摘　　要：为解决难过滤矿物脱水的难题,通过对高效压滤脱水工艺的研究、高效压滤机的设计研究、压滤机的大型化研究、压滤机自动控制系统及脱水过程控制优化的研究,成功开发出了大型高效的BPF自动压滤机及配套脱水系统。在选矿厂精矿脱水的工业应用证明,脱水后获得的滤饼水分可达8.0%左右,明显低于真空过滤的15.0%。单位过滤面积处理能力达300～450kg/m2.h,明显高于普通板框压滤机的单位过滤面积处理能力。To resolve the dewatering problem of difficult-filtering mineral, the highly-efficient dewatering technics, pressure filter plate enlarging technics, automatic-control system of pressure filtering and the optimization of dewatering process were researched. And by these researches, the large-scale and highly- efficient BPF automatic pressure filter and associated dewatering system were developed. The moisture of filtering cake by the BPF operating in dewatering concentrate is about 8.0%, which is lower than the vacuum filter of 15.0%. Processing capacity of BPF is 300-450 kg/m2·h, significantly higher than ordinary frame pressure filter.
