Daily Maintenance Of The Magnetic Separator
With in-depth development of the domestic and foreign high-performance permanent magnet materials
, the industrialization of magnetic separation equipment as well as the constant optimization, upgrade and promotion of traditional permanent magnetic separator magnetic system and body structure has accelerated the process that permanent magnetic separator equipment gradually takes place of electromagnetic separation equipment. With the application of automatic control technology and monitoring technology in domestic and foreign mining enterprises, the automation level of mining equipment manufacturing is improved correspondingly and the accuracy requirements of the field of magnetic mineral separation is becoming higher and higher. Currently, the development tendency of magnetic separator mainly includes the following four trends:
1.The refinement of magnetic separation equipment
2.Equipment to be large-scale
3.Equipment is to be updated
4.The automation of equipment
The Magnetic Separator is suitable for wet magnetic separation of materials such as magnetite, calcined ore, etc. and it can remove the iron in the coal, non-metal and construction industries. The magnetic system is made from high quality ferrite magnetic materials and /or rare earth magnet steel. On the shell surface, the magnet intensity is 100-600mt. The wet type permanent magnet cylindrical separator is commonly used for iron ore separation. It is suitable for separating materials with high magnetism. In recent years, it has been used as concentrating equipment in place of magnetic dewatering cell.
Advantages:
1)Short magnetic circuit,
2) little magnetic flux leakage
3) high magnetic intensity
4) low energy consumption
5) fine beneficiating results
6)simple structure and easy to maintain.
User frequently encounter motor overheating and other issues, the following is the summary of common faults and solutions by Hongxing technical:
1. Motor overheating and sound informality.
Reasons:
1) undesirable bearing lubrication or bearings badly worn;
2) fan leaves fall off or wore;
3) switching circuit badly contacted, or disconnected to run single-phase;
4) too low voltage.
2. Sound informality, cylinder stuck by obstacle, and even the cylinder cannot vibrate in operation.
The common reasons are objects in the bottom box are stuck, or magnets falling off cause tube skin scratched. At this time, maintenance and troubleshooting are necessary.
3. Reducer overheating:
1) insufficient fuel or bad oil;
2) over-wearing or bad engagement between gear and worm,;
3) undesirable bearing lubrication or bearings badly worn.
4. Magnetic field strength becomes weaker:
1) over- high temperature;
2) sun exposure;
3) acid corrosion. This can be measured by Gauss Meter.
