Nauta Mixer (Conical Screw Mixer)
Precision Gentle Mixing for Delicate Powders
Nauta Mixer (Conical Screw Mixer) Overview
The Nauta Mixer is a high-precision batch mixer ideal for blending dry powders, granules, slurries, or pastes, especially when particle integrity or thermal stability is critical. Its dual rotary screw system creates a unique 3D flow pattern, resulting in uniform blending with minimal energy consumption and no material degradation.
History & Importance
The Nauta Mixer, originally developed in the 1940s by Dutch firm Nauta-Mixtures (now part of Hosokawa Micron), was invented to address challenges in mixing fragile, heat-sensitive, or dissimilar powders and pastes. Over time, its iconic conical screw mechanism became a global standard in industries requiring gentle, homogeneous blending — such as pharmaceuticals, chemicals, and food processing.
Today, PM Industries and Process Equipment Pvt. Ltd. continues this legacy by designing and manufacturing modern, customizable Nauta Mixers with advanced automation, hygienic design, and energy efficiency.
Working Principle
- A vertical screw agitator rotates on its axis.
- Simultaneously, it is carried by an orbital arm around the inner wall of the conical vessel.
- This motion lifts material from the bottom to the top, while gravity aids radial flow downward.
- The result is a gentle, thorough, and energy-efficient mix with no dead zones.
