Series RCSC Superconducting Iron Separator
Application
RCSC series low-temperature superconducting magnetic separator uses superconducting magnets to generate a strong magnetic field required for iron removal. The advantage is that in the superconducting state (-268.8°C), there is current without resistance, and the current passes through the superconducting coil to generate a super-strong magnetic field. High magnetic field strength, large magnetic field depth, strong iron absorption ability, light weight, low energy consumption, energy saving and environmental protection, etc., the advantages that ordinary electromagnetic separators cannot match. It is mainly used to remove fine iron impurities contained in the coal seam.

◆ Special design of the electromagnetic coils.
◆ Oil & water compound cooling way with high efficiency
◆ High gradient at the nodes of the magnetic media with better performance
◆ Low energy consumption, completely automatic operation, low costs of operation and maintenance
◆ The brake valve is durable and the switch is smooth
◆ Assisted with vibration motor and high pressure water rinsing, it can remove the ferrous impurities effectively without residue.
◆ The magnetic media adopt the high efficient and inductive stainless steel, which has no residue magnetic power after power-off, and can remove the impurities easily.

Advantages:
Low Cost
The superconducting magnet of the superconducting magnetic separator adopts vacuum grease impregnation technology, which shortens the production time and reduces the production cost;
- Adopts liquid helium immersion cooling, negative pressure operation, zero volatilization, saving the cost of liquid helium, and improving the stability of the magnet operation.
- Light weight, total mass about 8 tons, easier to install.
Low Operation Costs
The cold head is easy to maintain. Other companies’ products must be rewarming for cold head maintenance, which takes about 15 days; while our company’s products can directly replace the cold head in a cold state, and the replacement time is only 1 hour, which can greatly save time, contribute to continuous iron separation and improve production efficiency.
Less loss of liquid helium when replacing the cold head. Replacement of cold head for other companies’ products requires rewarming. After all the liquid helium in the magnet volatilizes, replace the cold head, and then fill it with liquid helium again to work normally;
However, our products can be replaced in a cold state, only a small amount of liquid helium volatilizes, and can work normally without supplementing liquid helium.
Low Maintenance Costs
Easy to operate. It adopts Chinese and English interface, desktop computer control or touch screen computer control, which is easy to understand and operate.
Remote monitoring. Multiple cameras are installed on site to monitor the operation status of the superconducting magnetic separator, and the on-site operation of the magnetic separator can be monitored remotely through the network. Its operating parameters are transmitted to the remote terminal through the network. By analyzing the operating parameters, the technicians can find out the possible problems of the superconducting magnetic separator in advance, and direct the on-site personnel to deal with them in advance or make a plan in advance to reduce the occurrence of failures.
Working Principle
01
The low-temperature superconducting magnetic separator is mainly composed of the shell and the hanging device, the superconducting magnet part, the refrigeration system and the automatic control system. The superconducting magnet is hung on the shell, and the refrigeration system is used to maintain the temperature of the liquid helium.
02
Due to the extremely high magnetic field intensity generated by the low-temperature superconducting magnetic separator, the huge magnetic field force will cause iron debris to impact the magnet at a very fast speed, which may cause damage to the superconducting magnet. Therefore, the superconducting magnet of the low-temperature superconducting magnetic separator is suspended on the shell through the Suspension Device. The shell is equipped with a national patented product - a flexible hanging device. When iron debris violently impacts the magnet, this device can reliably absorb the impact energy, protect the superconducting magnet from damage, and ensure that the low-temperature superconducting magnetic separator can work well for a long time.
03
The operation control part of the low-temperature superconducting magnetic separator adopts Chinese and English working interfaces, which is easy to understand, easy to use, easy to maintain, and can realize online transmission of operation records and online monitoring of operation status, realizing remote control and diagnosis,improve the reliability of equipment operation.
