Used Nauta mixers are vertical, conical screw mixers designed to gently mix powders, pastes, and slurries while preserving particle integrity and preventing segregation. The combination of axial and radial flow creates a low-shear blending action that is ideal for fragile, segregative, or heat-sensitive materials. With more than 47 years of process expertise, IPP supplies used, secondhand and surplus Nauta mixers from 20 global process plant sites and maintains a world-class inventory of 15,000+ ready-to-ship systems.

IPP sources Nauta-type mixers from trusted manufacturers including Hosokawa Micron, Bolz-Summix, and De Dietrich Process Systems.
