Introduction

In the world of industrial mixing and dispersion, the double-shaft disperser stands out as a highly efficient and versatile machine. Designed for high-speed mixing, grinding, and homogenizing, this equipment is widely used in industries such as paints, coatings, inks, adhesives, and chemicals.

What is a Double-Shaft Disperser?

A double-shaft disperser is a mixing machine equipped with two independently rotating shafts—one for high-speed dispersion and another for low-speed stirring. This dual-shaft design ensures thorough mixing, uniform particle size reduction, and efficient dispersion of solid particles into liquid mediums.

Key Components

1. High-Speed Dispersing Shaft – Typically fitted with a saw-tooth or serrated disc, this shaft rotates at high speeds (up to 1,500 RPM or more) to break down agglomerates and ensure smooth dispersion.

2. Low-Speed Stirring Shaft – Equipped with paddle or anchor-type blades, this shaft ensures consistent mixing and prevents sedimentation.

3. Hydraulic Lifting System – Allows easy adjustment of the disperser’s height for different batch sizes.

4. Control Panel – Enables precise speed adjustments and operational monitoring.

How Does It Work?

1. Loading – The liquid base and solid additives are loaded into the mixing tank.

2. Pre-Mixing – The low-speed stirring shaft blends the materials uniformly.

3. High-Speed Dispersion – The high-speed shaft activates, breaking down particles and ensuring a smooth, lump-free mixture.

4. Final Homogenization – Both shafts work in tandem to achieve the desired consistency and viscosity.

Advantages of Double-Shaft Dispersers

✅ Higher Efficiency – Dual-shaft operation reduces processing time compared to single-shaft dispersers.
✅ Better Mixing Quality – Ensures uniform dispersion with minimal air entrapment.
✅ Versatility – Suitable for a wide range of viscosities and material types.
✅ Energy Savings – Optimized mixing reduces power consumption.
✅ Easy Maintenance – Robust construction and simple design enhance durability.

Applications

• Paints & Coatings – Pigment dispersion and emulsion preparation.

• Inks – Uniform color distribution.

• Adhesives & Sealants – Homogeneous mixing of resins and fillers.

• Pharmaceuticals & Cosmetics – Smooth blending of active ingredients.

• Food Industry – Emulsification and suspension of additives.

Conclusion

The double-shaft disperser is a powerful and efficient solution for industries requiring high-quality mixing and dispersion. Its dual-shaft mechanism ensures superior performance, making it an indispensable tool in modern manufacturing processes.
