The robust solution for sampling of hot powder material from the production process

Area of application

Sampling of powder material from vertical or inclined drop chutes

Powder (hot meal and other, feed size max. < 200 µm, temperature max <900°C)

Operation mode
Automatic, manual


Optimized for sampling of hot powder material
The HR-KNH sampler is designed for the sampling of hot powder and fine-grain material from inclined drop shafts. A linear conveyor transports a spoon into the material stream. After the retraction and unloading of the spoon, the material falls through a funnel into the sending station. The system can be used for both cross-sectional and random spot sampling. The sample quantity can be adjusted by control of the sampling strokes. The sampling cycle can be controlled by the PLC of a process station.

Flexible configuration
Optionally, the HR-KN/H is available as an extra-robust version with hydraulic drive and welded frame. Furthermore, a water-cooled feeder is obtainable as an additional sample cooling device. Usually, the sampler HR-PN is linked to the plant station HR-BM. Here, the sample can be collected within the mixer. Alternatively, the material can be filled directly into a pneumatic carrier or cup for transportation into the laboratory. Optionally, the sample can be filled into a collecting container without plant station.
