coal wash plant water losses bauxite ore processing

Water Losses in Coal Wash Plant - Thickening, Filtering ... The water loss in coal wash plants occurs because the coal and rejects both leave the plant with more moisture than they arrive. Products tend to be centrifuged to dry the material to meet the product moisture specifi ion, while you need to do a water balance to determine how much water is being consumed. The plant flow sheet will provide this information.预计阅读时间:5 分钟
