Sigma Mixer Blade Types

Manufacturer of Sigma Mixtruder in Mumbai IndiaTangential design Sigma Blade

The rotation of the Double Arm Mixer blades is either tangential to each other or overlapping. ‚Äč

Tangential design: The blades in tangential design rotate in the trough meeting tangentially. The front blade generally rotates faster than the rear blade, usually in the ratio of 3:2. Tangential blades are used for universal applications such as adhesives, rubber compounds, flush colors, dyes, and pigments.

Overlapping design: In the overlapping design, the blades overlap above the saddle of the chamber. The relative position of the two blades is fixed, and the rotation speed is the same for the two blades.

Materials that flow freely are mixed using the overlapping blade action, such as carbon pastes, clay coating, creams, and ointments. This design offers a faster interchange of material from one compartment to the other. The overlapping blade produces a lower kneading and shearing compared to the tangential blade action.
