Coal Sampling Procedures Complete Coal Sampling

2018-3-14  Coal sampling is the first step before ordering the bulk coal material and generating power by coal. As we know, the purpose of coal sampling and preparation is to get a precision sample which can represent the entire lot. The coal sampling procedure seems like a simple procedure, but it has many rules in the sampling industry.
