z blade for Sigma mixer

Sigma Mixer Operation

Sigma mixer, the tangential action of mixing and kneading is thoroughly obtained by ‘Z’ (SIGMA) shaped kneading blades, which rotates very accurately at different speed towards each other causing product to be transferred from blade to blade. Discharge of the mixed product is achieved by tilting the container or through the valves at the bottom or by means of an extrusion screw below the container if provided

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.

Salient Features

  • Sigma Mixer is a Batch type Mixer
  • In sigma mixer, Mixing Trough and Blades are fabricated from mild steel, stainless steel 304 and 316 grade.
  • Blades of sigma mixers are designed to obtain thorough mixing of high viscosity materials.
  • Sigma Mixers Blades are machined to keep minimum equal gap between through walls and blades.
  • Sigma mixers have fixed with Heavy-duty gears to sustaion of load of Kneading.
  • Shaft sealing into the stuffing boxes is provided by Teflon Chevron Rings / PTFE breaded gland rope to prevent leaking from blade ends.
  • Safety Guards and Grills are provided for maximum safety in sigma mixers.

Lab Sigma Mixer- Z Blade

Uniform Kneading & Mixing Process

Application & Process :

The Abster Equipment LAB Series – Lab Scale Sigma Mixer is 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 Lab sigma kneader is a twin 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.


New Design Features :

  • For Mixing, Blending and kneading of high Viscosity Materials, with a combined action of Bulk Movement, Kneading, stretching folding, dividing and Recombining.
  • Available in Capacity from 1 Kg to 5 Kg Industrial Productions.
  • Designed as per cGMP – Current Good Manufacturing Practices & Non GMP STANDARD Model.
  • Contact parts in AISI 316, AISI 304 or MS as desired by customer.
  • There are different types of blades: Sigma-“Z” blade, Spiral blade, and Naben blade.
  • Selection of appropriate blade shape and speeds result in excellent mixing.
  • Safety feature : Over Load protection & Enclosed drive
  • Option for Hydraulic lifting unloading & spraying system.
