Break Seized Chain Pins Fast — No Torches. No Hammering.
Fertilizer drag conveyors shut down fast when corrosion locks chain pins solid.
Why Pins Seize in Fertilizer Plants
Corrosive dust, chemical vapors, and constant abrasion attack chain joints. Rust builds, pins gall, and alignment loads freeze them in place. Downtime escalates fast when a seized pin stops the drag line.
Why This Failure Happens
Corrosive fertilizer fines infiltrate WH132, WDH159, and ER864 joints, packing the bushing until rust bonds the pin solid. Thermal cycling and shock loads drive the pin deeper, increasing friction and shear lock. Once seized, the chain stops tracking, stalls under load, and forces an immediate shutdown.
