iron ore classification equipment
Advances in screening technology in the mining sector
A total of 6 parallel lines process 9500 t/h of ore. Screening equipment is installed after the primary crusher, after the scrubber and after the tertiary comminution stage to separate the iron ore into a dry coarse fraction (8 – 40 mm) and a wet fine fraction (> 1 – < 8 mm). The fraction < 1 mm passes through another washing stage.
