Concentric Double Shaft Mixer for Adhesive Production
A Concentric Double Shaft Mixer is an advanced mixing machine designed for processing high-viscosity adhesives, sealants, resins, and chemical materials that require strong shearing and uniform dispersion. It combines two mixing shafts arranged concentrically to create different flow patterns inside the vessel, improving material circulation and mixing efficiency. MIC Machinery provides customized mixing solutions for epoxy adhesives, silicone sealants, polyurethane compounds, and other industrial formulations requiring stable and consistent processing.
Manufacturing Process of Concentric Double Shaft Mixer
The working process of a concentric double shaft mixer mainly includes material feeding, high-efficiency mixing, dispersion, temperature control, and discharge.

1）Material Feeding
Raw materials such as resins, fillers, pigments, curing agents, and additives are loaded into the mixing vessel according to the formulation requirements. The feeding sequence can be optimized according to material viscosity and composition to improve mixing efficiency and prevent uneven distribution.
-----
2）Double Shaft Mixing and Dispersion
The inner and outer shafts rotate at different speeds to create strong axial and radial mixing forces, ensuring thorough blending of high-viscosity materials. The concentric design improves material circulation, reduces dead zones, and enhances the dispersion of fillers, powders, and additives for consistent adhesive quality.
-----
3）Temperature Control
Many adhesive materials are sensitive to temperature changes during processing. The mixing vessel can be equipped with heating or cooling jackets to maintain suitable processing temperatures, preventing viscosity fluctuations or unwanted reactions.
-----
4）Material Discharge
After achieving the required mixing quality, the finished adhesive compound is discharged through a suitable outlet system. The discharge method can be customized according to material viscosity, production capacity, and downstream filling requirements.

Technical Advantages of Concentric Double Shaft Mixer
➢ Efficient Mixing of High-Viscosity Materials
The concentric double shaft design creates strong mechanical forces, making the equipment suitable for adhesives, sealants, and chemical compounds with high viscosity or high solid content. The combination of different shaft speeds improves material movement and mixing efficiency.
➢ Improved Dispersion Performance
The interaction between the inner and outer mixing shafts promotes continuous material circulation throughout the vessel. This helps break down agglomerates and evenly distribute fillers, pigments, and additives, resulting in consistent adhesive quality.
➢ Reduced Mixing Dead Zones
Compared with conventional single-shaft mixers, the concentric structure provides more effective material exchange and coverage. It reduces areas where materials may remain stagnant, helping achieve more uniform mixing results.
➢ Flexible Process Control
Mixing speed, processing time, and temperature conditions can be adjusted according to different formulations. This flexibility allows manufacturers to optimize production parameters for product development, pilot production, and continuous manufacturing.
