Coaxial Dual-Shaft Dispersion Mixer

The coaxial dual-shaft dispersion mixer is a product that integrates dispersion, wall-scraping, and vacuum functions. During the dispersion process, the wall scraper rotates along the inner wall of the barrel, creating a certain radial mixing effect. The PTFE scraper blade effectively scrapes material off the barrel walls, making it highly adaptable to medium and high-viscosity or thixotropic materials. The final product discharges cleanly, and the mixing barrel is easy to clean.

With a vacuum-sealed design, the mixer can be equipped with a vacuum pump or pump system, achieving a maximum vacuum level of -0.098 MPa (20 mbar). It is suitable for special operating conditions such as vacuum defoaming, vacuum feeding, and inert gas protection during dispersion and mixing.

Working Principle

The dispersion disc operates at high speed, causing the material to form a ring-shaped flow and generating a strong vortex. This vortex spirals downward to the bottom, where intense shear, impact, and friction occur between particles, enabling rapid dispersion and dissolution.The PTFE wall scraper rotates tightly against the barrel wall, effectively scraping off material from the walls. This eliminates material adhesion issues and accelerates material circulation.A hydraulic pump drives the hydraulic plunger for lifting and lowering, moving the entire transmission mechanism, working unit, and sealed lid. During operation, the barrel lid and the cylinder achieve an airtight seal. Combined with the vacuum system, this ensures effective vacuum dispersion.


High Dispersion Efficiency

The equipment achieves a linear speed of over 20 m/s, allowing powder to be quickly and thoroughly dispersed into liquid materials.


Clean Discharge and Easy Maintenance

The scraper design effectively eliminates material adhesion to the barrel wall. The adjustable scraper adapts to the barrel surface based on material resistance, ensuring a long service life. Additionally, the bolt-mounted scraper design allows for easy replacement.


Excellent Environmental Performance and Safety

The mixer is equipped with a sealed lid that moves with the lifting system, ensuring an airtight connection with the mixing barrel and achieving extremely high vacuum levels. This effectively prevents solvent evaporation. The lid features a sight glass and spotlight for real-time monitoring of the mixing process. It also includes a sanitary-grade manhole for cleaning and feeding operations.


High Customizability

The equipment supports various non-standard customizations, such as explosion-proof designs and multi-barrel compatibility. Materials can be customized to meet specific requirements, including SS321 and SS316L stainless steel.
