Sigma blade mixer

bottom-entrybatchsolid/liquid

Product overview
The Sigma-type industrial kneader with 3000 L capacity is engineered for mixing, kneading, dispersing and repolymerizing high‑viscosity elastic‑plastic materials. It provides uniform mixing through differential‑speed paddle rotation and is available in vacuum, pressure and atmospheric configurations.

Equipment introduction

• Mixing system: two groups of paddles (Σ‑type or Z‑type) rotating at different speeds to generate strong extrusion and shear for homogeneous mixing.
• Configurations: vacuum type, pressure type, atmospheric (normal pressure) type.
• Temperature control: heat transfer oil, jacket electric heating, steam heating, water cooling options.
• Opening mechanism: hydraulic opening for the mixing chamber.
• Discharge options: hydraulic cylinder dumping, bottom discharge, screw extrusion.

Advantages

• Uniform dispersion and high kneading efficiency for pastes, sealants, silicones, adhesives, resins and pigments.
• Customisable line integration: suitable for single units or complete production lines with plant‑specific adaptations.
• Short engineering lead times: typical drawing delivery ~3 days; typical shipment ~1 month depending on specification.
• After‑sales: one‑to‑one pre‑sale consultation, production reporting (photo/video), nationwide support, 1‑year warranty and lifetime maintenance options.

Applications

• High‑viscosity sealants and adhesives, silicone rubber, BMC, battery materials, inks, pigments, dyes, pharmaceuticals, resins, plastics, rubber, cosmetics and related formulations requiring intensive kneading and dispersion.

Company advantages (summary)

• Delivery of complete production line design and equipment supply.
• Experienced technical team with long‑term focus on chemical processing equipment.
