This Wilhelm Niemann KDV 790 is a used mixer and blender — sometimes referred to as a high-speed disperser or dissolving mixer — dating from 1994 and currently located in Barneveld, Netherlands. Dissolvers of this type are used across the paints, coatings, inks, adhesives, and chemical processing industries to disperse and homogenise solid particles into liquid media through the high-speed rotation of a toothed disc. Wilhelm Niemann is a German manufacturer with a long-standing reputation for industrial mixing and dispersing equipment, particularly within the coatings and chemical sectors.
This machine carries serial number 94.2011 and is built with a combination of hard chrome, mild steel, and stainless steel construction. It has a working volume of 800 litres and is equipped with a dissolver shaft measuring 800 mm in length, fitted with a dispersing disc of 550 mm diameter. The clearance between the shaft and the frame is 800 mm. The mixer shaft operates across a variable speed range of 290 to 1,000 rpm, with variable speed drive confirmed as fitted. The drive motor is rated at 1.1 kW, running on 380 V at 2,840 rpm, and is specified as EX-rated, in keeping with the machine's confirmed ATEX compatibility — making it suitable for use in potentially explosive atmospheres.
The unit comes with three pans, each measuring 1,100 by 950 mm, with a 60 mm outlet. Hydraulic lifting is fitted, allowing the dissolving head to be raised and lowered over the pans. A cover is also included. The machine occupies a floor footprint of 3.0 by 1.8 metres and stands to a total height of 2.2 metres.
