Coils
Special design of exciting coil, there are the gaps among the winding coils which supply the cooling oil conduit. Increase the scatter area and oil-cooling conduit. Quick heat exchanging. Coil temperature rise is no more than 30 ℃, low temperature rising in cold and hot state, magnetic field difference is small, compare with the same magnetic field strength, the excitation power reduction 20%, saving electricity 45000 KWh/ year.
Fully sealed structure, dust proof, moisture proof, high temperature resistant, it can operate in harsh environment.

Cooling system
1. Cooling system adopts fully sealed outer circulating structure, rain-proof, dust-proof, anticorrosion, suits for all kinds of harsh environment.
2. Adopt air cooling condenser, intelligent control, excitation coil temperature is constant, magnetic field fluctuation minimum (less than 2%)of cooling mode, other domestic manufacturers makes coil temperature is too high, magnetic field fluctuation reach15%～30%, which have great influence to ore dressing indexes.
3. With large flow disc transformer oil pump, fast circulation speed, quick heat exchange.
Cooling system diagram
Forced oil cooling system includes winding coil, oil-inlet tube, return line, condenser, oil circulation pump, flow meter, flow valve, thermocouple, make-up oil tank, respirator, etc.
Selection methods: usually we choose the equipment based on the capacity of concentrator.
Note: the red data means meduim intensity high gradient magnetic separator.
