HTDZ型浆料磁选机在锯泥除铁中的应用

Application of HTDZ Slurry Magnetic Separator in Removing Iron from Sawdust

对烟台牟平区某厂锯泥进行除铁试验研究,考察矿浆流速、介质选型、磁感应强度对锯泥除铁效果的影响。确定最佳磁选条件为:分选腔内矿浆流速为1.8 mm/s,介质选择2#与3#菱形网,磁感应强度为1.5 T。在工业生产中,采用0.6 T永磁筒式磁选机、1.1 T湿式强磁板式磁选机与1.5 T HTDZ-1000AF型电磁浆料磁选机相搭配的联合磁选工艺,可将锯泥精矿白度稳定在52%~55%范围,Fe2O3质量分数控制在0.51%左右,可用作陶瓷原料。

The effects of pulp velocity,medium selection,magnetic field intensity on iron removal of saw mud from a factory in Muping District,Yantai.The optimal beneficiation conditions are that the pulp flow velocity in the separation chamber is 1.8 mm/s,the medium are 2#and 3#diamond meshes and the magnetic field intensity is 1.5 T.In industrial production,the combined mineral processing technology of 0.6 T permanent magnet drum magnetic separator,1.1 T wet strong magnetic separator with magnetic plate and 1.5 T HTDZ-1000AF electromagnetic pulp magnetic separator is adopted,and the concentrate with whiteness of 52%-55%and iron content about 0.51%can be obtained,which can be used as raw material for ceramics.
