SKT复振跳汰机在阳城煤矿选煤厂的应用

Application of SKT complex vibration jigger in Coal Preparation Plant of Yangcheng Coal Mine

阳城煤矿选煤厂由于原煤煤质变化较大且细粒煤较多,加上设备使用年限较长,造成洗选过程中设备分选精度低,中煤产品中夹带精煤比例较高;为解决此问题,更好地适应煤矿原煤性质的变化,采用SKT复振跳汰机作为该厂改造升级的主选设备。实践表明,中煤夹带精煤比例由原来的33.03%下降到16.01%,降低了精煤损失,提高了选煤厂经济效益。

In the coal preparation plant of Yangcheng Coal Mine,due to large changes in the quality of raw coal and more fine-grained coal,and the long service life of the equipment,the separation accuracy of the equipment in the washing process is not high.And the proportion of clean coal in middling is higher,causing a certain loss of clean coal.In order to solve the above problems and better adapt to the changes of raw coal,the SKT Complex vibration jigger is used as the main selection equipment for the transformation and upgrading of the plant.Practice has shown that the proportion of clean coal entrained by middling has dropped from 33.03%to 16.01%,which reduces the loss of clean coal and improves the economic benefits of the coal preparation plant.
