This Motan-Fuller D6320/21.6CC is a mixer and blender — sometimes referred to as a dosing or blending unit — designed for the controlled mixing and proportioning of granular or powdery plastic materials, typically within plastics processing and compounding operations. Motan-Fuller is a well-established name in industrial material handling and drying systems, serving the plastics, chemicals, and food processing industries with equipment built to demanding production standards.
At the heart of this machine is a rotary valve, constructed from stainless steel grade 1.4552, which is a robust, corrosion-resistant material suited to demanding process environments. The rotor has a diameter of 120 mm and a width of 350 mm, and it is fitted with nine locking chambers. The rotor operates at a speed of 26 rpm, driven by a 0.75 kW motor rated for 220/380 volt supply at 1,380 rpm. The unit is equipped with air-purged sealings, which help prevent material ingress into the bearing and seal areas, and a rotary valve arrangement for air transport, making it suitable for integration into pneumatic conveying systems.
The inlet has a diameter of 380 mm with inlet flange dimensions of 320 × 380 mm, and the outlet diameter is 80 mm. Installation height is stated at 360 mm. A hopper is included with the machine, measuring 650 × 660 mm, adding to the overall operational configuration. The rated capacity is approximately 20,000 litres per hour.
In terms of physical footprint, the unit occupies a floor space of 0.80 × 0.80 m with a total height of 1.10 m, making it a compact unit for the throughput it offers. The machine is serialised under number 5576 and is located in Barneveld, Netherlands, offered here in used condition from 2001.
