Sigma Mixer Extruder – The most common device employed in high viscosity processes is the sigma blade mixer with extruder for discharge. A sigma blade mixer extruder is composed of two z-shaped blades mounted on a horizontal trough. The blades run toward each other at different speeds and in a bottom cavity, a mixing screw rotates in reversible directions, either feeding materials to the sigma blades during the mixing cycle or extruding the finished product during discharge.


Z Blade Sigma mixer extruders are used in a wide range of industries and applications including:

Gum bases, Sugar pastes, Adhesives, Polymers, Hydrocolloids, Sealants, Mastics, Soaps, Detergents, Silicone rubbers, Energetics, Brake linings, Confectionery, Waste recycling, Rubber solutions, Fibreglass doughs, Ceramics, Roof tiles.

How the Sigma Mixer Extruder Works

Our Sigma mixer 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
