LJWH Series super conducting magnetic separator for non-metallic minerals

Product overview

Superconducting magnetic separation is an innovative  physical magnetic separation method developed by applying
superconducting technology to the magnetic separation field.
lt is suitable for impurity removal and purification of non-metallic minerals,such as kaolin,bauxite,redmud,epidolite
andotherminerals.

Equipment principle

Superconducting wires made of Nb-Ti alloy and other superconducting
materials are wound into special coils and placed in a well-sealed
low-temperature dewar.By adopting liquid helium immersion cooling or
conduction cooling,the operating temperature of the superconducting coilis is maintained at approximately-268.8℃C.

At this temperature,the superconducting Coil has zero electrical resistance
and enters the superconducting state.It can carry a large curent without
generating heat, thereby producing a high background magnetic field of over 2T. The GM refrigerator(rated power:7.5 kW)only needs to keep the superconducting magnet in such a low-temperature condition.Compared with
conventional resistive magnets, it saves more than 90% of power
consumption, thoroughly solving the high energy consumption problem of conventional magnetic separation operations.

Technical features

• Magnetic Field Intensity

The high magnetic field can reach above 5T, 3 to 5 times that ofconventional magnetic separators.

• Operating Cost
  

Excitation power consumption<15kW/h. Compared with traditionalmagnetic separators, the energy saving rate exceeds 90%.

• High Degree of Automation

Equipped with PLC automatic control and equipment conditionmonitoring functions to ensure long-term and reliable operation,realizing unattended operation.

• High Separation Precision

It can capture fine weakly magnetic particles smaller than 30 umthat cannot be recovered by conventional magnetic separators. Itimproves the enrichment ratio of magnetic materials, reduceschemical reagent consumption and tailings discharge, andenhances resource utilization efficiency.

• Low Maintenance Cost

The maintenance cycle of helium refrigerant is 10,000 hours; theservice/maintenance cycle of helium compressors and watercooling units is 25,000 hours.
