Common Failures and Solution About Magnetic Separator

The magnetic drum separator is a kind of most widely and commonly used equipment in the mining industries so as to eliminate the iron powder for the reuse of powder grain. At present, the types of magnetic separator are various at home and abroad, and classification methods are different. It can be divided into dry magnetic separator and wet magnetic separator by the sorting in the ore processing plant.

The customers often encounter problems in the use proces, such as motor overheating of magnetic separator. we summarize the the common failures and solution about magnetic separation machine:

(1) Motor overheating and abnormal of magnetic separator:

1) Lubrication of bearing is bad or wear is very serious;

2) Fan leaves fall off or wear;

3) Line contact of switch is undesirable, or break line and run single-phase;

4) Voltage is too low.

(2) The sound of magnetic separator is normal in the running, cylinder gets stuck by the barrier, and even cylinder can not turn, the bottom cases is trembling. Its reason is often that the bottom cases gets stuck by object, or magnet falls off, and make the cylinder body creaky, the serious is that the tube skin is scratched. At this time, we should stop to maintain and remove the faults.

(3) Reducer overheating reasons:

1) The oil is not enough or oil quality is bad;

2) Worm and gear seriously is worn; meshing is bad;

3) Bad bearing lubrication or severe worn.

(4) Magnetic field intensity become weak:

1) The temperature is too high;

2) Sunlight exposure;

3) Acid and alkali corrosion. Can use Gauss Meters to measure. Magnetic separator can consist of machine base, magnetic system, the cage, hollow shaft, concentrate slot, transmission equipment etc. When we install machine base, we must be based on hollow bearings to measure the elevation and levelness. The positioning of the magnetic also be based on machine base. The gap among the case and magnetic system must be accurately adjusted, its clearance limit deviation is 0 -1 mm.
