2012-1-1  Binder (bentonite or organic) and possible additives are fed in the slurry and mixed before filtering. The filter cake is transported to large balling drums or balling discs to be rolled to green pellets. The green pellets are screened to 9–11 mm diameter. The oversize is crushed and fed together with the undersize back to balling.

After the taconite has been milled to a fine powder and separated from the waste powder, it is poured into a balling drum. Here, the taconite is mixed with a binder, or "glue," and rolled into small, round pellets about 1/2" in diameter. The pellets are baked and hardened. the hardened pellets are then shipped to steel centers, where they are ...
