If your product is thick enough, an ordinary mixer will struggle with it; our Sigma mixer is designed for exactly that. Its two blades turn toward each other at slightly different speeds (1:1.25), so the mass is pulled, folded, and squeezed against the chamber wall on every pass. This is why putty, adhesives, sealants, rubber compounds, ointments, and doughs all come out uniform.

The chamber of Sigma Mixer is made of SS 304, and an MS C-channel base with internal rib supports, so the machine stays steady under heavy loads. The SS blades are made with castings by the support of shafts running in heavy MS casting housings with SKF bearings and Teflon glands. A helical gearbox (Elecon or Bonfiglioli) and an ABB, Siemens, BB or CG motor drive the blades, in standard or flameproof. To unload, the whole vessel tilts hydraulically and empties.

The larger models add process features. The SM-200 and SM-500 come with an SS 304 heating/cooling jacket, internal blade cooling, and a PLC panel with Siemens HMI and temperature and pressure sensors. The SM-200 also has a hydraulic top cover with a locking system. The SM-1000 is built around a VFD and panel.
