Co-rotating twin screw extruders

ZSE MAXX TWIN SCREW EXTRUDER SIGNIFICANTLY MORE THROUGHPUT THANKS TO: Pertinent benefits Leistritz is one of the worldwide leading manufacturers of twin screw extruders. It is only possible to offer a fully developed product range by means of constant innovations and an open ear for the requirements of the users. The ZSE MAXX series is the first series of extruders that offers an ideal combination of high torque and large volume in ONE machine. ↗ maXXvolume High, free volume in the screw (OD/ID = 1.66) This opens up a great degree of freedom for users: increased throughputs and a...

More throughput by means of increased volume More cooling capacity for a larger process window When running volume-restricted processes such as dryblends, pigment preparations, fillers or additive concentrates, the increased volume of the ZSE MAXX extruders can be fully used. With an OD/ID of 1.66, Leistritz has found the optimum ratio between high volume and effective energy input into the product. The shear effect in ZSE MAXX twin screw extruders allow an increased throughput of up to 50 % compared to predecessor models. This means that the energy balance in the processing unit changes...

More output for higher operating safety More splines for a better torque transmission Great demands are made on the gearbox of a twin screw extruder. With the relatively close axial distance of the two extruder screws, it has to transmit very high torque and counteract high backward pressure forces. Leistritz thus uses an extremely powerful drive concept for its twin screw extruders. The transmission gear with dual power distribution is a masterpiece of German engineering. The extremely high power densities were achieved by high-quality workmanship, constant research and long-standing...

Insulating the processing unit However, it is not only drive energy that is required to provide the energy needed for melting at low speeds. Energy also enters the process through the barrel heating. Leistritz offers insulations for processing units to reduce the heat-up times and to use the barrel heating even more efficiently. OPTIMUM ENERGY UTILIZATION New "solutions" The extrusion process is energy-intensive. In order to reduce energy costs, operators aim for both high throughputs and an optimum energy utilization. Leistritz can offer a number of solutions in this field. Optimum OD/ID...

MODULAR SCREW SYSTEM The heart of the extruder Leistritz offers a wide choice of screw geometries that can be combined in a large number of variations. Generally, there are conveying, kneading and mixing elements. The competence of the Leistritz process engineers enables them to create an optimum screw design for the respective application. Depending on the geometry, various screw elements are placed and fixed on the screw shaft which has a spline profile. KB (kneading block) ↗ Standard element in 30°, 60° and 90° design for melting, dispersing and incorporating fillers ↗ The most important...

MODULAR BARREL SYSTEM BARREL HEATING/COOLING Extensive portfolio Heating cartridges are used to heat up the barrel in the fastest and most effective way. They enable: ↗ Short heat-up times The processing unit must naturally also have a modular structure in accordance with the screw geometry. Leistritz offers barrels with various openings and inserts for material feeding, degassing and venting for the The optimum combination of cooling and heating is one of an extruder‘s essential quality characteristics. It plays a very important role so that every process can be adequately run. Each barrel...

ZSE MAXX SERIES System for maXXimum possibilities The very high specific torque (15 Nm/cm³) and the large volume (Da/Di = 1,66) in ONE extruder – this is what has distinguished the ZSE MAXX twin screw extruder in the market for over a decade. This enormous adaptability of the ZSE MAXX series provides the user with a processing advantage: A large range of processes can be covered with one ZSE MAXX twin screw extruder. Spec. torque density (Nm/cm³) up to max. » The ZSE MAXX series is the most elaborate twin screw extruder series with a consistent OD/ID and high torque, which facilitates a...
