煤炭分选过程产品质量在线测控技术研究现状

Current Status of Research in On-line Measuring and Control Technique for Product Quality in Coal Separation

煤炭分选过程自动控制的主要目的是在保证产品质量的前提下，提高产率。分选过程中，影响分选效果的参数很多，有些参数需要稳定在最佳范围，有些参数是相关的，需要有一个最佳配合，凭人为观察和手工操作很难达到这个要求，因此，在分选过程中，根据产品质量实现自动控制具有非常重要的意义。主要论述了目前我国煤炭分选过程自动控制技术研究现状和取得的效果。

Automatic control of coal separation is for the purpose of improving productivity, while product quality must be ensured. There are many parameters that will affect the separation in the procedure of separation,among which, some must be stabilized in a optimum range and some are correlative that needs a optimum match. Human observation and manual operation can hardly meet it. Therefore automatic control is of great significance. The paper focuses on the current status and effects obtained in automatic control technique research for coal preparations in our country.
