This Klinkenberg metering screw mixer and blender — sometimes referred to as a dosing screw or screw feeder — is a compact, purpose-built unit designed for the controlled, metered conveying and blending of bulk materials. Metering screw mixers of this type are widely used in food processing, chemical, and agricultural industries wherever a consistent, regulated feed rate is required.
The unit is constructed entirely in stainless steel, making it suitable for hygienic or corrosion-sensitive applications. Both the inlet and outlet are 150 mm in diameter, and the screw itself measures 150 mm in diameter with a pitch of 80 mm, a shaft diameter of 50 mm, and a working length of 1,040 mm. These dimensions point to a machine suited to moderate-throughput duties where precise material flow control is the priority.
Drive is provided by a 0.75 kW motor rated at 230/400 Volt (EEx-rated for use in potentially explosive atmospheres), turning the screw at 48 rpm. The combination of screw geometry and drive speed is calibrated to deliver a steady, predictable feed rate rather than high-volume throughput.
A notable feature of this unit is its outlet, which is equipped with a pneumatically operated butterfly valve manufactured by EBRO — a recognised specialist in industrial valve technology. This allows the discharge to be opened and closed automatically as part of a wider process line, adding a useful degree of automation and integration capability.
The machine's footprint is compact at 1.5 × 0.7 metres, with a total height of 0.8 metres, making it straightforward to install in space-constrained environments. The manufacturer's plate is missing, so the exact model or production date cannot be confirmed. The unit is offered used and is located in Barneveld, Netherlands.
