Level Measurement for Aggregate and Rock Silos in Coal Processing
Accurately measure levels in aggregate and rock silos to ensure capacity is available as needed for production.
Silo Level Monitoring with Radar and Point Level Technologies
As the coal is screened, extra materials are diverted to a separate silo. The aggregates and rocks create a very uneven surface, making level measurement a challenge. It is important for operators to know the available storage capacity of the silo to prevent process disruptions.
