Leading Manufacturer, Supplier & Retailer of Sigma Mixer Extruder.

Sigma Mixer Extruder

Excellent for kneading and mixing of highly viscous materials like dough, putty, rubber solutions, adhesives, polymers etc. The mixing action is a combination of smearing, stretching, folding, dividing and recombining as the material is processed between the sigma blades and the container walls. Jacket arrangement is provided for heating or cooling application. In bigger models the container is tilted by a hydraulic cylinder to ensure complete discharge of mass.

**Note The actual power consumption shall depend upon the application and the properties of the material to be mixed (Density, Viscosity etc.)** Note As improvements in design are being made continuously, the above specifications should be considered for reference only. The equipment built may differ due to our policy of continues product development.

Note : Working capacity to be calculated @ 60% of Total Capacity.

Description
Sigma Mixer Extruder

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.

Sigma Mixer

ABF introduces the modern and heavy duty, strong built Sigma mixer (kneader) to produce uniform mixing and kneading heavier viscosity materials. The Sigma mixture is suitable for many applications like mixing, kneading, Grinding, dispersion, drying etc. The sigma mixer have application to produce highly viscous materials like different kinds of Chemical, Dyes & Pigments, Paint, Polymers Plastic, Putties, Plastic, Pharmaceuticals, Printing ink, stiff pastes, adhesives, polyester Compounds, flush colors, brake lining compounds, resign, soap, PVC coatings, Rubber compounds, Confectionery, Magnetic Tape Coatings, Ceramic, Carbon Black, doughs, , Food Products, Fiber Glass, Grease, Lead Storage Battery, Soap & Detergent etc.

Sigma Mixer Options
  • GMP / Non GMP / models.
  • Discharge in sigma mixers is done by tilting container / bottom sliding valves / bottom gates / flush bottom gate valves.
  • Tilting in sigma mixers is done by hand liver / hand wheel with lead screw / electrical arrangements / hydraulic systems.
  • Lifting of lead either manually, with help of counter weights or hydraulically.
  • 'Z' Type Spiral blade / Naben / double naben blades to circulate hot / cold water in cases of heavy masses.
  • Jacketed shell for heating or cooling by steam, oil, water etc. with fiber glass insulation over the jacket.
  • Spray system for liquid addition / gas purge.
  • Flame proof / Non-flame proof electrical controls.

Sigma Dough Mixer

TheSigma Mixeris used for mixing and kneading for mixing, kneading of highly viscous mass, sticky and dough like products, Mixing of pastes, rubber, and heavy plastic masses, applications in Food, Rubber, Pharmaceutical, Chemical and agro industries, Dry powder to wet phase mixing. This mixer is most suitable for highly viscous material and dough like masses.

The sigma Sigma is a double arm mixer, the two "Z" blade rotate towards each others at same or different speed inside a W- shaped product container. The twin screw basin kneading machine with two horizontally arranged kneading blades, which are deeply geared into one another and strip themselves reciprocally. Each blade moves the material in opposite direction thereby providing excellent cross mixing of all raw materials. The blades pass the trough walls and each other at close clearances resulting in good mixing. The close clearance produces a shearing and tearing action that is beneficial to the size reduction of solids. Selection of appropriate blade shape and speeds result in excellent mixing

Sigma Dough Mixer Adavntacges
  • Two mixing blades placed in a 'w' shaped horizontal trough
  • Commonly used blade types are the sigma blade, masticator blade, spiral blade, shredder and naben blade
  • Rotation of the blades is either tangential to each other or the blades may overlap within the trough.
  • Blades pass the container walls and each other at close clearances generally (1-2 mm)
  • The mixer bowl may be jacketed for circulation of heating or cooling media.
  • Viscosity range upto 10 million cps
  • Viscous mass of material is pulled, sheared, compressed, kneaded and folded by the action of the blades against the walls of the mixer trough.
  • Fill Up is 40 65 % of bowl volume
  • Mixing homogeneity upto 99 percent
  • Specific power 45 to 75 kW/ m3
  • Discharge of the material from the mixer By tilting of the mixer container
  • Bottom discharge valve Through an extruder, screw
