According to increase the temperature of leaching process and pressure of plate-and-frame type filter press, the moisture gradient of cake is decreased contrast to before. 通过对现场水洗加温和板框压滤机增加压力吹风,滤饼水分比改造前大大降低;
Chamber Type Diaphragm Filter Press, which was invented in mid-20~ th century, characterizes high filtration pressure, large filtration area, low moisture content of filter cake, good anti-corrosion ability and economical operation cost. 厢式隔膜压滤机是20世纪中期发展起来的,其特点是过滤压力高,单机过滤面积大,滤饼含液量低,抗腐蚀性好,运转费用低。
