SFM4 - Screw compaction unit
The SFM4 bypass screw compaction unit has to be placed in a free fall situation of material, e.g. in a drop shaft. A partial flow of this material is trapped in the first section of the compaction unit. The screw compactor compresses the material and conveys it into the second part of the unit, right across the installed ACO moisture sensor for the determination of the residual moisture. Then the material falls down through a drop pipe back into the process. Based on this constant and equal conditions (density, dumping height, etc...) precise measuring results are available.
