低浓度超细漂白粘土矿物的过滤问题

On the Problems in the Filtration of Low Concentration Ultra-fine Bleached Clay Minerals

厢式压滤机在高进浆压力配置回流阀和适当的过滤介质 ,可使 - 2 μm含量≥ 90 % ,矿浆浓度 15 %～2 5 %的超细漂白粘土矿物实现高效固液分离。该技术应用于工业生产 ,过滤作业回收率达 99% ,滤饼脱水率≥70 %。

Compartment filter press,when equipped with reflux valve and appropriate filtering medium at high pressure of pulp inlet,can realize a highly efficient solid liquid separation of ultra fine bleached clay minerals with a pulp concentration of 15%～ 25% and -2μm content of ≥90%?This technology when qpplied in industrial production can achieve a recovery of filtering operation of up to 99% and a dewatering rate of filter cake of ≥70%,which has provided a realistic example of realizing the industrialization of the filtration of low concentration ultra fine bleached clay minerals.
