Break Seized Chain Pins Fast — No Torches. No Hammering.
Feed mill drag chain pins lock solid when dust packing forces them immobile during breakdowns.
Why Pins Seize in Feed Mills
Dust fines pack into link bores, trapping moisture and grinding surfaces. Heat, abrasion, and thermal cycling drive the pin tight until it won’t move. Downtime escalates fast when a seized pin blocks teardown and halts conveying.
Why This Failure Happens
Dust, fines, and feed mash pack into WH132, WH157, WDH102, and ER864 bores, creating compression lock. Abrasion and corrosion roughen the pin–bush interface until galling welds the contact surfaces. Load shocks hammer the frozen joint tighter, preventing teardown and extending outage duration.
