Overview of mobile coal flow sampling methods
Author: technological excellence Date: 2019-11-27
Mobile coal flow sampling is performed in a time-based or mass-based system sampling method or a stratified random sampling method. From the perspective of convenience and economy, time-based sampling is better.
When sampling, ensure that a complete cross section of coal flow is taken as a sub-sample, and the sub-sample cannot fill the sampler and overflow from the sampler.
As far as possible, samples shall be taken from coal flows with relatively uniform flow rates and loads. The load flow and quality change period of coal flow should be avoided to coincide with the running period of the sampler to avoid sampling bias. If it cannot be avoided, you should use stratified random sampling.
