This 2000L electric heating sigma mixer is designed for heavy-duty mixing and kneading of high-viscosity materials. The machine is equipped with screw discharge, ensuring efficient and clean material output. With thermal oil circulation in the mixing blades, discharge screw, and external jacket, it provides precise temperature control for processing sensitive formulations.
It is widely used in the waterproof materials industry, adhesives, sealants, rubber compounds, and other applications that require controlled heating during mixing.

| Feature | Screw Extrusion Discharge (This Model) | Tilting Discharge |
|---|---|---|
| Efficiency | Continuous and controlled output, especially for sticky or viscous materials | Batch discharge, may leave residues |
| Material Flow | Smooth extrusion through screw barrel | Relies on gravity, less control |
| Space Requirement | Compact design, no need for tilting clearance | Requires larger working area for tank rotation |
| Operator Effort | Easier operation, minimal manual handling | Requires more manual operation |
| Best for | High-viscosity materials like silicone rubber, adhesives | Medium-viscosity materials, easier to flow |
