How it Works

Benefits of choosing a ROSS/AMK Kneader Extruder

What does a ROSS/AMK Kneader-Extruder do?

ROSS/AMK Kneader Extruders combine 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 exceeding 10 million cP. These machines are used throughout the chemical, pharmaceutical, plastic, coating, ink, paint, adhesive, composite, and food product industries in the manufacturing of highly viscus, thick and very sticky products such as silicone rubber, putties, printing ink, oxide ceramics, hard metals, and marzipan.

How does a ROSS/AMK Kneader Extruder work?

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 constantly feeds new materials into the mixing blades. After the mixing/kneading cycle is complete, the screw directions are reversed to extrude the finished product from the mix zone out through a discharge die and on to further processing or packaging.
