Sigma mixer is a twin-arm mixing device featuring two "∑"-shaped blades mounted within a W-shaped mixing cylinder. These blades rotate relative to each other at the same or different speeds. This twin-blade bowl kneader is equipped with two horizontally arranged kneading blades that mesh and alternately rotate via a deep gear drive. Each blade propels the material in the opposite direction, causing the various ingredients to continuously circulate within the tank, resulting in thorough mixing. A small gap is maintained between the blades and the tank walls, as well as between the blades themselves, to ensure excellent mixing. The shearing and tearing action generated by this small gap helps reduce the size of solid particles. Further superior mixing performance can be achieved by selecting appropriate blade structures and rotational speeds.

Sigma mixer has a wide range of applications, serving multiple industries. Whether in the chemical, dye, coating, polymer, polyester putty, plastics, pharmaceutical, or food industries, Sigma mixers can meet the mixing and kneading needs of various high-viscosity or viscous materials. Below are some of the most common applications:
Food Industry: Suitable for the processing and fine mixing of various food raw materials, such as finely milled wheat flour, white sauce, chocolate, bubble gum, chewing gum, biscuit dough, baking dough, sugar paste, and the processing of compound asafoetida and asafoetida, etc.
Paint and solvent industry: Suitable for mixing and kneading a variety of high-viscosity materials, such as polyester putty, glass putty, adhesives, sealants, glass fiber resin paste, polyester composites, primers, brake pad materials, and various resins and adhesives.
Rubber Industry: Suitable for mixing and kneading various rubber materials, such as mixing rubber solutions with silicone rubber, processing hard pastes, silicone rubber, viscous rubber solutions, sealants, and butyl rubber.
Fast-moving consumer goods industry: Applicable to the mixed processing of various daily chemical products, such as liquid soap, liquid detergent, soap granules, soap and detergent mixtures, as well as the processing of materials related to ceramic products.
Other applications: Suitable for mixing and processing a variety of materials, such as printing inks, iron compound dispersions, ceramic powders, crayon and pencil lead materials, gaskets and fillers, grinding wheel formulations, hot melt adhesives, pigments and ink products, marzipan, sealants, metal powders, molding materials, erasers, pharmaceutical preparations, plastics, putty, refractory materials, magnetic tape coating materials, ceramic materials, carbon black, carbon paste, PVC coatings, rubber composites, glass fibers, greases, lead-acid battery materials, zirconium crucibles, dough ingredients, and solid propellants, etc.
