After the iron ore has been washed out and impurities have been removed, the Andritz filter press ensures maximum dewatering of the filter cake. The newly developed feed shoe design optimises and improves the machine's performance for iron ore compared with the standard rectangular design.
In the iron ore resource estimation, the block modeling method is applied. The results showed RMSE (root mean square error) values of various estimation techniques. Based on statistical analysis, visualization of comparisons between borehole data and models, and probability plots, the accuracy of each iron ore resource estimation …
For the coarse ore (d 50 > 100 μm), which is intended for sintering, our BoVac Pan Filters provide a reliable and economical solution for filtration and dewatering. They are specially designed for the high wear and rapid sedimentation of this product. In cold climatic zones, the use of steam cabins offers the right solution to meet the transport requirements.
