Sigma Blender The tangential action of mixing and kneading is thoroughly obtained by two ‘Z’ shaped kneading blades, which rotates very accurately at different speed towards each other causing the product to be transferred from one blade to the other.
The mixing action is a combination of bulk movement, stretching, folding, dividing, and recombining of the material. The shearing & tearing action of the material against blades and the side walls causes size reduction of the solids. After the time period required for sterilizing the batch has elapsed, the heating circuit shuts of the pneumatic damper (exhaust) opens and cooling operation commences.

In the tangential design, the blades 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 generally used for material of higher viscosity such as adhesives, rubber compounds, flush colors, dyes, and pigments.
Sigma Blender In the overlapping design, the blades overlap above the saddle of the container. Due to the overlapping action it is necessary that the relative position of the two blades is unchanged, and as a result, both the blades rotate at the same speed. Materials that flow freely or creep down into the blades are mixed using the overlapping blade action. This design offers a faster interchange of material from one blade compartment of the mixer to the other. Overlapping Sigma blade action is used for materials of lighter viscosity such as carbon pastes, clay coating, creams, and ointments. The overlapping blade produces a lower kneading and shearing compared to the tangential blade action used in sigma mixer machine.
