Sigma Mixer with Extruder Screw

Product Description

Sigma Mixer with Extruder Screw

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 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.
