Break Seized Chain Pins Fast — No Torches. No Hammering.
Drag conveyor chain pins seized from cement dust are stopping production and burning hours of outage time.
Why Pins Seize in Cement Plants
Cement dust packs into the pin joints until movement stops under load. Heat, abrasion, and corrosion lock the pin solid. Downtime escalates fast when a seized pin blocks the drag conveyor and crews can’t drive it out safely.
Why This Failure Happens
Cement dust infiltrates WH132, WDH159, ER864 and similar chains, forming packed, abrasive sludge. Load shocks and thermal cycling force this contamination deeper, galling the pin and bushing until the joint seizes. Once seized, the chain won’t articulate, stalls the drag, and the pin will not press out by conventional means.
