How often should on-belt samples be collected?

Collecting on-belt samples at a minimum of three samples within a 10-15 minute timeframe is essential for ensuring representative testing of the aggregate. This method allows for capturing variations in the material being processed, which can occur due to fluctuations in the production process or the characteristics of the materials themselves. By gathering multiple samples in quick succession, it increases the likelihood of detecting inconsistencies or variations in the aggregate's properties, thereby providing a better overall assessment of the quality of the mixture.

This approach supports the quality control process by allowing technicians to make timely adjustments if deviations from required specifications are identified during sampling. It's a practice designed to optimize the accuracy of the results and ensure that the aggregate meets the standards required for construction purposes. Other sampling frequencies may not provide the same level of details about the consistency of the material, which is crucial in effective aggregate management.
