Wet Drum Magnetic Separator

Wet Drum Magnetic Separator Manufacturer, Supplier

With rich experience of making high quality magnetic equipments, we offer highly efficient wet drum magnetic separator widely used in the metal processing industry. It play significant role to remove very fine ferrous and other magnetisable impurities from the material.

Magnetic Drum Separator is used for low viscosity liquids. It is provided with semi- circular separating chamber fixed just beneath drum made of high quality stainless steel. Drums are provided with cylinders containing permanent magnetic discs. Cylinders are used to make high-gradient magnetic field. They efficiently remove magnetisable particles along with ferro-sillicon particles from the material. They also used for the dense media like iron ore. Some application needs very pure form of the end products. For such specific products, rare earth magnets are used. Strong and high field gradients are used to remove very fine contaminants from the medium. Our resourceful rare earth magnets are very effective for the weak contaminants and also for dense mediums of material.

We provide wet drum magnetic separator in different size, shape and configuration. It is also available with single drum and double drum design. For double drum arrangement, two separators are fixed back to back. We also offer multiple drum application.

  • Permanent magnets facilitate with proficient functioning and eradicate coil burn-outs
  • High recovery and discharge of contaminants
  • High grade material of construction
  • Bolted design ensures safe and fast operations
  • Used to obtain pre-concentrate extracts

High-Performance Wet Drum Magnetic Separation Solutions

Wet drum magnetic separators are engineered for the continuous extraction and recovery of ferromagnetic materials from wet process slurries. These systems are highly critical in heavy media recovery circuits (such as magnetite or ferrosilicon recovery) and iron ore concentration plants. Featuring a stationary, high-intensity internal magnetic element enclosed by a rotating stainless steel drum shell, our separators generate high magnetic gradients that capture even the finest magnetic particulates, ensuring clean tailings discharge and maximum recovery rates.

Designed to withstand abrasive and demanding processing environments, our wet drum magnetic separators offer multiple tank styles (including concurrent, counter-rotation, and counter-current) to suit specific feed concentrations and particle sizes. The robust construction and optimized magnetic circuits minimize operating costs, prevent clogging, and provide stable operation under fluctuating slurry flow rates, making them the standard choice for mineral processing and mining operations worldwide.

FAQs About Wet Drum Magnetic Separators

1. How does a wet drum magnetic separator work? + Slurry flows into the separator's tank where a rotating drum with a stationary internal magnet captures ferromagnetic particles. The magnetic particles stick to the drum's surface and are carried out of the slurry zone to be discharged, while non-magnetic minerals pass through as tailings.
2. What are the main applications of wet drum separators? + They are primarily used in coal washing and mineral processing plants to recover heavy media like magnetite or ferrosilicon, and in iron ore concentration plants to upgrade iron ore slurry.
3. What is the difference between concurrent and counter-current tanks? + In concurrent tanks, slurry flows in the same direction as drum rotation, suitable for coarse separations. In counter-current (and counter-rotation) tanks, slurry flows against the drum rotation, which provides high recovery rates for very fine particles.
4. Are rare earth magnets used in wet drum separators? + Yes, rare earth (neodymium) permanent magnets can be used when high magnetic field strengths are required to capture weakly magnetic or extremely fine particles that ferrite magnets cannot retrieve.
5. What maintenance is required for these separators? + Maintenance is relatively low. It involves checking wear on the drum shell and tank liners, lubricating the drum bearings regularly, and verifying that the drum drive alignment remains correct.
6. Can these separators handle varying slurry density and flow rates? + Yes, our optimized tank designs and stationary magnet configurations are engineered to maintain high separation efficiency even under moderate fluctuations in feed rate and solid concentration.
