Mass-based sampling of primary subsamples
Author: technological excellence Date: 2019-11-27
The primary sub-samples are taken at a preset quality interval, the first sub-sample is taken randomly within the first mass interval, and the remaining sub-samples are taken at equal quality intervals. You can use a variable speed or fixed speed sampler for sampling. If the pre-calculated number of sub-samples has been collected but the coal in this sampling unit has not yet flowed, sampling should continue at the same quality interval until the coal flow ends.
