Vertical High Gradient Magnetic Separator
1. Overview
The vertical high gradient magnetic separator is an advanced and innovative magnetic separation device. It is designed to address the challenges associated with separating weakly magnetic minerals and has been widely adopted in the mining and mineral processing industries. This type of separator represents a significant technological leap, offering improved efficiency and performance compared to traditional magnetic separation equipment.
2. Working Principle
The working mechanism of the vertical high gradient magnetic separator is based on the principle of magnetic attraction. The separator consists of a magnetic yoke fixed on the machine frame, which, together with the exciting coil, generates a strong magnetic field. The rotary ring, driven by a rotary device in a clockwise direction, slowly passes through this magnetic field. There are numerous separation boxes on the outer circle of the rotary ring, each containing multi - layer magnetic media made of magnetic materials.
When the rotary ring enters the magnetic field, it becomes magnetized, forming a high gradient magnetic field. During mineral processing, the mine slurry enters the rotary ring through the gap between the magnetic poles. Magnetic particles in the slurry are attracted to the surface of the magnetic media. As the ring rotates to the non - magnetic area, the magnetic particles are directed into the concentrate tank, while non - magnetic materials flow into the tailing tank through the lower magnetic yoke gap.

3. Features
3.1 Solving the Blocking Problem
One of the most remarkable features of the vertical high gradient magnetic separator is its ability to overcome the problem of magnetic medium blockage. In contrast to the flat ring rotary pattern, the vertical ring's moving direction is opposite to the concentrate ore discharging direction. This design ensures that large - particle - sized materials do not block the gaps in the magnetic medium. Instead, they are directed into the tailing tank, effectively solving the long - standing issue of high - gradient magnetic separation blockage.
3.2 High - Frequency Vibration Mechanism
The separator is equipped with a high - frequency vibration mechanism for the ore slurry. This mechanism generates a pulsating fluid force in the ore slurry. Under the action of this force, the ore particles in the slurry are always in a loose state. This not only helps prevent the aggregation of particles but also improves the quality of the magnetic concentrate.
3.3 Wide Adaptability to Feed Particle Size
Thanks to its unique magnetic system structure and optimized combination of magnetic media, the vertical high gradient magnetic separator can handle feed with a particle size of up to 2.0 millimeters. This wide adaptability simplifies the on - site classification process, making the separator suitable for a broader range of applications compared to traditional magnetic separators.
3.4 High Magnetic Force and Reliable Performance
The induction field strength can reach 20000GS, This high magnetic force ensures the effective separation of weakly magnetic minerals. Additionally, the separator offers reliable performance, with stable operation and low maintenance requirements.
3.5 Intelligent Operation Control
Modern vertical high gradient magnetic separators are equipped with intelligent control systems. These systems can adjust operating parameters such as the rotation speed of the rotary ring and the vibration frequency of the high - frequency vibration box according to the characteristics of the ore slurry. This intelligent operation control not only improves the separation efficiency but also reduces energy consumption.
4. Application Scope
4.1 Black Metal Separation
It is widely used in the recovery of black metal minerals such as hematite, limonite, siderite, chromite, and manganese ore. For example, in the beneficiation of hematite - rich ores, the vertical high gradient magnetic separator can effectively separate hematite from gangue minerals, improving the iron ore grade.
4.2 Non - ferrous Metal Separation
In the non - ferrous metal industry, it is used for tasks such as the separation of fine - grained wolframite in tungsten - bearing quartz veins, the separation of pyrrhotite in cassiterite polymetallic sulfide ores, and the separation of cassiterite and wolframite. It helps to improve the recovery rate of valuable non - ferrous metal minerals.
4.3 Rare Metal Recovery
For rare metal minerals like tantalum - niobium iron ore, lepidolite, and monazite, the vertical high gradient magnetic separator plays a crucial role in their recovery. It can effectively separate these rare metal - bearing minerals from the ore matrix, contributing to the efficient utilization of rare metal resources.
4.4 Non - metallic Mineral Purification
In the field of non - metallic minerals, the separator is used for the purification of materials such as quartz, feldspar, kaolin, and refractory materials. It can remove iron - containing impurities from these non - metallic minerals, improving their quality and meeting the requirements of industries such as glass, ceramics, and refractory materials.
4.5 Other Applications
It is also used in weak magnetic tailings recovery, iron separation from red mud in alumina plants, wastewater treatment in steel and power plants, and the cleaning of chemical raw materials contaminated by catalysts.
