This Hosokawa Nauta MBX R is a mixer and blender — sometimes referred to as a conical mixer or Nauta mixer — designed for the blending and mixing of bulk materials in powder, granule, or paste form. Hosokawa is a well-established manufacturer of particle processing and powder handling equipment, with the Nauta range being widely recognised in industries such as food processing, chemicals, and pharmaceuticals for its conical screw mixing technology.
This is a large-capacity unit with a working volume of 4,850 litres, housed in a conical vessel with a maximum cone diameter of 2,000 mm and a cone height of 2,800 mm. The vessel is constructed from stainless steel grade 1.4541 (equivalent to AISI 321), a stabilised austenitic steel well suited to applications requiring corrosion resistance and elevated-temperature service. The vessel is equipped with a jacket of 392 litres capacity, allowing thermal control of the mixing process, and is rated to a working pressure of 0.01 bar internally and 0.4 bar on the jacket side. The maximum operating temperature is stated at 20 °C.
Drive is provided by a 15 kW motor rated for 380–415/660/720 volt supply, mounted in a top-drive configuration. The bottom of the cone features a pintle bearing arrangement, which is standard practice on conical mixers of this type to support and guide the rotating screw. Access to the vessel interior is via a manhole of 500 mm diameter, and discharge is handled through a sliding valve outlet of 250 mm diameter.
The unit is mounted in a frame and stands on legs, giving a total installation height of 5.4 metres with a floor footprint of 2.5 × 2.5 metres. Located in Barneveld, Netherlands, this 1987 machine carries seller reference number 86132 and is offered in used condition.
