Double Drum Magnetic Separator Machine Diagram • Engineering Schematic
The CAD technical schematic below details the internal geometry, stationary magnetic arc assembly, and material flow paths of the NSW-DMDS-9001200 model. The engineering roller type magnetic separator diagram depicts the feed hopper with feeder springs, primary drum shell, intermediate transfer chute, secondary scavenger drum, and independent discharge chutes.
Two-Stage Cascade Working Principle • How Double Drum Extraction Works
The double drum architecture uses a two-step sequential magnetic cascade that dramatically outperforms standard single-drum setups:
- Stage 1 (Primary Extraction): Raw bulk material discharges uniformly from the top vibratory feed hopper onto the first revolving stainless steel drum. Ferrous contaminants and magnetic iron ore particles are instantly captured by the 180-degree stationary internal magnet arc and carried beneath the drum before releasing into the primary magnetic discharge chute.
- Transfer & Agitation: The non-magnetic tailings fall by gravity through the internal angled transfer chute, mechanically agitating and turning over the material to unmask any trapped fine ferrous particles.
- Stage 2 (Secondary Scavenging): The stream lands on the second magnetic drum, which performs a high-intensity finishing sweep. This ensures that even weakly magnetic particles, magnetic dust, or high-speed bypass iron missed in Stage 1 are completely captured, yielding ultra-pure non-magnetic product in the clean tailings chute.

Comparison • Double Drum vs. Single Drum vs. Belt & Roller Type Separators
Depending on your material burden depth, particle sizing, and purity requirements, N.S. Engineering Works manufactures diverse magnetic separation systems. Here is an engineering comparison between our drum units, belt type magnetic separator units, and 3 roller magnetic separator systems:
| Separator Type | Configuration | Best Suited Applications | Purity Level |
|---|---|---|---|
| Double Drum Separator (NSW-DMDS) | Two Revolving SS Drums in Series | High-volume mineral ores, sponge iron, foundry slag, quartz, recycling | 99.5%+ High Purity |
| Single Drum Separator (NSW-MDS) | Single Revolving SS Drum | Tramp iron removal, general foundry scrap, bulk slag primary scalping | 90% – 95% Standard Purity |
| Belt Type Magnetic Separator | Cross-Belt / In-Line Overband Magnet | Installed above magnetic separator conveyor belt for large tramp metal | Equipment Protection |
| 3 Roller Magnetic Separator | Three High-Intensity Rare Earth Rollers | Fine dry powder, silica sand, glass sand, feldspar, paramagnetic mineral separation | 99.8%+ Ultra High Purity |
Frequently Asked Questions • Double Magnetic Drum Separator
1. What is the magnetic separator machine price for double drum models in India?
The magnetic separator machine price for a heavy-duty double drum unit (such as 900 × 1200 mm, 15 TPH) typically ranges around ₹7,50,000 depending on drum shell diameter, face width, motor drive specifications, and magnetic flux intensity (2,500 Gauss to 4,500+ Gauss NdFeB). N.S. Engineering Works provides direct workshop pricing from Mandi Gobindgarh with zero dealer commissions. Contact us at +91 8272861892 for an itemized factory quotation.
2. How does a double drum separator differ from a belt type magnetic separator on a conveyor belt?
A belt type magnetic separator (also known as an overband cross-belt magnet) is installed suspended above a magnetic separator conveyor belt to extract large tramp iron and protect downstream crushers. In contrast, a double drum magnetic separator handles bulk granulated material directly through a top hopper, providing continuous two-stage separation with 360-degree rotation and higher extraction purity for mineral fines.
3. When should I choose a double drum unit versus a 3 roller magnetic separator?
A 3 roller magnetic separator or rare-earth roller type magnetic separator is best suited for fine, free-flowing dry powders (such as high-purity silica sand, glass sand, and feldspar) where magnetic flux exceeds 10,000 Gauss to capture weakly paramagnetic mineral specs. A double drum magnetic separator is designed for heavier, coarse-to-medium particle burdens (slag, sponge iron, minerals, foundry scrap) requiring rugged stainless steel wear shells and high hourly capacity (up to 15 TPH).
4. Why is N.S. Engineering Works ranked among leading magnetic roller manufacturers in India?
As established magnetic roller manufacturers in india, N.S. Engineering Works utilizes certified strontium ferrite and NdFeB magnet blocks, dynamic balancing, non-magnetic SS-304 drum shells, and heavy-duty structural channel fabrication. Each machine undergoes 100% magnetic flux mapping and mechanical trial running prior to dispatch from Mandi Gobindgarh.
5. Does N.S. Engineering Works integrate with eddy current separators for non-ferrous metals?
Yes. In complete metal recovery and electronic waste recycling plants, our double drum magnetic separator is installed as the primary ferrous removal stage, extracting 100% of iron scrap. The remaining non-ferrous stream (aluminum, copper, brass) then feeds smoothly into high-speed eddy current separators supplied in collaboration with certified eddy current separator manufacturers in india.
6. How does a magnetic destoner rod compare with a permanent magnetic drum separator?
A magnetic destoner rod (or magnetic tube grid) is a static high-gauss bar placed inside grain chutes or hopper throats to manually catch fine metal pieces and magnetic stones during batch processing. In contrast, a double magnetic drum separator is a continuous, self-cleaning industrial machine designed for massive throughput (up to 15 TPH) without manual cleaning downtime.
7. When should I choose a single drum versus a double drum magnetic separator?
A single drum separator is ideal when the objective is basic tramp iron removal or primary slag scalping where 90-92% recovery is sufficient. When material requires high-purity iron concentrate (e.g. sponge iron beneficiation, quartz sand cleaning, or high-value metal recovery), our double drum separator guarantees that any bypass iron from the first drum is captured by the second drum for up to 99.5%+ recovery.
