How the Kneader Extruder Works
Our Kneader Extruder combines the efficiency of a double arm - sigma blade mixer with the convenience of an extrusion screw for the mixing and discharging of heavy viscous materials.
The Kneader Extruder includes a set of counter-rotating kneading blades and a discharge screw. The blades are mounted on a horizontal axis in a u-shaped trough. Below the blades in a separate cavity is the discharge screw. During the mixing cycle the blades rotate toward each other while the mixing screw rotates in a reverse direction, constantly feeding new materials into the mixing blades. After the mixing/kneading cycle is complete, the screw is reversed and it transports the mixed materials from the mix zone out through a discharge die and on to further processing or packaging.
The Kneader Extruder has several advantages over conventional non-screw discharge kneaders:
1. Mixes in approx. 15% less time
2. Eliminates the manual task of scraping out sticky/tacky materials.
3.Eliminates operator exposure to materials of elevated temperatures or of a toxic nature, thereby improving plant safety.
Many sizes and designs are available to meet the most stringent process needs. Kneader Extruders are manufactured in many sizes from 1 through 1000 gallons capacity.

The Sigma or "Z" Blade is the most popular and universal blade design used with Kneaders. This blade provides good horizontal transfer of all materials in the mixing trough.
The Knobben blade is used for the mastication of highly viscous masses that contain large blocks of polymers.
Banbury Blades are primarly used in conjunction with ram covers. The ram cover/banbury blade combination provides the maximum possible shear rates to the mixture.
The cutter blade mounted at the discharge helps to pelletize materials during discharge.
A round hole die is available in many shapes and sizes. This enables a user to discharge into a particular shape for further processing or packaging.
The largest opening possible is restricted only by the diameter of the discharge screw. This die allows the fastest disarge rates of all the dies that are available.
Replacable wear resistant blade tips are available
for use in special applications that include highly abrasive materials such as abrasives for grinding wheels.
Trough saddles can be supplied as a replaceable component. If the mixer is going to be used to mix abrasive materials, this option hould be considered as the saddles are the highest wear section of the trough.
The entire trough can be lined with abrasion resistant materials.
