PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. As to the 3 – 0 mm the roller mill whose grade is 26.27%, the Magnetic Separator tailing, pre-cast addition to preselected yield 47.80%, qualified dam grade is 831%. It can be said that the research has created a new situation for the utilization of depleted iron ore.Tailing ore pre-selection greatly improve the grade into the mill, at the same time enhance Washan ore processing capacity of the concentrator, and reduces the operating costs of grinding and separation, mining companies, Nanshan Experimental Research after in-depth exploration and repeated several times, made a breakthrough progress, that is, using the high-pressure roller mill and linear screen closed circuit crushing system to continue the three stage crushing Washan Concentrator 20-0 mm ore crushed to 3 to 0 mm, strong magnetic separator and wet midfielder the tailing sorting, rough concentrate regrinding the re-election of iron concentrate grade 65. OO %.
