Wet magnetic separators are essential industrial tools for recovering valuable magnetic metals from slurry and incineration bottom ash (IBA). Designed for precision and efficiency, they play a key role in mineral processing and waste resource recovery, ensuring high-purity concentrates while protecting downstream equipment.
Working Principle of Wet Magnetic Separator
How Does A Wet Magnetic Separator Work? The working principle of the Wet Magnetic Separator is that, when slurry or incineration bottom ash (IBA) enters the magnetic field area, strong magnetic minerals are adsorbed onto the rotating cylinder surface. Weak magnetic and non-magnetic minerals are rejected and discharged as tailings.
The captured strong magnetic minerals rotate with the cylinder, exit the magnetic field zone, and are washed into the concentrate tank by flushing water, completing the separation of magnetic particles.
Dry Magnetic Separator and Wet Drum Magnetic Separator
Magnetic separators are engineered specifically for separating magnetic minerals, with iron ore being the most common application. They are divided into two primary categories, each optimized for different process stages:
- Dry Drum Magnetic Separator: Operates on dry, crushed ore, primarily used in pre-casting or pre-concentration processes. It is ideal for scenarios where water is scarce or where dry processing is required, effectively removing bulk gangue before further grinding.
- Wet Drum Magnetic Separator: Designed for slurry-based processing, it is mainly used after grinding and other wet beneficiation steps. By working in a water medium, it achieves higher separation precision and cleaner concentrates, making it suitable for fine-grained ores and incineration ash recovery.
Types of Wet Magnetic Separators by Flow Direction
Guangxi Ruijie Slag Equipment Manufacturing Co., Ltd. specializes in wet magnetic separators tailored for screening magnetic metals in magnetite, pyrrhotite, ilmenite, and incineration bottom ash (IBA) with particle sizes below 3mm.
Based on the flow direction of slurry or IBA, our wet magnetic separators are classified into three types:
- Downstream Wet Magnetic Separator: Material flows in the same direction as the cylinder rotation, ideal for coarse particles and high-capacity rough separation.
- Countercurrent Wet Magnetic Separator: Material flows opposite to the cylinder rotation, delivering higher concentrate grade and recovery for fine-grained materials.
- Semi-countercurrent Wet Magnetic Separator: Combines the advantages of both, balancing capacity and precision, making it the most versatile option for most mineral processing scenarios.
All three designs effectively improve the recovery rate of concentrate powder and magnetic metal particles, adapting to diverse on-site process requirements.
