Reducing medium consumption is a key of reducing refinedcoal cost heavy media coal preparation plant.
降低介质消耗是降低重介选煤厂精煤成本的关键。
2
After using the fuzzy-PID control system, the stability of the refinedcoal quality is guaranteed and the recovery ratio is increased.
选用基于模糊理论的PID控制系统后，有力地保证了精煤质量的稳定和回收率的提高。

The mesophase pitch derived from refinedcoal tar Pith has a higher spinning temperature during melt-spinning, which is unfavorable to stable continuous spinning.
