我厂浮选精煤用一台 PG58—2.7/6和一台Д51—2.5/6真空过滤机进行脱水作业。由于浮选生产条件变化,在浮选机之间无缓冲容器,而造成真空过滤机矿浆槽内液位忽高忽低,真空度亦随着变化,致使滤饼水份较高。再加上我厂原煤为气煤,可浮性差,精煤泡沫产品粒度细,处理能力低,这样真空过滤机成了增加浮选处理量提高全厂精煤回收率的关键设备。在“鞍钢宪法”的光辉指引下,在厂党总 I flotation plant coal with a PG58-2.7 / 6 and a Д51-2.5 / 6 vacuum filter for dehydration operations. Due to the change of flotation production conditions, there is no buffer container between the flotation machines, resulting in the fluctuation of the liquid level in the slurry tank of the vacuum filter, and the vacuum degree also changes, resulting in higher water content of the filter cake. Coupled with the coal mine for my gas coal, poor floatability, fine coal foam product size, handling capacity is low, so that the vacuum filter has become an increase of flotation capacity to improve the plant’s key recovery of clean coal equipment. In the “Anshan Iron and Steel Constitution,” the glorious guidance, the factory party total
