Iron ore, coal, quartz sand and other components are mixed and sintered. In the next step, this mixture is melted in a blast furnace. The RGI sensor determines the residual moisture of these products in real time before they are mixed. Components are extracted from the silo by conveyor belts (or belt scales). Height restrictions at the exit keep the product at a stable height. The conveyor belt pushes iron ore etc. evenly into the chute with integrated humidity sensor. This makes it possible to accurately determine the water content
