measuring moisture content in coal stockpile

Moisture Content

2000-3-30 · The moisture content of aggregates in the field is much closer to the SSD state than the OD state. The bulk specific gravity (BSG) of aggregates is more accurately determined by the displacement method in the SSD condition. The moisture content can be calculated directly from measurements of (BSG) using the displacement method.
