Prep-Mixer®

Prep-Mixer®

The Prep-Mixer® is C.W. Brabender's largest Mixer/Measuring Head. It is a 3-piece design with a capacity of 350/420ml depending on mixer blade configuration.

Ideally suited for preparing laboratory batch samples of thermoplastic and elastomeric compounds.

Prep-Mixer® 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.

 

Technical Data

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 Prep-Mixer® can be supplied with a 3:2 or 2:3 (drive:driven) gear ratio.
