Mineral powder is heavy, abrasive and unforgiving: it grinds the base on every lift and finds any gap in the seam. This bag is built with thickened high-density PP, a reinforced base and a tight weave with fine stitching — sized 900×900×1200 mm for the 1000–1500 kg loads typical in mining and metallurgy.
Values below are the build we ship most often for ore powder and industrial mineral powders. Bulk density and particle shape are the two inputs that change the numbers fastest — send those with your enquiry.
| Parameter | Typical value | Note |
|---|---|---|
| Product Name | Mineral Powder FIBC Bulk Bag | Wear-resistant, leakage-proof FIBC |
| Bag Construction | Circular (tubular) / U-panel | U-panel for a squarer stack |
| Material | Thickened high-density virgin PP | No recycled content in load-bearing panels |
| Dimensions | 900 × 900 × 1200 mm | Other heights for your silo outlet |
| SWL | 1000–1500 kg | Confirm with bulk density |
| Safety Factor | 5:1 | 6:1 for rail, repeated lifting or third-party audit |
| Top Options | Open top / filling spout | Spout with tie for dust control |
| Bottom Options | Flat / discharge spout | Reinforced spout throat for abrasive flow |
| Base | Reinforced / cross bottom | Cross or lattice base spreads load |
| Lifting Loops | 4 corner loops, heavy webbing | Extra stitch passes for 1500 kg |
| Fabric Weight | 120–170 g/m² | Heavier base panel than body |
| Coating / Lamination | Optional | Dust and moisture barrier |
| Inner Liner | Optional PE 0.05–0.08 mm | Liner takes the abrasion instead of the weave |
| Printing | 1–3 colours | Brand, grade, net weight |
| Colour | White (standard) / grey | Dark colours hide handling marks |
| Electrostatic Type | Type A | Type B or C if the dust is combustible |
| UV Stabilisation | Strongly recommended | Outdoor stockyards degrade untreated PP fast |
| Stitching | Double chain stitch, reinforced | Extra passes at loop and spout |
| Packaging | Bale 5 / 10 pcs or pallet | Baled for container fill |
Two mineral powders with the same name can need different bags. These are the fields we adjust.
Chosen from bulk density and edge sharpness, not from habit.
Distributes point load away from the centre of the base.
Higher tenacity webbing and extra stitch passes above 1200 kg.
Wear concentrates at the discharge throat — doubled there.
Sacrificial barrier against abrasion and moisture.
Switched when the powder is combustible, not before.
For stockyards and open storage; specify months of exposure.
6:1 built differently — heavier loops and base, not a label change.
Mineral powder does not break a bag in one lift. It wears the base thin over dozens of trips, then splits at the worst moment — usually in a container or on a quay.
Where this build is used, and what changes between them.
Iron, copper and zinc concentrates; 1200–1500 kg loads.
Sharp particles — liner plus heavier base is the usual answer.
Cold-resistant fabric for winter loading in northern ports.
The base and the discharge spout take almost all the wear. This is where we spend the material.
Selected steps from our woven-PP line. Full capability on the factory page.
Heavy tape woven to 120–170 g/m².
Cross or lattice bottom, doubled panel.
Cut to 900×900×1200; grade marking.
Extra stitch passes at loops and spout.
Load check, seam check, baled for export.
Weaving the heavy end of the range ourselves is what makes a 1500 kg 6:1 bag practical: we can change tape width and fabric weight on the loom instead of accepting whatever a fabric supplier has in stock.
