NAUTA® – CONICAL SCREW MIXER – HOSOKAWA MICRON B.V.


The Nauta conical screw mixer is a batch mixer, specially designed for segregative, free-flowing powders and pastes.

It is a pioneer in mixing technology, named after Mr. J.E. Nauta, who developed the first conical Nauta mixer in 1939.

The Nauta conical mixer is famous for its low-intensity mixing. It is particularly suitable for mixing delicate products and processes that require very precise results. Nauta mixers are available in volumes ranging from 5 to 100,000 litres.

WORKING PRINCIPLE

The Nauta conical screw mixer is a convective mixer with high mixing efficiency. It is gentle and guarantees the highest level of mixing accuracy without product distortion. The screw has an average speed of 70 rpm, whilst the arm rotates at 1 to 2 rpm. The tip speed of the screw can fluctuate between 0.5 and 2 m/s, making it suitable for all ATEX zones.

The rotating, cantilevered (free-hanging) mixing screw conveys the product from the bottom of the vessel to the product surface. The mixing screw is suspended from an orbital arm, which rotates the mixing screw along the conical inner vessel wall, causing convective mixing of particles and shear.

The speed of particles in the downward massflow, when recirculated by gravity in a conical vessel, increases as the vessel diameter decreases. The result of these simultaneous actions is a fast and intensive mixing with low consumption of power together with high standards of mixing accuracy.

Convective mixing effect

The convective mixing effect is created by the following 3 factors:

Axial mixing by the screw
Radial mixing by shape of the cone
Tangential mixing by the arm
