南屯煤矿选煤厂自动配煤系统的设计与应用

Design and application of automatic coal blending system in Nantun mine coal preparation plant

为解决南屯煤矿选煤厂无法均质配煤的问题,从自动配煤的理论研究出发,设计了返煤自动配煤系统。介绍了自动配煤系统的组成、控制原理、系统功能,并分析了该系统在南屯煤矿选煤厂的应用效果。生产实践表明:自投入使用后,自动配煤系统运行平稳,实现了不同煤质煤炭的自动掺配,且配煤合格率高,配煤平均灰分完全满足需求。

To solve the problem of unevenly blending coal in Nantun mine coal preparation plant,automatic coal blending system is designed based on theoretical research. This paper introduces composition,control pricinple,function of this system as well as analyzes its application effect. The result shows that the automatic coal blending system can operate steadily; different coal can be blended automatically with high qualified rate,also ash content of coal blending is qualified.
