Sigma Kneader

MIKRONS sigma kneader is a twin basin kneading machine with two horizontally arranged kneading blades, which are deeply geared into one another and strip themselves reciprocally. The kneading blades run to a ratio 1:2 Because of their different speed, the blade sides approach and withdraw alternately. This causes high pressure tensile and shearing rates and therefore heavy friction in the kneading medium, which creates excellent dispersing and homogeneity. The shape of the kneading blades enables a steady flow of material from the side walls of the kneading trough to the middle of the kneading trough.
Design Highlights
The two Z arm mixing blades rotate towards each other at differential speed inside a W-shaped trough
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 good mixing. The close clearance produces a shearing and tearing action that is beneficial to the size reduction of solids.
This mixer is most suitable for highly viscous material and dough like masses.
Selection of appropriate blade shape and speeds result in excellent mixing.
On completion of the mix cycle, the trough of the mixer is tilted and the product is discharged.
The mixer is also available with a bottom opening design for discharge
Wide range of blade types to choose from
