Recently, I often have friends leave a message asking about the purchase of magnetic separator attention, first of all thank you for the trust of my friends, there is no report, now sum up the following points for your reference:
1. China's high-gradient magnetic separator is divided into two groups: north and south, namely, aluminum coils and copper coils. Water-cooled or air-cooled is actually water-cooled. Before the water cooling was direct cooling, it was easy to produce scale, and later used oil to cool, but the oil temperature will rise, so later design water to reduce the oil temperature, but if the oil temperature is too high, the heat exchanger can also produce scale, which This is the reason why oil-water composite cooling heat exchangers are often bad. The aluminum coil voltage has high current and low current. The current is generally below 200A. The copper coil is low voltage and high current, and the current is more than 1000A.
2. No matter how high the manufacturer's publicity magnetism, manufacturers must be required to remove the swivel measurement, the magnetic meter is only 900 yuan a 3. Magnetic power like to see the energy, the more power the device shows that the better the device, with 2 meters vertical ring machine For example, the power consumption is less than 70kw, and there is a problem if the device is higher than 100kw. The power calculation is based on DC voltage * DC current.
4. Copper coils are more resistant to overload but have more power consumption. The holes in the copper tubes are easy to block. The aluminum coils can increase the voltage and save power. The magnetic force can also be less than 16,000. 5. Simply speaking, the electromagnetic separator is a large one. DC electromagnet, industrial power 380V direct rectification 514V DC Since the 2015 domestic market there are few copper coils, high cost is the most important factor, the coil energy consumption is also a reason 6. Aluminum coils have oil cooling and water cooling two In fact, oil cooling is also used to cool oil in water. It is also water-cooled. Water-cooled coil manufacturers are equipped with safety transformers. 7. Buy equipment must see whether the operation condition of the rotating ring is stable, good equipment conversion operation is very smooth, and poor equipment conversion. Easy to operate. Generally, the equipment in the north is used more frequently because the north is cold in the winter, and it is easy to freeze. In some manufacturers, the operator is not standardized. When the machine is stopped, the cooling water is not blown out with compressed air, causing the coils to freeze and crack. Generally, the maintenance rate of the work equipment is higher after the year. 8. When the normal production is stopped, the cooling water must be kept on for more than 15 minutes after the coil is stopped to avoid damage to the coil caused by the coil heat dissipation.
We must bear in mind that no matter which manufacturer buys the magnetic separation equipment, it is required to remove the rotating ring before leaving the factory, leaving only the electromagnets and coils. The manufacturer is required to measure the space magnetic field. If it can reach 13,000 GS, the equipment can run almost without any problems. Rest assured 9. When the equipment is pulled back to the factory to test the stage, pay attention to the heat of the cooling water outlet of the coil of the equipment. The material used for the high water temperature coil is less. We must remember that the normal water temperature does not exceed 50 degrees.
The above points are personal summaries for everyone to learn from each other, and hope to help customers and friends who have needs.
