Gear Mixer – Type ZME

The SME Screw Mixing Element features a bi-lobed screw profile with reverse-conveying milled recesses in a gear-type configuration. It provides gentle yet effective distributive mixing and is especially suitable for materials that do not tend to form deposits inside the extruder.

Screw Mixing Element – SME

Gear Mixer Block – Type ZB

The ZB Gear Mixer Block is constructed using alternating gear rims on the left and right shafts, offering high flexibility in dimensions and configurations. The teeth can be designed for forward or neutral conveying, delivering efficient mixing across a wide range of extrusion applications.

IGEL Mixing Element

The IGEL Element is formed by overlapping right-handed and left-handed screw cuts, creating diamond-shaped spikes for intensive distributive mixing. With neutral conveying behavior, this element is ideal for achieving uniform dispersion without influencing material transport.

Eccentric Netural Transition Kneading Block – KBX

Neutral Kneading Block

The Neutral Kneading Block is a standard bi-lobed kneading element with tightly intermeshing discs arranged at a 90-degree offset. Its conveying-neutral design allows precise control over material flow and residence time, making it suitable for balanced mixing applications.

Shoulder Kneading Block – KBS

The KBS Shoulder Kneading Block is engineered to reduce shear peaks by utilizing narrower discs and wider overflow areas. This design promotes smoother, more homogeneous melting and has proven effective as a standard kneading solution in demanding extrusion processes.

Reverse Kneading Block

Reverse Kneading Blocks are designed to build pressure and create material backup within the extruder. They enable high energy input for intensive mixing while being carefully dimensioned to prevent excessive shear stress and pressure peaks in sensitive materials.

Conveying Kneading Block

The Conveying Kneading Block combines kneading action with controlled conveying capability. Available in various disc widths and offset angles, it supports partial material transport while maintaining effective mixing, making it ideal for balanced processing zones.

Eccentric Transition Kneading Block – KBX

The KBX Eccentric Transition Kneading Block is used in dispersion and melting zones to deliver high energy input and superior melting performance. Its specialized eccentric geometry ensures efficient material treatment under high-power extrusion conditions.

High-Performance Eccentric Kneading Block

Designed for modern high-torque extruders, this eccentric kneading block offers exceptional melting capacity through optimized geometry and controlled energy input. It is ideal for high-performance extrusion systems requiring efficient dispersion and thermal stability.
