A roller screen is usually attached to the exit to separate pellets within the desired range from undersize and oversize, the latter two streams being recirculated (oversize after being crushed). The recirculating load tends to be approximately 150–250% by weight of feed. Although a rotary drum pelletizer requires a roller screen

    Use of Iron Ore Pellets in Blast Furnace Burden

    13/06/2014· In 1943, Dr. Davis, a professor at the University of Minnesota, Mines Experiment Station, invented a method for processing taconite containing low grade iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as 0.1 mm or less, which are not suitable for
