Technical Features
1. Oil-water Heat Exchange Cooling Technology
The coil adopts large-flow external circulation oil-water heat exchange for heat dissipation. The coil temperature rise is less than 25°C, the magnetic field heat attenuation is small, and the mineral processing index is stable. The coil adopts a fully sealed structure, which is rain-proof, dust-proof and corrosion-resistant, which can adapt to various harsh working environments.
2. Precise Magnetic Circuit Design
Using finite element simulation optimization, the magnetic circuit design is reasonable, the magnetic energy loss is small, and the magnetic field strength can reach 0.6T, 0.8T, 1.0T, 1.3T, 1.5T, 1.8T
3. Long-life Integrated Magnetic Matrix
The matrix adopts an one-piece through-type structure, and the medium rods do not fall off; the fixing lug plate adopts a conical structure design, and the connection strength is high; it is welded with special robot equipment, with reliable quality and strong interchangeability.
4. Flushing Water Mineral Discharge System
The pressure of the flushing water is detected in real time, so that the flushing water maintains sufficient pressure and flow, and the minerals in the matrix are discharged thoroughly.
5. Liquid Level Automatic Control System
The liquid level fluctuation state of the separation chamber is detected in realtime by the ultrasonic sensor, and it is linked with the electric actuator, so that the liquid level of the separation chamber always maintains at the best separation state; manual operation is reduced, and the difficulty of manual inspection is lowered; excessive amount of instantaneous slurry is prevented to avoid overflow.
6. Temperature Alarm Protection System
Coil temperature sensors are provided to detect the working temperature of the coil in real time and feed back the information to the control center. When the coil temperature exceeds the set value, the system will automatically alarm, and the equipment will stop working when the upper limit is reached to ensure the safe operation of the equipment.
7. Leakage Alarm Device
The cooler adopts a double-layer tube-plate structure, and there is a leakage detection device between the layers. When leakage occurs, the equipment will automatically alarm and stop, so as to avoid the damage to the coil caused by the ingoing water in the cooling oil.
8. Automatic Lubrication System
The ring drive gear adopts an idle gear automatic lubricating device to ensure that the equipment can realize automatic quantitative lubrication without stopping the operation and improve the operation rate..
9. Remote Intelligent Service Platform Based on Internet of Things Technology
The Internet of Things and cloud platform technologies are applied to collect and analyze equipment operation data in real time to realize remote operation and maintenance, fault diagnosis and full life cycle management of equipment.
Operating Principle
The slurry is introduced to the feeding hopper through the feeding pipe, and enters the magnetic matrix on the rotating ring along the slots in the upper magnetic pole. The magnetic matrix is magnetized, and a high gradient magnetic field is generated on its surface. The magnetic particles are attracted on the surface of the magnetic matrix, and are brought to the
non-magnetic area at the top with the rotation of the ring, and then are flushed into the collection hopper by pressure water flushing. The non-magnetic particles flow into the non-magnetic material collection hopper along the slots in the lower magnetic pole to be discharged.
Applications
It is suitable for wet concentration of various weakly magnetic metallic ores such as hematite, limonite, specularite, manganese ore, ilmenite, chrome ore, rare earth ore, etc., as well as for iron removal and purification of non-metallic minerals such as quartz, feldspar and kaolin.

LHGC Advantages Over Traditional Vertical Ring WHIMS
| Traditional vertical ring WHIMS concerns | LHGC Solutions |
| The coil adopts hollow wire and water cooling method. The inner wall of the wire is easy to form lime scale, and it must be acid cleaned regularly, the failure rate is high, and the coil life is short. | The coil is immersed in oil for cooling, and adopts forced large-flow external circulation, which has fast heat dissipation, low temperature rise and is maintenance-free. The coil shell adopts a fully sealed structure, which is more suitable for more harsh environments. |
| The rod matrix falls off easily | The matrix adopts a one-piece through-type structure, and the medium rods do not fall off; the fixing lug plate adopts a conical structure design, which has high connection strength and is not easy to break. |
| Slurry overflow | |
| Manual lubrication, low safety level | Idle gear automatic lubrication, safe and reliable |
| Manual operation and maintenance,labor-intensive | Intelligent control, unattended operation |

（1.3T/1.5T/1.8T）Major technical parameters:（ non-metallic minerals）
In principle,the model selection of equipment is subject to the amount of mineral slurry.when separating minerals using
this kind of equipment, the slurry concentration has certain influence on the mineral processing index.To get better mineral processing index,please reduce the slurry concentration properly. If the ratio of the magnetic materials in the mineral feed is slightly high, the processing capacity will be limited to the total catching amount of magnetic minerals by magnetic
matrix, in the case, the feed concentration should be reduced appropriately.
