Level Measurement for Burnt Limestone Storage in Metal Ore Processing
Accurately measure burnt limestone levels in silos to optimize maintenance, timely cleaning, and avoid shutdowns
Monitor Silo Levels with Non-Contacting Radar Technology
Burnt limestone is stored in silos before being processed. It generates dust during the filling process and tends to stick to the silo walls, creating rat holes and build-up. As it is a critical material for the process, users need to control and monitor the actual level in the silo to prevent process stoppage. Knowing how the burnt limestone is distributed inside the silo allows detection of build-up. This facilitates scheduling of timely maintenance and cleaning to avoid unexpected interruptions of the process and associated losses in time and money.
