The Stockpile · Pile 02 — The Parts
Rubber and urethane sealing that seals without plowing.
All cut to size for your chute width. Clamps and hardware stocked alongside — skirting only works with clamps that hold adjustment.
Skirting should ride the belt lightly and seal the gap — not dig in. Rubber softer than the belt cover, adjusted to kiss rather than press, sealing against a supported belt. Skirting that plows grooves the belt lengthwise, and that damage is permanent. If your skirting wears out fast or your belt shows parallel grooves, the setup — not the rubber — is the problem.
Skirting seals only if the belt underneath cannot sag away from it: skirting + clamps + belt support (impact beds or close-spaced idlers) work as one system. We stock and install all three.
| Situation | Spec | Why |
|---|---|---|
| General load zone sealing | Purpose-made skirting rubber, clamp-mounted | Conforms at low pressure — seals without plowing |
| Dusty fine material | Dual-seal / multi-lip systems | Primary seal takes material, secondary takes dust |
| Heavy abrasion at the wall | Wear liner inside + rubber outside | Liner takes the load; rubber only seals |
| Constant readjustment complaints | Quick-adjust clamp systems | Five-minute maintenance gets done; bolt-fights don’t |
| Old belt used as skirting | Replace it | Belt rubber resists wear instead of sealing — grooves the belt and leaks anyway |
| Symptom | Likely cause | Fix |
|---|---|---|
| Leaks right after every adjustment | Belt sag between idlers opening the gap | Support first — bed or closer idlers — then seal |
| Rubber wearing in weeks | Material bearing on the seal — liner gone | Restore the wear liner |
| Grooves worn into the belt | Skirting over-clamped, or belt-as-skirting | Proper rubber, kissed to the belt, not pressed |
| Dust puffing over the top | Air displacement with no exit path | Settling zone / curtains — it’s an air problem |
In demanding wear zones, orange natural rubber runs 3–5× black rubber; urethane adds low friction and high tensile strength for dust-critical points. Longest-lasting is whichever is set up to seal instead of plow.
Common duty runs 1/4″ to 1/2″; heavier impact zones go thicker. Send belt width, material and lump size — we’ll spec it with the right clamps.
Yes — transfer-point sealing is core crew work, usually paired with belt support so the seal actually holds.
