Sigma Mixer Specification

For Optimum Solutation of : Kneading, Dispersing & Mixing for High Viscous material

The Sigma Mixer / Sigma Kneader is a horizontal mixing machine with two Sigma, or Z-type blades. Two different gears drive the two blades, and one shaft is 1.5 times the speed of the other blade. It has one powerful motor and a speed reducer to drive the 2 blades. The Kneader reactor usually has a W-type barrel with a hydraulic tilt that turns it and a heating jacket outside.

APPLICATION:

Suitable for Kneading, Mixing & Dispersing and of viscous material having dough like consistency used in the Paint, Pigment, Chemical, Pharmaceutical, Food, Adhesives, Dyestuff, Paint, Refractory, Rubber, Plastic and related industries.

Tilting option:

Hydraulic tilting system is provided with complete power pack, electric motor, pressure valves, pipes, fittings, cylinders and hoses which makes the tilting mechanism quick, easy and simple to operate.

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, 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 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.

Standard Features

  • Available in all grades of Carbon Steel and Stainless Steel.

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.
