LHGC Advantages Over Traditional Vertical Ring WHIMS
| Traditional vertical ring WHlMS concems | 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 | Ultrasonic liquid level detection is adopted, which is linked with the electric actuator to automatically adjust the separation liquid level. |
| Manual lubrication, low safety level | Idle gear automatic lubrication, safe and reliable |
| Manual operation and maintenance, labor-intensive | Intelligent control, unattended operation |
The LHGC oil-water cooling vertical ring high gradient magnetic separator(WHlMS)utilizes the combination of magnetic force, pulsating fluid and gravity to continuously separate magnetic and non magnetic minerals. It possesses the advantages of large processing capacity, high beneficiation efficiency and recovery rate, small thermal attenuation of magnetic field, thorough discharge, and high degree of intelligence.
The LHGC vertical ring high gradient magnetic separator (WHlMS)is reliable and easy to operate and maintain, and the Internet of Things and Cloud Platform Technology has been applied to realize intelligent automatic operation, To compare with the traditional WHIMS, LHGC adopts a number of new technologies and processes, which effectively improves the operation efficiency, separation accuracy and tailing discard rate, as well as lower maintenance and operating costs.
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 fiow into the non-magnetic material collection hopper along the slots in the lower magnetic pole to be discharged.

Technical Parameters And Main Performance Indicators
Model selection method: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.
