皖北煤电集团五沟矿井所产煤种是我国比较短缺、市场供应紧张的炼焦或配焦用煤,提高精煤质量和回收率具有重要意义。但五沟选煤厂使用的振动弧形筛由于开孔率低,筛面易堵塞,高灰细泥无法及时透筛,且随着煤质的变化及开采技术的发展,块煤含量越来越少,细粒级含量增多,已无法达到预期的脱泥效果,造成最终精煤灰分超标。为此,该矿引进了 The coal produced by Wugou Mine of Wanbei Coal and Electricity Group is of relatively short supply in our country and the coking or coke coal with a tight supply in the market is of great significance in improving the quality and recovery of clean coal. However, the vibrating arc sieve used in Wugou Coal Preparation Plant is prone to clogging the sieve surface due to the low opening ratio and the high-ash fine mud can not be sieved in time. With the change of coal quality and the development of mining technology, The less the fine-grained content increases, it has been unable to achieve the expected desilting effect, resulting in the final fine coal ash exceeded. To this end, the mine was introduced
