Sigma Mixer (Sigma Blade Mixer / Kneader)
A Sigma Mixer is a heavy-duty industrial machine designed for mixing, kneading, and homogenizing high-viscosity materials. It utilizes two sigma-shaped (Z-shaped) blades that rotate in opposite directions to create intense shear and kneading forces, effectively blending and folding thick, sticky, or viscous substances.
Key Details:
Category: Industrial High-Viscosity Mixer / Kneader
Chemical Formula: N/A (Machine / Device)
Construction: Typically made from stainless steel or carbon steel,
often with jacketed vessels for heating/cooling and hydraulic tilting
for discharge.
Description:
- Trough or container is W-shaped, double-U, or rectangular, housing two sigma-shaped (Z-shaped) blades.
- Blades rotate in opposite directions at variable speeds (commonly 3:2 ratio), producing shear, compression, and kneading forces to mix materials thoroughly.
- Optional vacuum capability removes trapped air; suitable for very thick or sticky materials up to 10 million centipoise.
Common Uses / Applications:
- Chemicals: Adhesives, sealants, silicones, paints, dyes, putties, resins.
- Food Industry: Chewing gum, chocolate, dough, confectionery pastes, candy.
- Pharmaceuticals: Ointments, pastes, creams, granulated tablet powders.
- Plastics / Rubber: Compounding, masticating rubber, mixing polymer additives.
- Other Industries: Pencil lead, ceramics, magnetic tape coatings, battery pastes.
Advantages:
- Uniform Mixing: Achieves up to 99% homogeneity in high-viscosity materials.
- Robust Design: Capable of handling heavy loads and high shear.
- Customizable: Available with various discharge mechanisms, including tilting or extrusion screws.
