Heath & Sherwood has developed an On-Line Instrument for Determining the Moisture content of granular materials' such as mineral concentrates. The instrument uses the physical properties of the material itself. That is the cohesiveness of the particles. The new technique which is not like anything on the market today measures the bulk material not just the surface plus it is not affected by the conductivity, water quality or the colour of the material. The measuring technique has been featured in Bulk Solids Handling Volume 21, Number 1/2001
