"Stage grinding-stage PTMS magnetic separator separation process" is suitable for low-grade ore with fine disseminated grain size. In general, magnetic separation roughing is carried out after a period of grinding, discarding part of qualified tailings, and magnetic separation coarse concentrate is regrinded and reselected in the second stage of grinding (regrinding).

PTMS magnetic separator

If a large number of tailings can be discarded after separation under rough grinding conditions, it is beneficial to reduce the load of subsequent grinding and separation operations and reduce the cost. For example, aoshan concentrator adopts stage grinding process and uses large barrel diameter PTMS magnetic separator as beneficiation equipment for one-stage grinding products, so that the configuration ratio of ball mill in two-stage grinding operation of concentrator is changed from 1∶1 to 2∶1, saving grinding volume by 25%.

The final crushed product of 12-0mm is classified into 30% to 40% material of -0.074mm through the first stage of grinding, and then the qualified tailings are discharged through magnetic flume desliming and magnetic separation, and the coarse concentrate is classified into 75% to 85% material of -0.074mm through the second stage of grinding. The tailings were then discharged by magnetic desliming and PTMS magnetic separation, and the concentrate was concentrated and deslimed by magnetic deflume and then sent to filtration operation.
