Sigma Blade Mixer

A sigma blade mixer (or Z-blade/kneader mixer) is a heavy-duty batch mixer for highly viscous, pasty, or solid-liquid materials, featuring two intermeshing, sigma-shaped (or Z-shaped) blades that rotate in opposite directions at different speeds within a W-shaped trough, creating intense shearing, kneading, and folding action for uniform mixing in a figure-eight pattern. Used across industries like chemicals, food, pharma (for ointments/dough), paints, and adhesives, they handle materials up to very high viscosities and often feature jacketed vessels for temperature control. 

• Blades: Two “Z” or sigma-shaped blades that run at different speeds to thoroughly mix materials.
• Mixing Action: The blades pull, shear, compress, and fold the material against the trough walls, ensuring complete homogenization.
• Viscosity: Designed for high-viscosity products (e.g., dough, pastes, putties, rubber compounds).
• Trough: A W-shaped trough accommodates the blades; often jacketed for heating/cooling.
• Discharge: Material is discharged via tilting, a bottom valve, or an extruder screw.
• Applications: Ideal for pharmaceuticals (tablet masses), food (dough), inks, paints, adhesives, sealants, and rubber. 

• Chemicals: Resins, polymers, dyes, pigments, adhesives, sealants.
• Food: Doughs, confectionery, thick pastes.
• Pharmaceuticals: Tablet masses, ointments, stiff pastes.
• Cosmetics: Creams, pastes.
• Rubber & Plastics: Rubber compounds, PVC coatings, putties.
• Sigma mixer capacities vary widely, from small lab models (e.g., 10-20 Liters) to large industrial units (up to 5,000-10,000 Liters or 50-2000+ kg/batch), designed for viscous, sticky materials like dough, pastes, and heavy compounds, with specific sizes depending on the application (food, pharma, rubber) and manufacturer.
  Typical Capacity Ranges:

  Lab/Pilot Scale: 10 Liters to a few hundred Liters (e.g., 10L, 50L, 150L).
  Production Scale: Hundreds to thousands of Liters (e.g., 500L, 1000L, 2000L, 3000L).
  Heavy Duty/Industrial: Can reach 5,000 Liters or more, often measured in kilograms per batch (e.g., 500kg, 1000kg, 2000kg).

  Factors Influencing Capacity:

  Material Viscosity: Higher viscosity materials (like dough) require larger working volumes relative to the total bowl size.
  Application: Food-grade mixers might focus on volume, while industrial ones handle heavier loads (kg).
  Manufacturer: Different brands offer different standard models (e.g., 1000L, 2000L, 3000L).
