峨口铁矿铁精矿压滤性能研究

Research on Press Filtration Performance of Ekou Iron Concentrator

针对太钢集团峨口铁矿选厂使用圆盘真空压滤机处理铁精矿存在的滤饼水分过高的问题,采用KM9/1000型快速压滤机进行了实验室压滤试验。结果表明,在滤腔深度为40mm,入料压力为0.8MPa,压榨、吹饼压力均为0.5MPa,压榨、吹饼同时进行的隔膜压滤方式下,可使滤饼水分降到8%以下。按相同压滤方案在峨口铁矿选厂进行现场试验,获得了滤饼平均水分为7.3%,单位处理量为408kg/(m^2·h)的试验指标,验证了采用KM型快速压滤机处理峨口铁矿铁精矿的可行性。

In view of too high moisture of iron concentrate cake of disk vacuum filter press in Ekou Iron Concentrator, Tai Steel Group, laboratory press filtration test was made using KM9/1000 rapid filter press. The results showed that the cake moisture was reduced to below 8% at a filter chamber depth of 40 ram, feeding pressure of 0.8 MPa, simultaneous cake pressing and blowing at 0.5 MPa under diagram press filtration mode The site test on the same press filtration scheme was carried out in Eokou Iron Concentrator, an average cake moisture of 7.3 % was obtained at a unit throughput of 408 kg/ （ m^2 · h）, validating the feasibility of using KM rapid filter press to treat Ekou iron concentrate.
