Sigma Mixer with Extruder

Uniform Kneading, Mixing and Extruding Process Application & Process :

The Sigma Mixer with extruder is used for mixing, kneading and extruding of highly viscous mass, sticky and dough like products, Mixing of pastes, rubber, and heavy plastic masses, applications in Food, Rubber, Pharmaceutical, Chemical and agro industries, Dry powder to wet phase mixing. This mixer is most suitable for highly viscous material and dough like masses.

The extruder mixer is designed to handle difficult to discharge products such as hot melts and butyl sealants, as well as other medium to high viscosity pastes. This type of mixer combines the action of the Double Arm Sigma Blade Mixer with an extrusion screw placed in the lower part of the mix trough. During mixing, the extrusion screw is run in reverse which imparts a third mixing action on the product, increasing mixing efficiency.

The sigma kneader is a double arm mixer with extruder, the two "Z" blade rotate towards each others at same or different speed inside a W- shaped product container and extruder screw is located between the two blade with separate gear motor drive. The extruder screw is rotates in forward direction for extruding process and rotate in reverse direction during mixing process. Speed of the extruder to be adjustable by VFD. The twin screw basin kneading machine with two horizontally arranged kneading blades, which are deeply geared into one another and strip themselves reciprocally. 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.

Sigma Mixer Operation

The extrusion screw is located in the saddle section and runs in a cylindrical trough tangential to and below the 2 mixing blades.

• When the product has finished the mixing cycle, discharge/extrusion is performed simply by running the extrusion screw in a forward direction.
• The double arm sigma blades normally continue to run throughout the extrusion process providing a thoroughly mixed product at all stages of the production cycle.
• By changing the extrusion die heads, the product can be discharged in round, square, "spaghetti", or any form desired.
• Speed variation of the extrusion screw allows adjustment of the product flow, depending on the viscosity.
