The components get abstracted from the silo by a conveyor belt (or a belt scale). The height limitation at the outlet keeps the product at a steady height. The conveyor belt pushes the iron ore, etc. equally among the slide where the moisture sensor has been integrated. That makes it possible to get a precise determination of the water content....
