear energy input. Its...

ZE twin-screw extruders Perfect fine-tuning for any application Perfect fine-tuning for any application Do you know a more flexible building block system? Two barrel section lengths for each screw diameter. Barrel sections and screw elements are designed in strict accordance with the building block principle. With various types and different specifications that can all be combined with great versatility, there is virtually no limit to the barrel and screw configurations, which can be employed to meet your process requirements in the finest detail. The patented hardening method (DE 101 122...

In the case of twin-screw extruders of the ZE UT series, wear protection for machine sizes ZE90 UT and larger is accomplished by using solid nitriding steel barrels, barrels with through-hardened CrMo liners or barrels made of composite materials. The selection of the type of wear protection depends on the application the extruder is used for and on the specific conditions of wear. Barrel sections with an L/D ratio of 4 or 6 are available for the configuration of the modular processing section. These barrel sections are designed as – pen barrels for feed zones, o – pen barrels equipped with...
