What is the recommended frequency for bin-discharge sampling?

The recommended frequency for bin-discharge sampling is based on ensuring accurate and representative sampling of the material being discharged from the bins. Collecting a minimum of three samples within a short period, such as 10 to 15 minutes, ensures that any variability in the material can be captured and averaged out, providing a more reliable representation of the total output.

This method accounts for potential fluctuations in aggregate quality and helps identify any discrepancies in the material composition. It allows technicians to make timely adjustments if necessary, ensuring that the resulting mixture meets specified standards.

In contrast, taking only one sample every 30 minutes may not capture enough variability over time, and collecting just two samples for the entire day could lead to an inadequate representation, potentially missing critical changes in material quality. Continuous sampling, though beneficial for some applications, may not be practical in all scenarios and can lead to unnecessary complexity without significantly enhancing quality control in this particular context.
