Introduction
The YTO CTB series wet permanent magnetic drum separators are industry-leading magnetic separation equipment specifically engineered for efficient separation of ferromagnetic and paramagnetic minerals from slurry in mineral processing plants. Featuring advanced NdFeB rare earth magnetic systems and semi-countercurrent tank designs, these heavy-duty magnetic separators deliver exceptional mineral recovery rates (up to 99%) while maintaining extremely low operating costs. As the core equipment in iron ore beneficiation lines, YTO magnetic separators are also widely used for coal purification, non-metallic mineral de-ironing and tailings recovery applications worldwide.
Core Advantages
✅Premium Rare Earth Magnetic System
- Adopts high-performance NdFeB permanent magnets with high magnetic energy product and coercivity, providing magnetic field strength up to 18000 Gauss. 8-year demagnetization rate does not exceed 5%, ensuring long-term stable performance.
✅ High Recovery & Grade Optimization
- Large-envelope magnetic system with gradual field strength distribution and multiple magnetic flips effectively captures fine and ultra-fine magnetic particles, achieving both high concentrate grade and high recovery rate simultaneously.
✅Ultra-Low Energy Consumption
- Permanent magnet design requires no electrical excitation, consuming only 10-20% of the power of electromagnetic separators. No cooling system needed, truly energy-efficient and environmentally friendly.
✅Durable Construction
- Drum shell made of 3-5mm thick non-magnetic stainless steel with wear-resistant rubber lining, service life up to 5-8 years. Magnetic system fully enclosed in stainless steel housing to prevent magnet detachment.
✅Flexible Process Adjustment
- Magnetic system deflection angle adjustable via threaded rod mechanism. Drum speed and slurry level can be easily adjusted to optimize separation performance for different ore characteristics.
✅Semi-Countercurrent Tank Design
- Optimized flow path ensures sufficient contact time between slurry and magnetic field, minimizing magnetic mineral loss in tailings. Suitable for roughing, cleaning and scavenging operations.
✅Simple Structure & Easy Maintenance
- Modular design with few moving parts. Daily maintenance only requires periodic inspection and lubrication, reducing downtime by up to 60% compared to complex separation equipment.
✅Multiple Configuration Options
- Available in downstream, countercurrent and semi-countercurrent tank types. Optional dry magnetic separators and high-gradient magnetic separators (HGMS) for special applications.
Working Principles
The YTO CTB magnetic separator operates based on the difference in magnetic susceptibility between minerals. Slurry enters the separation tank evenly from the feed box and flows through the semicircular separation chamber beneath the rotating drum. Under the powerful magnetic field generated by the internal permanent magnet system, magnetic particles are magnetized and firmly adsorbed onto the drum surface. As the drum rotates, these captured particles are transported to the concentrate discharge zone where the magnetic field strength decreases significantly, and are then washed into the concentrate launder by high-pressure water jets. Non-magnetic or weakly magnetic particles remain in the slurry and are discharged as tailings through the tailings outlet. This continuous process achieves efficient separation of magnetic and non-magnetic minerals.
