Protect your crushers, shredders, and grinders from catastrophic damage.
Consider our Custom Ferrite Magnetic Head Pulleys.
They are suitable for the Mining, Aggregate, and Bulk Recycling industries.
These pulleys replace your standard conveyor drive roller.
Transform the discharge point into a powerful self-cleaning separator.
Neodymium magnets are for fine powders.
Our Deep Reach Strontium Ferrite (Ceramic 8) systems are built for heavy burdens.
They generate a voluminous magnetic field that penetrates through thick rubber belts (up to 25mm+).
And heavy material burdens.
Capture large Tramp Iron before it destroys your downstream processing equipment.
Such as bucket teeth, railroad spikes, and angle iron.
Engineering & Manufacturing Capabilities
Deep-Throw Flux Circuit:
We use an Axial Pole configuration with massive ferrite blocks.
This design sacrifices surface gauss (typically ~2,000 Gauss).
But maximize the Magnetic Gradient.
Extend the pulling force 200mm to 400mm away from the pulley face.
This ensures capture even when material is tumbling mid-air.
Robust Shell Construction:
The magnetic core is sealed inside a non-magnetic Stainless Steel 304 or 316 shell.
We use heavy-wall tubing (Sch 40 or Sch 80).
They can resist the impact of heavy rocks and abrasive ores.
Shaft Integration:
We don’t just weld a bar to the end.
We use XT or QD (Quick Detach) Bushing Hubs or precision-machined oversized shafts.
This allows for easy maintenance.
And ensures the pulley can handle high torque from the drive motor without shearing.
Customization Options
A. Lagging & Traction
A bare metal pulley will slip under a heavy belt.
We offer hot-vulcanized lagging options:
1). Diamond Pattern Rubber:
10mm – 12mm thick, 60 Duro rubber for water shedding and maximum belt grip.
2). Ceramic Lagging:
Embedded ceramic tiles for extreme wear resistance in mining applications (high abrasion).
3). Smooth Rubber:
For dry, light-duty recycling applications.
B. Dimensions & Crown
Crowned Face:
We machine a standard taper (crown) onto the pulley face.
Ensure proper belt tracking (self-centering).
Flat Face:
Available for specialized wide-belt applications.
Custom Sizes:
Begin from standard 8-inch (200mm) diameters for portable crushers.
As large as massive 48-inch (1200mm) pulleys for main mining conveyors.
C. Shaft Machining
Keyways:
Machined to ANSI or Metric (DIN) standards to fit your gearbox/motor coupling.
Stepped Shafts:
Custom turn-downs for bearing blocks (Pillow blocks).
Don’t let a stray bolt stop your plant.
Sizing a magnetic pulley depends on your Belt Speed and Burden Depth.
If the belt moves too fast, the iron might fly past the magnet.
