Sigma mixer with extruder is a kind of sigma blade mixer, which is widely used in industrial production pre-mixing process, mainly used for high viscosity materials, such as chewing gum, bubble gum, toothpaste, plastic, rubber, silicone rubber, dye, pigment, ink, food glue, architectural coating, carbon, cellulose, high viscosity sealant, neutral glass glue, aluminum silver paste, silicone, etc. 

The Sigma mixer is equipped with two Sigma blades, which are used to mix the materials in the bowl. The settling speed of each blade is different. During the rotation, the two blades generate high shear forces and the material will be shredded and dropped, using two blades to get a uniform mixing effect.

The Sigma mixer with extruder is specially used for materials suitable for extrusion. The designed extruder passes through the bottom of the mixing bow and after the mixing is completed, the extruder is turned on, and the material will flow through the extruder to extrude the material. This kind of discharge is much more high efficiency, and the material coming out of the extruder can not only improve the quality of the material , but also easy to cooperate work with the next step. The extruder can also be used in reverse and forward, it is easy to clean the material in the mixing bowl and extruder to keep it free of dead corners and keep it clean.
