LHGC Advantages Over Traditional Vertical Ring WHIMS

The LHGC oil-water cooling vertical ring high gradient magnetic separator (WHIMS) 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 (WHIMS) 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.

Technical Features

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。

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.

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

Automatic Cyclone Sedimentation Filtration System

The filter adopts the cyclone sedimentation structure, and the sedimentation speed is fast. According to the cleanliness of the flushing water,the automatic impurity discharge cycle is set, and the filter system is always kept unblocked to ensure that the small holes of the flushing water are not blocked.

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

Liquid Level Automatic Control System

The liquid level fluctuation state of the separation chamber is detected in real time 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.

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.

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.

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..

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

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.
