Want to achieve superior recovery of magnetite and ferrosilicon?
Consider our Custom Wet Drum Magnetic Separators.
Built for Heavy Media Separation (HMS) plants and Iron Ore Concentration circuits.
Our Low Intensity (LIMS) and Medium Intensity (MIMS) separators can capture highly magnetic particles.
Extract them from liquid slurry streams with up to 99.8% recovery efficiency.
Unlike dry drums, a wet drum requires precise hydrodynamic balancing.
We customize the Tank Design to match your specific particle size and flow velocity.
Ensure that valuable magnetic media is recovered.
Meanwhile, non-magnetic gangue (silica/rock) is washed away.
No matter you are running a Cobber, Rougher, or Finisher stage.
Our drums deliver the high magnetic gradient.
And Minimize media consumption and operating costs.
Tank Flow Styles (The Core Engineering)
The effectiveness of a wet drum depends entirely on the tank interaction.
We offer all three industry-standard configurations:
A. Concurrent Tank (Flow with Rotation)
Best For:
Coarse feeds and high feed densities (Cobbing).
Function:
The slurry flows in the same direction as the drum rotation.
Result:
Produces an extremely clean concentrate.
The magnetic material is pulled out immediately.
And coarse rock passes through the bottom tailings gap without jamming.
B. Counter-Current Tank (Flow against Rotation)
Best For:
Finishing stages and medium-to-fine particles.
Function:
The slurry flows opposite to the drum rotation.
Result:
Provides the highest recovery rate for finer particles.
The magnetic material must swim against the current.
Ensure that even the smallest magnetic fines are captured before they can escape to tailings.
C. Counter-Rotation Tank (Steep Gradient)
Best For:
Heavy surges and extremely fine finishing.
Function:
The drum rotates against the slurry flow.
But the feed enters directly into the high-magnetic zone.
Magnetic Element Construction
Inter-Pole Design:
We use a specialized multi-pole magnet assembly (Main Poles + Inter-Poles).
As the drum rotates, the magnetic field reverses polarity multiple times.
This causes the magnetic cluster to “tumble” or “flip” on the drum surface.
Shake loose entrapped non-magnetic water and dirt (gangue) to produce a drier, higher-grade product.
Field Intensity:
Standard LIMS:
900 – 1,200 Gauss (Ferrite) for Magnetite/Ferrosilicon recovery.
MIMS:
3,000 – 6,000 Gauss (Rare Earth Hybrid) for recovering weak oxides (Hematite/Martite) or scavenging tailings.
Wide-Angle Arc:
Our magnet element covers a 135° to 150° pickup zone.
Maximize the time for dewatering and washing before discharge.
Wear Protection & Durability
Mining slurries are incredibly abrasive.
We build for longevity.
Drum Shell:
Manufactured from non-magnetic Stainless Steel 304 with precision-machined end flanges.
Sacrificial Wear Layers:
Linatex / Rubber Lining:
3mm to 6mm hot-vulcanized rubber applied to the drum shell and tank surface.
They can resist abrasion from coarse sands.
Ceramic Tile Lining:
Optional for high-velocity feed boxes to prevent steel erosion.
Bearings:
Double-row spherical roller bearings housed in triple-sealed pillow blocks.
Mounted outside the tank to prevent slurry ingress.

Media consumption is a major operating cost.
