Rotating Cone Sampler
Multotec’s Rotating Cone Sampler provides a dry continuous discharge sample at division ratios up to 1000:1 (or tailored for applications), enabling online analysers or mineral processors to achieve accurate real time process monitoring.
It features custom-designed radially tapered cutters travelling at speeds of down to 0.2 m/s on the critical diameter, across both stages of the sample extraction, enabling continuous representative sampling from vertical falling streams under gravity. Primary and secondary cutters are designed to rotate at unrelated ratios to each other to prevent cyclic and short-term periodic sampling errors. Perfect symmetry also sees adherence to correct sampling practices.
The unit also allows for immediate rejects return to the main stream flow without additional rejects considerations.

Engineered to increase your processing performance
On-line analysers are becoming increasingly important for real time process monitoring. A typical online analyser cannot handle the volumes of a primary slurry feed; thus a representative sample needs to be taken for accurate and precise reporting.
Multotec’s Rotating Cone Sample is an extension of Pierre Gy’s Theory of Sampling, enabling true, representative sample streams to be extracted continuously. It features a mechanically suited distribution cone, manufactured from a range of materials, stainless steel cutter blades (with optional replacement hoods) and robust pinion gear drive design with high torque factor to cover most applications.
