Sigma Kneader Extruder

The SIGMA 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:
a cLow mixing time approx. 15% less time.
a cEliminates the manual task of scraping out sticky/tacky materials.
a cEliminates operator exposure to materials of elevated temperatures or of a toxic nature, thereby improving plant safety.

Many Different sizes and designs are available to meet the most stringent process needs. Kneader Extruders are manufactured in many sizes from 5 through 2500 Liters capacity. Other sizes manufactured on request.
