It is important to asses primary, secondary and tertiary cutters to ensure correct contact with conveyors and evident footprints after operation. The integrity of analysis results rely heavily on all components of a mechanical sampling system operating as per specifications and the current applicable standard.
Mechanic samplers need to be complaint to the relevant standard and should be audited regularly - once per year as a minimum. Coal mines or ports that produce/use a product with a high Size / Ash Index should audit their samplers on a more regular basis - twice per year as a minimum. Large volume multi user export ports typically audit their samplers on a 3 monthly basis.
Bias testing compares the accuracy of a sample taken by the auto sampler with a sample taken from the full cross section of the conveyor belt. Typically, auto samplers are designed to operate within defined bias limits and this testing determines whether or not the sampler is meeting its design specifications.
