The properties of magnetic clusters or chains differ from those of individual ore particles and can affect subsequent screening, grading and PTMS magnetic separator operations. The following cases are analyzed: after magnetic separation, there is grinding classification. For example, the magnetic pulley preseparation is followed by grinding classification or the re-grinding classification of the magnetically separated coarse concentrate in the stage grinding process.
If the ore or magnetic coarse concentrate after magnetic pulley separation has more residual magnetism, there is still magnetic agglomeration phenomenon after grinding into the classifier, the magnetic group is generally more loose, which contains more water, the magnetic group will enter the overflow when using hydraulic classification, and the magnetic group will enter the product on the screen when using the sieve classification. PTMS magnetic separator Less remanent magnetic separator after iron removal.
As a result, particles that should go into the return sand enter the overflow with the magnetic mass (spiral classifier or hydraulic spiral), and the magnetic mass that should go under the screen enters the screen, which reduces the classification efficiency. In severe cases, the spiral classifier may not return sand, in which case a demagnetizer must be used to eliminate magnetic agglomeration. PTMS magnetic separator solves this problem.
