The characteristics of PTMS magnetic separation equipment play a role in improving the concentrate grade in the mine

PTMS MAGNETIC SEPARATOR
what is magnetic bead separation?
PTMS magnetic separator, through the control device to the magnetic system to direct current, in the sorting cylinder generated from bottom to top repeatedly alternating magnetic field, the sorting material repeatedly magnetic agglomeration - dispersion - magnetic agglomeration, while applying from bottom to top washing water to the material for washing. PTMS magnetic separator can remove the iron inside (Fe2O3). The magnetic group formed by magnetite is discharged from the concentrate discharge pipe at the bottom under the action of magnetic field and gravity. Kaolin, potash albspar, quartz sand can be repeatedly selected in the separation cylinder, the lean intergrowth and monomer gangue can be fully sorted out, so the concentrate grade is higher, and the magnetic agglomeration can capture fine magnetite, so the recovery of magnetite is also higher. PTMS magnetic separator can remove the iron inside (Fe2O3). Low grade magnetite concentrate can be cleaned by PTMS magnetic separator, which can increase the grade of magnetite concentrate from 50% ~ 63% to 65% ~ 68%.
PTMS pulse magnetic separator, its sorting process, the magnetic particles formed by the magnetic group can constantly shake under the action of the magnetic field, and under the combined action of the magnetic field and gravity to move rapidly downward, in part of the sorting space magnetic agglomeration in a strong "a relaxed" and rotating turbulent state. PTMS magnetic separator can remove the iron inside (Fe2O3). When the concentration of the material in the separation space reaches a certain degree, the separation process is accelerated. A laboratory test was carried out on the regrinding and reseparation concentrate of a mine tailings by PTMS pulsed magnetic separator. The ore grade was 44%, the concentrate grade reached 62.5%, and the recovery rate reached 91%. The separation test under different conditions for the fine screened ore from a concentrator shows that the grade can be increased by more than 5% and the rate of fine ore can reach more than 70%.
Using magnetic field screening separation theory production PTMS magnetic field screening machine, and the biggest difference between the traditional magnetic separator is directly without magnetic field, but in the equivalent of a weak magnetic separator dozens of uniform magnetic field, using the monomer of iron ore and even had body mineral magnetic differences, make the implementation effective monomer magnetic minerals reunion, increase and even the living body of the difference in size, density difference, Then the special screen installed in the magnetic field, the mesh size is many times larger than the largest particle size in the mine, so that the magnetite formed a chain magnetic polymer on the screen, along the screen surface rolled into the concentrate box; The monomer gangue and connective bodies exist in a dispersed state due to weak magnetism, and are easily discharged into the middle ore box through the sieve hole. PTMS magnetic separator can remove the iron inside (Fe2O3). Therefore, PTMS magnetic field screening machine can effectively separate gangue and connected body more than magnetic separator, so that the grade of iron concentrate can be further improved, and it is suitable for a wide range of feeding granularity, as long as it has been separated from the magnetite monomer can be recovered for concentrate, only to affect the grade of connected body grinding and re-separation can be. PTMS magnetic field screening machine has achieved good results in the test and application of many domestic iron ores, and the concentrate grade can be generally increased by 2% ~ 5%.
