Manual Suspended Magnet
The Manual Suspended Magnetic Separator (also known as the “Plate-Type Manual Iron-Discharging Permanent Magnetic Separator”) belongs to the category of permanent magnetic separators with the simplest structure, lowest price, and smallest footprint. It is easy to manufacture, install, and maintain. Based on configuration, it can be divided into suspended-fixed type and bottom-fixed type. among which the suspended-fixed plate-type separator is suitable for installation above belt conveyors.
Applicable Industries
With the improved performance of permanent magnetic separators, they have been widely applied in industries such as mining, coal preparation, metallurgy, power plants, ceramics, cement, building materials, chemicals, and food processing.
Typical Working Conditions
Dimension Specific Requirements
Installation Position Above the belt conveyor (suspended type) or below the discharge hopper/chute (bottom-fixed type)
Iron Content Suitable for applications with small and few iron impurities
Material Thickness Material flow thickness preferably not exceeding 100 mm
Belt Width Mostly used for belt conveyors with width below 1400 mm
Magnetic Field Strength Rated suspension height magnetic field strength below 900 Gs (for safety, automatic iron discharge, transport, and maintenance considerations)
Adsorption Capacity Capable of attracting ferromagnetic impurities weighing 0.1–25 kg
Reference Specifications
Taking the RCYB series suspended permanent magnetic separator as an example, the specifications range from RCYB-4 to RCYB-16, accommodating belt widths from 400 mm to 1600 mm, with suspension heights of 75–450 mm and material thicknesses of 30–400 mm.
III. Product Features
Key Advantages
- Simple and Compact Structure: The simplest among all magnetic separators, easy to manufacture, install, and maintain;
- Low Cost: The lowest price among all types of magnetic separators[1];
- Small Footprint: Compact equipment with low site layout requirements;
- Strong Magnetic Force and Stable Performance: Uses high-performance NdFeB permanent magnets, ensuring stable operation and low energy consumption;
- Lightweight, Easy to Operate and Maintain;
- High Safety During Power Failure: In the event of a sudden power outage, the iron objects already attracted will not fall back into the raw materials;
- Reliable Operation: The strong and stable magnetic field generated by permanent magnets ensures effective adsorption of ferromagnetic impurities.
Limitations (Drawbacks to Note)
- Magnetic field strength cannot be adjusted;
- Inconvenient for transport and installation; large attracted iron pieces are difficult to remove;
- Continuous high-frequency vibration may cause changes in the magnetic structure, leading to magnetic force attenuation;
- High-temperature environments may cause demagnetization;
- Requires periodic manual iron discharge, which is labor-intensive — trapped iron objects are directly attracted to the magnetic plate and must be removed manually using non-magnetic scrapers or by hand with gloves;
- Not suitable for applications with large iron content: Only suitable for conditions with small and few iron impurities.
| Application Scenario | Recommendation | Reason |
|---|---|---|
| Small production lines, low iron content | Highly Recommended | Best cost-performance ratio, simple and reliable structure |
| Belt width ≤ 1400 mm | Recommended | Fully matches the design range |
| Material layer thickness ≤ 100 mm | Recommended | Within the effective design range |
| No frequent shutdown allowed | Use with Caution | Manual iron discharge requires shutdown, affecting continuous production |
| High temperature, strong vibration | Not Recommended | Risk of demagnetization and magnetic attenuation |
| High iron content / large iron pieces | Not Recommended | Difficult to remove large iron pieces; self-discharging or electromagnetic types should be chosen |
Conclusion
The Manual Suspended Magnetic Separator, with its core advantages of simple structure, low price, small footprint, and easy installation and maintenance[1], has become the preferred iron removal solution for small-to-medium conveying lines with low iron content and thin material layers. However, its limitations of non-adjustable magnetic field, manual iron discharge requirement, and unsuitability for high-temperature/strong-vibration environments[1] mean that it is more suitable as an auxiliary or protective iron removal device. For applications with higher iron content, upgrading to a self-discharging belt-type permanent magnetic separator or an electromagnetic separator is recommended to improve production efficiency and safety.
