When your process requires heavy-duty mixing of highly viscous materials, double arm mixers provide the robust performance needed for demanding applications. With over 47 years of experience, IPP offers one of the world’s largest inventories of used process equipment, sourced from 20 complete plant sites and featuring over 15,000 ready-to-ship pieces. Our selection of used double arm mixers ensures companies can source reliable equipment while reducing costs and lead times.
Double arm mixers, also called sigma blade mixers, use two counter-rotating blades within a U-shaped trough to knead, blend, and homogenize thick, heavy materials. This high-torque design excels at processing materials that would overwhelm traditional mixers, making double arm mixers indispensable in rubber, adhesives, plastics, and specialty chemical industries.
Double arm mixers are built with durability in mind, using materials matched to the abrasiveness, viscosity, and cleanliness requirements of the process:
