Double Planetary Mixer for Adhesive Production
A Double Planetary Mixer is a high-performance mixing machine designed for processing high-viscosity adhesives, sealants, and chemical materials. It uses planetary mixing blades that rotate around their own axes while revolving around the mixing vessel, creating intensive kneading and blending forces. MIC Machinery provides customized mixing solutions for epoxy adhesives, silicone sealants, polyurethane materials, and other industrial formulations requiring uniform mixing, air removal, and stable quality.
Manufacturing Process of Double Planetary Mixer
The working process of a double planetary mixer mainly includes material feeding, planetary mixing, vacuum processing, temperature control, and discharge.

1）Material Feeding
Raw materials, including resins, fillers, curing agents, pigments, and additives, are loaded into the mixing vessel according to the formulation requirements. The feeding sequence can be adjusted based on material characteristics to improve dispersion efficiency and prevent uneven mixing.

2）Planetary Mixing and Kneading
3）Vacuum Mixing and Degassing
Many adhesive products require low air content to maintain bonding performance and appearance. A vacuum system can be integrated into the mixer to remove trapped air bubbles during mixing, improving product density and stability.
-----
4）Temperature Control and Discharge
A heating or cooling jacket around the mixing vessel controls processing temperature according to material requirements. After reaching the required mixing condition, the finished material can be discharged through bottom valves or transfer systems for further processing or filling.

Technical Advantages of Double Planetary Mixer
➢ Excellent Mixing Performance for High-Viscosity Materials
The planetary movement generates strong mixing forces throughout the vessel, making the equipment suitable for adhesives, sealants, and pasty materials with high viscosity. It ensures uniform distribution of fillers, pigments, and additives even in formulations with high solid content.
➢ Uniform Dispersion and Stable Product Quality
The combination of rotation and revolution allows the mixing blades to cover the entire vessel area, reducing dead zones during processing. This improves dispersion quality and helps maintain consistent viscosity, color, and performance between production batches.
➢ Effective Vacuum Degassing Capability
For adhesive applications, air bubbles can negatively affect appearance, curing performance, and bonding strength. The vacuum mixing function removes entrapped air during processing, producing a denser and more stable final product.
➢ Suitable for Various Adhesive Applications
Double planetary mixers are widely used for:
· Epoxy adhesives
· Silicone sealants
· Polyurethane adhesives
· Structural adhesives
· Electronic potting compounds
· High-viscosity chemical materials
The equipment can handle formulations containing fillers, powders, pigments, and functional additives requiring intensive mixing.
➢ Flexible Process Control
Mixing speed, vacuum level, temperature, and processing time can be adjusted according to different formulations. This flexibility allows manufacturers to optimize production parameters for new product development and large-scale manufacturing.
