What is Ring High Gradient Magnetic Separators?
Vertical ring high gradient magnetic separator is a device that uses a
high-intensity magnetic field to separate magnetic materials through magnetic
field gradient. Unlike traditional low gradient magnetic separators, high
gradient magnetic separators can effectively separate fine-grained, weakly
magnetic, or weakly magnetic materials, with stronger sorting accuracy and
ability.
This type of equipment is commonly used in industries such as mineral
processing, environmental protection, metallurgy, and chemical engineering,
especially when dealing with materials containing fine magnetic impurities,
showing significant advantages.
1、 Working principle
The vertical ring high gradient magnetic separator uses a strong magnetic
field to adsorb magnetic substances under strong magnetic force, while weakly
magnetic substances are removed from the magnetic field. Its working principle
is mainly based on the following aspects:
High gradient magnetic field: The vertical ring high gradient magnetic
separator adopts a circular magnetic field design inside, utilizing the strength
gradient of the magnetic field in a local area to effectively capture small
magnetic particles in that area.
Core structure: The magnetic material inside the magnetic separator is
usually composed of multiple metal wires or cores, which can form a local high
gradient magnetic field and enhance the adsorption force of magnetic
particles.
Material sorting: When materials containing magnetic impurities pass through
the interior of the equipment, a strong magnetic field causes the magnetic
substance to be adsorbed on the surface of the magnetic medium, and then these
materials are separated from non-magnetic substances by means of reverse force
or vibration.
2、 Structural characteristics of vertical high gradient magnetic
separator
Circular structure design: Compared with traditional single magnet magnetic
separators, the magnetic field design of the vertical ring high gradient
magnetic separator is circular, forming a magnetic field area with high magnetic
field gradient, which can improve the capture efficiency of small particles.
Magnetic medium: The vertical ring high gradient magnetic separator uses
special magnetic media (such as stainless steel wire mesh or fine metal wire),
which can generate high magnetic field gradients, adsorb weak magnetic
particles, and achieve high separation accuracy.
High magnetic field strength: This device utilizes a high-intensity
electromagnetic field to generate a strong magnetic field, which can effectively
adsorb weak magnetic or tiny iron ore materials.
Adjustable magnetic field strength: The magnetic field strength of the
equipment is usually adjustable and can be optimized and adjusted according to
actual sorting needs.
3、 Application Fields
Vertical ring high gradient magnetic separators are widely used in the
following industries:
Mineral processing:
In the process of extracting mineral resources, the vertical ring high

the purity of chemical raw materials, and avoid affecting the quality of
subsequent products.
Especially in the process of catalyst recovery, the vertical ring high
gradient magnetic separator helps to recover tiny magnetic catalyst
particles.
environmental protection:
In the process of wastewater treatment or solid waste treatment, a vertical
ring high gradient magnetic separator can be used to remove ferromagnetic
pollutants from water.
Used for recycling tiny magnetic particles from waste materials to reduce
environmental pollution.
Power and electronics industry:
In the recycling of electronic waste, it is used to separate magnetic metals
and non-metallic substances from electronic waste.
Food industry:
Used for removing magnetic impurities in food processing to ensure product
quality and safety.
4、 Advantages of Vertical High Gradient Magnetic Separators
Efficient particle sorting capability:
Due to the design of high gradient magnetic fields, it is possible to sort
out magnetic substances with fine particle sizes, even weakly magnetic or
ultrafine magnetic particles can be effectively separated.
Strong adaptability:
This device has strong adaptability to changes in material particle size,
shape, and density, and can handle various types of ores or impurities.
Strong processing ability:
The equipment can handle high flow materials, and the magnetic separation
effect is stable with high separation accuracy.
Easy to operate and maintain:
The vertical ring high gradient magnetic separator has a simple structure,
relatively easy operation and maintenance, and is easy to adjust and replace
worn parts.
Environmentally friendly:
Through efficient magnetic separation, the discharge of wastewater, exhaust
gas, and solid waste can be effectively reduced, which contributes to
environmental protection.
5、 Precautions and Limitations
High energy consumption:
Due to the use of high-strength electromagnets inside the device, its energy
consumption is relatively high, especially when dealing with high flow
materials, which requires a large amount of electrical energy.
High maintenance requirements for equipment:
The metal medium part of the high gradient magnetic separator is prone to
wear and needs to be regularly inspected and replaced to ensure the magnetic
separation effect.
The impact of material properties:
The effectiveness of a magnetic separator depends on the magnetic properties,
particle size, shape, and other characteristics of the material. Different
materials may require adjusting the magnetic field strength or using different
media.
6、 Summary
The vertical ring high gradient magnetic separator is an efficient magnetic
material sorting equipment, which is widely used in industries such as mineral
processing, metallurgy, chemical engineering, and electronics due to its strong
sorting accuracy and processing capabilities. It utilizes the advantages of high
gradient magnetic fields in the sorting of small particles, making it
particularly suitable for the separation of weak magnetic and fine particulate
matter. Although the equipment has high energy consumption and requires regular
maintenance, its ability in fine sorting and high-purity material extraction
makes it an indispensable device in many industrial fields.
