Octagonal Blender
(OB).
The workhorse of pharma blending.
Blender
Overview
Engineered for repeatability.
Octagonal Blenders tumble dry powders gently — ideal for granules and free-flowing solids where mechanical agitation would damage particles. Eight-sided geometry gives more product movement per revolution than a simple drum.
