Sigma Blender
The sigma blender is a double arm mixer with the two “Z” or Sigmoid blades rotate towards each other at same or different speed inside a W- shaped product container and extruder screw is located between the two blades. The kneading blades run at different speeds. Because of their different speed, the blade sides approach and withdraw alternately. This causes twirling movement of the material which creates excellent dispersing and homogeneity. Each blade moves the material in opposite direction thereby providing excellent cross mixing of all raw materials. The blades pass the trough walls and each other at close clearances resulting in high pressure tensile and shearing rates and therefore heavy friction in the kneading medium and hence good mixing. The sigmoid shape of the kneading blades enables a steady flow of material from the walls to the center of the trough.

Working Principle
Loading of material is done through top of mixer on opening the lid or through the feeding mouth/hopper. On starting the machine, the tangential action of mixing and kneading is thoroughly obtained by Z (sigma) shaped kneading blades, which rotates very accurately at different speed towards each other causing product to be transferred from blade to blade. Discharge of the mixed product is achieved by tilting the container or through the valves at the bottom or by means of an extrusion screw below the container if provided.
Applications
