自采用了芬兰塔姆费尔特公司(Tanfelt Oy)研制的滤布后,巴西矿业联合股份公司(MBR)过滤机的效果有了显著改善。到目前为止,MBR公司也和其它矿业公司一样,在圆盘过滤机上采用传统的普通滤布过滤铁精矿。普通滤布的平均寿命为600～700小时。后来,MBR公司决定试用塔姆费尔特公司研制的ELASTA滤袋,这是一种专为圆盘式真空过滤机设计的。试用效果显著:不仅滤袋寿命平均达到6000小时,过滤能力也提高了20%～30%。过滤能力所以提高,是由于获得的滤饼厚度增加,滤饼卸离过滤机更为有效。滤饼中的固体含量达到了MBR公司追求的水平,产品再加工的生产成本最低。生产总成本因而显著降低。 The effect of the MBR filter has been significantly improved after the filter cloth developed by Finland’s Tanfelt Oy. So far, MBR, like other mining companies, has also used conventional plain cloth to filter iron concentrates on disc filters. The average life expectancy of ordinary cloth 600 to 700 hours. Later, MBR decided to try out the ELASTA filter bag developed by Tamfelt, which was designed specifically for the disc vacuum filter. Trial results are remarkable: not only the average life expectancy of filter bags reached 6,000 hours, filtration capacity also increased by 20% to 30%. Therefore, the improvement of the filtration capacity is due to the increased cake thickness obtained, and the filter cake is more effectively discharged from the filter. The solid content of the filter cake has reached the level sought by MBR, with the lowest reworking cost. The total cost of production is thus significantly reduced.
