Dry magnetic separator common faults and solutions


Dry magnetic separator common faults and solutions


(1) The magnetic separator motor is overheated and its sound is abnormal.


The reason why the magnetic separator motor overheats and its sound is abnormal is: 1) the bearing is poorly lubricated or the wear is serious; 2) the fan blade is detached or worn; 3) the switch circuit is in poor contact, or the single line is broken; 4) the voltage is too low .


(2) The magnetic separator is not sounding properly during operation, the cylinder is caught by the obstacle, and even the cylinder cannot be rotated, and the bottom box vibrates.


The reason is often that the object in the bottom box is stuck, and then the magnetic block is detached, so that the cylinder creaks, and in severe cases, the barrel is scratched. At this time, it should be stopped for maintenance and troubleshooting.


(3) Reducer overheating


The reasons are as follows: 1) insufficient oil or poor oil quality; 2) excessive wear of gears and worms, or poor meshing; 3) poor lubrication or wear of bearings.


(4) Magnetic field strength of magnetic separator is weakened


The reasons are: 1) the temperature is too high; 2) the sun is exposed; 3) the acid-base corrosion. Can be measured with a Gauss meter
