The Necessity of Scales in Concrete Batch Plants

Concrete is a relatively simple mixture that without the right measurements, can create big problems for the project it is being used. Concrete is created from aggregate, sand, cement, and water at a batch plant. Scale technology is used at batch plants to verify proper ingredient amounts are combined to produce the desired end result.  Loadcells are located on bins or hoppers to weigh the elements of the mix.  It is crucial that moving parts of the batching system are inspected regularly for buildup, seizing, imbalance, and other issues.

Prior to production at a batch plant, Scale Technicians will visit to test and calibrate scales and loadcells. This calibration involves the customer, technicians, county sealer, and the district DOT representative. This large coordinated effort is done by Brechbuhler Scales.  Each party involved needs the appropriate information prior to beginning production. Scale Technicians will first do a mechanical test to make sure all parts are moving correctly. Then, the Scale Technician will hang weights from the loadcells via chains to test accuracy. Calibration occurs if a loadcell is not weighing properly.  Assuming improper weighments, the loadcell will be tested further until it meets the compliance of all parties involved.  Finally, because water is a crucial part of the concrete mixture, the scale technicians can also go to the water source and verify flow. By checking the water source with a flow meter, we further isolate any potential future batching issues. 

Accurate weighing ensures that your concrete mixture, whatever grade it might be, is safe and effective. If mismeasured concrete gets poured, the faulty concrete becomes a safety risk – many times it will dry or form properly. Concrete plant cement must be safe and effective.  Safe and effective means scales and loadcells are accurate each and every weighment.
