一、概述为降低灰分和提高精煤产率,用浮选法处理煤泥获得了日益广泛的应用。浮选精煤通常用过滤机脱水以降低其水分,最常用的过滤机是各种类型的真空过滤机。使用真空过滤机对煤泥进行脱水时,单位滤布面积的处理量偏低,产品水分偏高, I. Overview In order to reduce ash and improve the yield of clean coal, flotation method used to deal with the increasingly wide range of applications. Flotation of coal is usually dehydrated with a filter to reduce its moisture, the most commonly used filters are various types of vacuum filters. The use of vacuum filter for dehydration of coal slime, the unit volume of filter cloth handling capacity is low, the product of high moisture,
