LCGC 5T/300 Vertical Superconducting High Gradient Magnetic Separator
The LCGC 5T/300 Vertical Superconducting High-Gradient Magnetic Separator is a high-intensity magnetic separation system designed for the efficient separation and purification of weakly magnetic and fine-grained materials.
Using a superconducting magnet system with a background magnetic field of up to 5 T, the separator generates an extremely strong magnetic field and high magnetic field gradient when combined with high-gradient magnetic media. This enables the effective capture of fine and weakly magnetic impurities that are difficult to remove with conventional magnetic separation equipment.
The vertical configuration provides a large separation space and supports efficient, continuous operation. The system is designed for demanding mineral processing and purification applications, including non-metallic mineral purification, fine particle separation and high-value material upgrading.
With a closed cryogenic system and zero liquid-helium evaporation during normal operation, the LCGC 5T/300 is designed to reduce helium consumption, maintenance requirements and long-term operating costs.
Key Features
1.Up to 5 T High Magnetic Field
The LCGC 5T/300 provides a continuously adjustable background magnetic field of 0–5 T. The high magnetic field, combined with high-gradient magnetic media, generates strong magnetic forces for capturing fine and weakly magnetic particles.
This high-field configuration is particularly suitable for the removal of weakly magnetic impurities from high-value mineral materials.
2.High-Gradient Magnetic Separation
The combination of a superconducting magnet and high-gradient magnetic media creates a strong magnetic field gradient within the separation zone.
The system can effectively capture fine weakly magnetic particles and improve the purification and upgrading performance of mineral materials.
3.Zero Liquid Helium Evaporation
The superconducting magnet adopts a closed cryogenic system with a low-temperature refrigeration system and thermal insulation structure.
The system is designed to achieve zero liquid-helium evaporation and zero routine helium replenishment, reducing the operating and maintenance requirements associated with conventional superconducting magnetic separation equipment.
4.Vertical Separation Structure
The vertical configuration provides a large effective separation space and a deeper separation zone.
The design supports efficient material flow and helps reduce blockage risks associated with fine separation media, while enabling continuous separation and cleaning operation.
5.Continuous and Stable Operation
The LCGC 5T/300 is designed for continuous operation and incorporates intelligent monitoring and control functions.
Key operating parameters such as magnetic field intensity, temperature, flow rate and liquid level can be monitored through the control system, supporting stable operation and efficient process management.
Technical Innovations
1.High-Field and High-Stability Superconducting Magnet
The superconducting magnet is developed using multi-physics coupled design and simulation technology.
Electromagnetic, thermal and structural parameters are jointly considered to optimize the magnetic field distribution, temperature variation and structural reliability of the superconducting magnet.
The system is designed to achieve a stable magnetic field of up to 5 T while maintaining the required low-temperature operating conditions.
2.Closed Cryogenic System
The cryogenic system uses a high-vacuum thermal insulation and radiation-shielding structure to reduce heat leakage.
A refrigeration and helium circulation system is integrated into the superconducting magnet system to support long-term operation with zero liquid-helium evaporation under normal operating conditions.
This design helps eliminate the need for frequent helium replenishment and reduces routine maintenance requirements.
3.High-Gradient Magnetic Separation
The high magnetic field generated by the superconducting magnet is combined with high-gradient magnetic media to create a strong magnetic field gradient.
Weakly magnetic fine particles can therefore be captured more effectively, making the equipment suitable for difficult purification and separation applications.
4.Vertical Configuration for Efficient Separation
The vertical structure makes full use of the axial space of the superconducting magnet and provides a large effective separation volume.
The configuration is designed to improve separation efficiency while supporting continuous feeding, separation and cleaning processes.
Working Principle
The LCGC 5T/300 operates based on the principle of superconducting high-gradient magnetic separation (S-HGMS).
When the superconducting magnet is energized, it generates a high-intensity magnetic field within the separation zone. High-gradient magnetic media are placed in the magnetic field to create localized regions with a strong magnetic field gradient.
When the feed material enters the separation zone, weakly magnetic particles are attracted to the magnetic media under the influence of magnetic force, while non-magnetic particles pass through the separation zone.
During the cleaning stage, the captured magnetic particles are released from the magnetic media and discharged from the separation system.
The combination of a high magnetic field, high magnetic field gradient and suitable magnetic media enables efficient separation of fine weakly magnetic particles from valuable non-magnetic materials.
Applications
The LCGC 5T/300 is suitable for the separation and purification of fine-grained and weakly magnetic materials, particularly high-value mineral materials requiring high-purity processing.
