Breaking Down the Details: Caframo’s High-Performance Dispersion Blades

Dispersion blades, also referred to as Cowles-style blades or sawtooth impellers, are critical tools in high-shear mixing processes. Known for their use in particle size reduction, emulsification, and homogenization, these blades are indispensable in industries like cosmetics, chemicals, pharmaceuticals, and coatings. Caframo is thrilled to introduce the versatile A431 (3″) and A441 (4″) dispersion blades, as well as the comprehensive A400SET, designed to meet a wide range of mixing requirements in your lab or R&D environment.

What Do Dispersion Blades Achieve?

Dispersion blades operate by generating intense shear forces through their sawtooth design. As the blade rotates at high speeds, it draws materials into the vortex it creates, subjecting them to extreme shear. This process breaks down particles, disperses powders, and ensures a uniform distribution of materials—crucial for dissolving solids and forming stable emulsions, especially in low- to medium-viscosity liquids.

Why Choose Caframo’s New Dispersion Blades?

• High-Shear Efficiency: The A431 and A441 models provide reliable, fast particle dispersion and homogenization, particularly for scaling up production in larger batch sizes.
• Ready to Mix: Seamlessly integrating with Caframo’s overhead stirrers, these blades are a cost-effective solution, eliminating the need for additional equipment or complex adjustments.
• Built for Durability: Constructed with a welded hub, these blades are designed to withstand rigorous usage and high-torque applications, making them an excellent choice for challenging materials and extended use.

How Dispersion Blades Work

The sawtooth geometry of these blades creates high-shear zones where materials are forced through narrow gaps at high velocity. This action is especially effective for reducing particle size and ensuring even distribution across hydrating powders, gels, thickeners, etc.

New Sizes for Enhanced Versatility

Caframo’s A431 (3″) and A441 (4″) blades allow users to scale up without compromising the consistency and quality of high-shear mixing. The A400SET, which includes three blade sizes (A164, A431, A441), offers unmatched flexibility, making it ideal for labs needing to accommodate various batch sizes and mixing applications.
