Equipment introduction
Superconducting magnetic separation is an innovative physical magnetic separation method developed based on the application of superconducting technologies in the field of magnetic separation. It is suitable for removing impurities and purifying non-metallic minerals such as kaolin, bauxite, red mud, epidolite and other minerals.
Description of equipment
Superconducting wires made of Nb-Ti alloy and other superconducting materials are wound into special coils and placed in a sealed low-temperature Dewar vessel. Through liquid helium immersion cooling or conduction cooling, the operating temperature of the superconducting coils is maintained at approximately -268.8 °C.
At this temperature, the superconducting coil has zero electrical resistance and goes into a superconducting state. It can conduct large currents without generating heat, thereby creating a strong background magnetic field with an induction of more than 2 Tesla. The GM refrigerator (rated power: 7.5 kW) is only needed to maintain the superconducting magnet in this low temperature state. Compared with conventional resistive magnets, it saves more than 90% energy consumption, completely solving the problem of high energy consumption in traditional magnetic separation operations.
Specifications
Magnetic field strength
The magnetic field strength can reach 5 Tesla or more, which is 3–5 times higher than that of conventional magnetic separators.
· Operating costs
The power consumption of the excitation system is less than 15 kWh. Compared to traditional magnetic separators, energy savings exceed 90%.
· High degree of automation
The equipment is equipped with a PLC-based automatic control system and a condition monitoring function, which ensures long-term stable operation and allows operation in automatic mode.
High separation accuracy
Capable of capturing fine, weakly magnetic particles less than 30 microns in size, which cannot be removed by conventional magnetic separators. This increases the enrichment ratio of magnetic materials, reduces the consumption of chemical reagents and the volume of waste, thereby increasing the efficiency of resource use.
Low maintenance costs
The maintenance period for helium-based refrigerant is 10,000 hours; The maintenance period for the helium compressor and water cooling system is 25,000 hours.
