Research and Application of the Adjustment of the Primary Dry Magnetic Separation Process of Anhui Development Mining
In order to improve the raw ore grade of Anhui Development Mining Co.,Ltd.and reduce the cost of direct beneficiation,the test of pre-discarding tailings treatment conditions are carried out.The effects of magnetic deflection angle of CTDG1218-6000Gs dry magnetic separator,frequency of belt fre-quency converter and position of separation baffle on dry separation index are analyzed.The results show that the dry separation index is the optimum when the magnetic declination of the dry magnetic separator is 85°,the frequency of the belt frequency converter is 42 Hz,and the position of the separating baffle is in the original position(1 400 mm horizontally from the center of the dry magnetic drum,1 000 mm longitudi-nally).After the optimization of the process,the annual production cost can be saved by 600.5 thousand yu-an,and the waste rock thrown out for the construction industry can increase the annual income by 797.4 thousand yuan.It is of great significance to study and apply the process parameters adjustment of dry mag-netic separator.
