Moisture Mass Reconciliation Protocols in Recycled Paper Mill Furnish Audits
Auditing recycled furnish requires converting weighbridge gross mass to bone-dry fiber to prevent water inflation in CoC ledgers and commercial settlements.
Weighbridge Gross Weight
Total Truck Tonnage
Primary mass determination at paper mill receiving gates measures the combined weight of a delivery vehicle, fuel, trailer and loaded paper rolls or bales. Recording weighbridge gross weight provides the initial unadjusted mass value needed to calculate net raw material deliveries following tare weight subtraction. Heavy transport vehicles drive onto calibrated platform scales integrated into mill entrance lanes.
Certified load cells capture the total static load, transmitting weight data directly to mill inventory management systems.
Dynamic Load Scale
Electronic load cells installed under the steel or concrete weighbridge deck measure total vertical force exerted by all vehicle axles. Environmental factors such as wind load and mud accumulation on truck chassis can affect raw voltage output. Automated zero-tracking software resets the scale baseline between weighments, while side bumper stops prevent horizontal force interference from braking trucks.
Weighmaster operators verify driver documentation and shipping bills before approving the gross weight entry. Digital weigh tickets lock the recorded gross value, preventing retroactive tampering during invoice generation.
Net Fiber Audit
Subtracting the empty vehicle tare weight from the recorded gross mass establishes the net delivered weight. Moisture testing and contamination deductions apply directly to this net weight to determine final payable fiber tonnage.
