Transformation of Magnetic Separator

In April 2001, 2 DPMS - φ600 mm x 1000 mm, single cylinder dry-Intensity Permanent Magnetic Separator were adopted, they completed in advance to come up from the crushing operation cycle closed lean ore particle size of -30 mm +16 mm, iron grade is 54 . 00% - 55.00% , the qualified testing and production of lump ore transformation. May 2001 production date, each year from the crushing operations to come up with the iron grade in advance 54.OO% to 55.00%. 5 ~ 60 000 t of production qualified ore, not only a benefit for more than 4 million yuan, but also reduced the secondary crushing capacity and ore had crushed.DPMS-φ300 mm × 1OOO rnm monocular dry-Intensity Permanent Magnetic Separator broken a screening-T intensity magnetic separation process to complete the -40 mm +10 mm concentrator crushing operation near the plant, in April 2002 The bonanza qualified industrial test and production upgrading of the mine. The production results show that the iron concentrate grade is 53.00% a 56 00%, than industrial production of iron grade 51 00% 53 O improved by 2-3 percentage points. Not only solving the screen wash the fine mud discharge (into the processing plant tailings),but also improving the iron grade  of jaw crusher ,and yield increase economic returns 4.96 million yuan. May-June 2002 production of iron grade is 54.50% above.
In recent years, Maanshan Iron & Steel Group Kou Shan Mining Company concentrator adopts the 15 to 6 mm DPMS-φ300 mm x 1000 mm ten style Intensity Permanent Magnetic Separator machine production targets. Dounan manganese. 30 15 mm, and 15 to a 6 mm manganese ore and third generation the DPMS plow dry Intensity Permanent magnetic separator machine selection index contrast. Magnetic field strength of the second generation of DPMS dry-Intensity Permanent Magnetic Separator ,Due to the increased magnetic field depth, the valley changed the magnetic field distribution in the separation of 30-15 mm and 15 to 6 mm manganese, with the first generation of DPMS type, The dry type Intensity Permanent Magnetic Separator separation indexes compared in the ore grade and concentrate grade is equivalent to the case of fine mineral,which increased by 6 63-11 94%, tailing grade reduced by 336-449 percent ,and the recovery rate improved about  10.90 to 19.42 percents, indicating that the third generation of DPMS dry-Intensity Permanent Magnetic Separator points selected +6 mm of weakly magnetic minerals, the separation indexes received a substantial increase.
