永定庄选煤厂重介系统的完善

Improvement of the Dense Medium System in Yongdingzhuang Coal Preparation Plant

选煤厂调试是一个全方位的系统工程。本文针对永定庄选煤厂重介系统生产调试中出现的粒度超限物料进入分选系统和稀介质系统不稳定问题,结合生产实际,进行了相应的系统完善,降低了事故率,使系统生产能力很快达到了设计能力,降低了介耗,取得了良好的经济效益。

The debugging of coal preparation plant is comprehensive system engineering. In this paper, according to the problems which oversize granularity material enter into the separation system and a dilute medium system is instability in the production debugging of dense medium system in Yong - ding - zhuang coal preparation plant, combined with the actual production, has been improved and perfected. Accident rate has lowered. The production capacity of system reached the designed value. The medium consumption has been reduced, and obtains good economic benefits.
