煤炭质量是煤炭交易和加工应用的最主要指标,通过规范的检测才能获得可靠的测试结果,在采样、制样、化验这3个检测环节中,对检测结果影响最为显著的是采样过程。文章通过研究讨论目前应用最广的几种煤流采样系统,获得了采样系统选型的基本准则和注意事项。
Coal quality is the most important indicator of coal trading and processing applications. Only through standardized testing can we get reliable test results. Among the three testing processes of sampling, sample making and testing, the sampling process, which has the most significant impact on the test results, is the sampling process. By studying and discussing several kinds of coal flow sampling systems which are widely used at present, the article obtains the basic criteria and precautions of sampling system selection.
