Shuichang Iron Ore of Shougang Mining Company ，Qian’an Hebei 064400，China ） Abstract ：CT-1627 permanent magnet magnetic pulley is the largest specifications and the largest capacity of the dry separation equipment in domestic ，the mechanical structure is designed in large scale and the large magnetic pole is adopted in magnetic system ，which is designed by using the method of calculation of the COMSOL Multi -physics analysis software simulation. CT -1627 is applied in the dry sorting system of waste rock recycle in the Dongpai stope of Shougang Shuichang plant ，the average tailings grade is 4.18% less than 6.5% which is the dry waste standards. About 70 million tons of the ore with the grade range from 20% to 30% is recovered in eleven months ，which has been generated about 56 million Y
