APPLICATION

The 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. Such as Adhesives, Explosives,  Butyl rubber, Food and confectionery products, Moulding preparations, Soaps and detergents, Carbon pastes, Gaskets and Gland Packings, Pencil erasers, Solid propellants, Ceramics Grinding wheel preparations, Pharmaceuticals, Sugar pastes, Chemicals, Hot-Melts, Plastics, Viscous rubber solutions, Chewing gum, Inks and pigment products, Putties, Crayon and pencil lead, Marzipan, Refractories.

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:

• Low mixing time approx. 15% less time.
• Eliminates the manual task of scraping out sticky/tacky materials.
• Eliminates 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.

Advantages over conventional tilting bottom discharge kneaders:

• Low mixing time.
• Continuous operation possible because of extrusion screw.
• Elimination of the manual scraping of sticky/tacky materials.
• Eliminates operator exposure to materials at elevated temperatures or those of a toxic nature, thereby improving plant safety.

 

 

Advanced Double Shaft Sigma Kneader Technology

This kneader extruder utilizes a double shaft sigma kneader mechanism, offering thorough mixing and kneading of diverse materials. The design ensures optimal homogeneity and process efficiency, making it ideal for applications that demand consistent results. High torque and precise movements enable the handling of viscous and semi-solid materials effectively.


Customizable for Industrial Needs

Crafted from durable stainless steel, the Sigma Kneader Extruder withstands rigorous industrial usage. Its 100 kg batch capacity and 100 mm screw diameter are well-suited for medium to large-scale operations. Equipped with a PLC control system, operators benefit from customizable process parameters and enhanced safety during operation.
