  • Technical data

Two Piece Mixer

The Type Six Mixer is a traditional 2-Piece Mixer with a 3:2 (drive:driven) gear ratio and a capacity of 60 to 120ml, depending upon the type of removable blades. The 2-Piece Mixer/Measuring Head is also offered with a 2:3 (drive:driven) gear ratio for distinguishing wider differences between polymer melts.

Exchangeable Blades

Roller Blades are most commonly used for materials that require a strong shear force to form a homogenous melt: thermoplastics, and many thermosetting resins such as phenolics and expoxies...typical studies: fusion, lubricity, heat stability, crosslinking, and degradation.

Banbury Blades are desigened to duplicate the mixing action of a commercial Banbury Mixer...a medium shear-rate mixing action ideal for mixing elastomeric materials, compounding studies, and recycled materials.

CAM Blades have achieved widespread success in the Rubber Industry...a medium shear-rate blade imposing a combination of milling, mixing, and shearing forces against the test sample, alternating compacting and releasing the material within the chamber.

Sigma Blades are the original Brabender® Mixer blades developed several decades ago for the testing of flour dough...its low shear-rate design creates a tumbling and kneading force within the mixer without imposing a strong compressing force.

C.W. Brabender® mixing bowls and removable blades are cast of 304 Stainless Steel. Custom metallic and heat hardened surfaces are available upon request. A torque overload shear coupling is attached to each mixer, protecting the motor drives from torque overload and preventing damage to the Mixer/Measuring Head. The Type Six Mixer has 1 Heating Zone and can be supplied with a 3:2 or 2:3 (drive:driven) gear ratio.
