sigma mixer/Z blades mixer/kneading machine/sigma kneader with double Z/Sigma Blades, is to be used for mixing and kneading of low-to high-viscosity products in many industries such as BMC/DMC, Chewing gum, candy/sugar paste, plasticize/silly putty, Hot melt adhesive , silicon compound, CMC/Cellulose, Electrode paste, carbon, pencil leads, soap, pigments, inks, plastic ect.

Machine structure:

Including kneading/mixing system, machine base, hydraulic system, transmission system, electric control system, heating system (optional), cooling system (optional), vacuum system (optional) —- Discharge: Tilting discharging Screw extruding discharging Ball valve/bottom plate ( manual, electrical, pneumatic) Tips: for BMC/DMC Application, normally discharging by tilting or screw extruding, actually tilting discharge is quite common in BMC/DMC. —- Heating: electric heating, hot water heating, hot oil heating, steam heating Tips: for BMC/DMC Application, heating is not required. — Cooling: Z blades water cooling, mixing chamber with jacket for cooling purpose. Tips: for BMC/DMC Application, cooling is not required. —- Vacuum system: water-ring vacuum pump and buffer tank.

Tips: for BMC/DMC Application, vacuum is not required.

The 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. Such as Adhesives, Explosives, Mastics, Sealing compounds, Biscuit dough’s, Fiberglass resin dough’s, Metal powders, Silicone rubber, Butyl rubber, Food and confectionery products, Moulding preparations, Soaps and detergents, Carbon pastes, Gaskets and Gland Packing’s, 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 Sigma Mixer 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 Sigma 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. Sigma Kneader Extruders are manufactured in many sizes from 5 through 2500 Liters capacity. Other sizes manufactured on request.

Standard Features
  • Available in all grades of Carbon Steel and Stainless Steel.
  • Available with single and twin screw designs.
  • Optional wear resistant liner plates provided for abrasive products.
  • Optional wear resistant liner plates provided for abrasive products.
  • Jacketed construction available for heating and cooling applications.
  • Can be offered for vacuum application.
  • Available in working capacities of 5 Liters to 2500 Liters. 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.
