We were established as the most specialized mineral processing equipment company since 1985.
The wet drum magnetic separator is an environmentally friendly magnetic separation device developed to address the challenge of separating fine-grained, weakly magnetic minerals. It integrates an innovative design combining “weak magnetic drum iron removal + strong magnetic roller separation,” providing a stable and deep magnetic field that ensures superior adsorption capacity for fine-grained minerals. It is primarily suitable for wet separation of magnetic minerals such as magnetite, manganese ore, and ilmenite with a particle size of less than 3mm. It also undertakes purification operations in non-metallic minerals, building materials, and ceramics industries, removing magnetic impurities to meet the high-purity requirements of the glass and photovoltaic industries.
Wet drum magnetic separators, also known as permanent magnet drum high-intensity magnetic separators. Its core function is to attract magnetic particles using a strong magnetic field generated by an internal magnetic system, thereby improving material purity or recovering valuable resources. The magnetic system is often made of ferrite materials or rare earth magnets (such as neodymium iron boron), offering high separation efficiency and strong adaptability. They are widely used for the rapid separation of metallic materials with a particle size of less than 3mm, such as iron ore, manganese ore, magnetite, tantalum-niobium, tin, ilmenite, and coltan, improving iron grade and reducing the content of harmful impurities such as silica, sulfur, and phosphorus. In the non-metallic mineral field, their core application is the removal of iron impurities from materials such as kaolin, quartz sand, feldspar, zircon sand, and silica sand, improving product whiteness and purity. The drum magnetic separator’s fully wet operation virtually eliminates dust pollution, meeting modern environmental requirements for environmentally friendly mineral processing. 24-hour automated operation achieves a separation efficiency of over 95% for fine-particle minerals.
Furthermore, the wet drum magnetic separator is compatible with three types of troughs: co-current, counter-current, and semi-counter-current, which can be flexibly adjusted according to material characteristics to meet the needs of different sorting scenarios. The co-current type is suitable for roughing, the counter-current type is ideal for scavenging, while the semi-counter-current type balances recovery rate and concentrate grade.
Magnetic System
Made of ferrite or rare earth magnet composite, with a uniform and stable magnetic field and strong adsorption force.
Rotating Drum:
The outer shell of the cylinder is made of 304 stainless steel plate and the surface is covered with wear-resistant rubber. It is a metal cylinder that serves as a carrier for adsorbing magnetic clusters.
Tank:
There are three types: co-current, counter-current, and semi-counter-current. The material is wear-resistant rubber or stainless steel. It guides the flow of slurry and is adapted to different material characteristics.
Frame:
Welded from structural steel to support the weight of the equipment, with adjusting bolts at the bottom for easy installation and leveling.
Transmission System
It consists of a motor, reducer, pulleys, and chain, which drives the cylinder to rotate.

The core principle of a wet drum magnetic separator is to separate minerals based on differences in their magnetic properties. The specific process includes feeding, magnetic separation, magnetic mineral adsorption, washing and unloading, and separation of concentrate and tailings. The slurry enters the separation tank evenly from the feed box. Magnetic particles are magnetized in the magnetic field and adsorbed onto the drum surface, rotating with the drum to the concentrate discharge area. Non-magnetic minerals are unaffected by the magnetic field and, under the influence of water scouring and gravity, fall directly into the tailings trough for discharge.

They are mainly used for separating magnetic minerals such as magnetite, hematite, manganese ore, and ilmenite. They can also be used for iron removal from non-metallic minerals such as quartz sand and kaolin.
Co-current is suitable for 0-6mm coarse-grained materials; semi-counter-current is suitable for 0-3mm fine-grained strongly magnetic materials; counter-current is suitable for those seeking the highest concentrate grade.
Wet magnetic separators use a slurry (water + minerals) as the medium and are suitable for separating fine-particle minerals. Dry magnetic separators are suitable for dry powders, producing more dust but requiring no water circulation system.
Factors to consider:
(1) Mineral type (strong, weak magnetic, particle size): determines magnetic field strength
(2) Processing capacity (tons/hour): determines equipment size
(3) Budget: large price difference between permanent magnet and electromagnetic
(4) Automation requirements: whether PLC control is required
It is recommended to provide a small sample for testing to customize the best solution.
● Strongly magnetic minerals: Magnetite concentrate grade increased by 10-30%, recovery rate ≥90%.
● Weakly magnetic minerals: Ilmenite and manganese ore recovery rate 85%+.
● Non-metallic minerals: Quartz sand/feldspar iron removal rate 95%+.
Note: Specific grades and recovery rates will be verified based on the characteristics of your raw ore. JXSC also provides mineral testing services.
