芬兰 Valmet 造纸机公司研制出一种新的过滤方法,可在不耗热能的条件下对矿浆与悬浮物进行机械脱水。此法称为 Ecosuc 法,根据其原理制造的过滤机同真空圆盘过滤机类似,可用于化工、矿业与冶金。此种形式的过滤在选矿中能将固体颗粒从高浓度液体中分离出来,把滤饼水份降到很低。在这种情况下若用普通过滤方法,滤饼会含过多水份,且许多 Finnish Valmet Paper Machine Company has developed a new filtration method for mechanical dewatering of slurries and suspended solids without heat loss. This method is called Ecosuc method, according to its principle to create a filter similar to the vacuum disc filter can be used for chemical, mining and metallurgy. This type of filtration separates solid particles from high-concentration liquids during mineral processing and reduces the water content of the filter cake to very low levels. In this case if using ordinary filtration, the filter cake will contain too much water, and many
