1. Frame
The basic frame supports the entire machine's weight and ensures the stability of 5L sigma mixer during operation. Made of thickened carbon steel or stainless steel welded construction, it's sturdy and durable.
2. Mixing Cylinder
Sigma mixer's cylinder features a W-shaped design for holding materials. The interior can be polished or treated with a non-stick coating for easy discharge and cleaning.
3. ∑-shaped Blades
Main component of sigma mixer, these blades typically feature two ∑-shaped blades rotating in opposite directions. Using varying speed ratios, they provide intense shearing, kneading and mixing of materials.
They are particularly suitable for high-viscosity, paste-like materials (such as adhesives, sealants and resins).
4. Transmission System
Transmission system consists of a motor, a reducer and gears, which drive the ∑-shaped blades to rotate, ensuring that sigma mixer has sufficient torque to handle high-viscosity materials.
5. Discharge System
5L sigma mixer often features hydraulic tilting discharge system, making it convenient for users to sample or unload small quantities and multiple times.
6. Heating and Cooling Jacket
The outer wall of mixing cylinder can be jacketed to support electric heating, thermal oil heating, or water cooling, ensuring that the material is processedat the required temperature.
7. Sealing System
Mechanical seal is designed at the contact point between the blade and sigma mixer body to prevent material leakage. Sigma mixer can be equipped with a vacuum seal to support mixing in a vacuu, environment and prevent air bubbles.

1. Frame
The sturdy stainless steel or carbon steel frame ensures stable operation of double planetary mixer. It can be used with press machine, which is level with the mixing system, and the cylinder that moves on rails.
2. Blades
Commonly used blades include folding blades, twist blades or claw-shaped blades. These blades can be customized based on the material;s characteristics and can be equipped with high-speed dispersing disc and scrapers. The blades simultaneously rotate and orbit around the container, creating powerful stirring and scraping. The speeds of both revolutions and rotations can be adjusted via a frequency converter, achieving a combination of high-speed dispersing and low-speed mixing.
3. Mixing Cylinder
Typically made of SS304/316, it can be jacketed for heating or cooling. The inner wall of double planetary mixer cylinder is mirror-polished to eliminate dead corners and ensure uniform mixing of materials.
4. Driving System
Motor+reducer combination ensurs strong torque output, making double planetary mixer suitable for handling high-viscosity materials. A frequency converter controls the mixing speed to meet diverse process requirements.
5. Lifting System
Hydraulic lifting facilitates container entry, exit and cleaning. A safety lock prevents accidental dropping during operation.
6. Vacuum System
Mixing cylinder can be evacuated to remove air bubbles and improve the density and clarity of the finished product. The vacuum level can reach -0.098MPa.
7. Heating and Cooling Jacket
Mixing cylinder jacket can be fed with thermal oil or cooling water to meet material temperature control requirements. It is suitable for the production of thermosetting adhesives or adhesives that require cooling and curing.
