应用新型磁性材料(钕铁硼永磁铁)制造了在磁选机工作间隙中产生强磁力的新一代СМБ1-63/100-H型鼓式磁选机(磁场磁感应强度为0.7T)。用该磁选机对铁合金厂中的-40+20mm和-20+5mm粒级含碳铬铁渣进行磁选,获得精矿的全铬品位分别为29.74%和26.20%,铬的总回收率分别为54.9%和69.2%。碎石中铬的品位为2.79%和2.89%(Cr2O3品位分别为4.11%和4.22%)。
A new generation of СМБ1-63 / 100-H Drum Magnetic Separator (magnetic induction of 0.7 T) was produced by using a new type of magnetic material (NdFeB permanent magnet) to generate strong magnetic force in the working gap of the magnetic separator. The magnetic separation of -40 +20 mm and -20 +5 mm granular carbonaceous ferro-slag in the ferroalloy plant with this magnetic separator yielded the full chromium grades of concentrate of 29.74% and 26.20% respectively. The total chromium recovery Respectively 54.9% and 69.2%. Grades of Cr were 2.79% and 2.89% (Cr2O3 grades were 4.11% and 4.22%, respectively).
