In the chemical, polymer and engineering materials industries, the processing of highly viscous or non-flowing products presents a critical challenge. Conventional mixing technologies quickly reach their limits when dealing with pasty, sticky or heavily filled materials.
The RMC Marc Guittard Z-arm mixer, also known as the Sigma Mixer or Sigma Kneader, is designed to meet these extreme challenges by ensuring homogeneous, reproducible and controlled mixing.
The Sigma Kneader Mixer is based on the principle of intensive double kneading in a horizontal mixing tank: two Z-shaped (Sigma) arms rotate in opposite directions.
The precise gap between the arms and the mixing tank also generates a shearing effect, enabling different raw materials to be homogenised effectively.
The differential speeds generate a dynamic three-dimensional mixing action.
The product is subjected to high mechanical forces, the movement of which combines compression, shearing and stretching.
The result: perfect dispersion, even for the most complex formulations.
Unlike conventional agitators, the Sigma Kneader Mixer acts directly on the material:
It is particularly effective on:
1
Introduction of the various components (liquids, powders, additives)
Option for automated feeding
2
Rotation of the mixing arms
High speed capture and incorporation of materials
3
Key stage of the process
Increase in motor torque
Gradual homogenisation of the mixture
4
Removal of agglomerates
Stabilisation of texture and properties
5
Tilting tank or screw extrusion for emptying the tank
Suitable for sticky or non-flowing products
