选煤厂正常运转的盘式过滤机实际上并没有达到其工作极限,因为在不必化费额外费用的情况下,-28网目煤的水分还可再降低5%。水分之所以降不下来,主要是因为过滤机入料量、浓度及粒度分布的波动所致。虽然很多新建选煤厂在盘式过滤机上安装了测试仪表、但入料量和入 The proper functioning of the pan filter at a coal preparation plant has not actually reached its limit of work because an additional 5% reduction in the moisture of -28 mesh coal can be achieved without additional costs. The reason why the water does not fall down, mainly due to the filter feed, concentration and particle size distribution caused by fluctuations. Although many new coal preparation plants installed test gauges on disc filters, the amount of feed and feed
