Scale accuracy should be verified anytime the plant is moved (portable plants), maintenance activities on the plant impact the weighing systems, or when there is a concern on scale accuracy determined from the batchman operating the batching process or the quality of concrete.
Scales For Concrete Batching Plants - Arlyn Scales
In order to gauge the right quantities for batching concrete, it is crucial that you have accurate scales for concrete batching plants. You Cannot Skimp on Scales When Your Concrete Needs to be Mixed Accurately. A concrete batching plant is a large-scale operation, meaning the entire facility will typically cost millions of dollars to build and ...

3.1.4 Calibration Overview The purpose of the plant calibration is to ensure that the plant accurately proportions the asphalt and aggregate. The belt scale, test weights and cold feed bins are part of the aggregate system and require calibration. Aggregate is diverted to a truck, the aggregate is weighed and its weight is compared
