Break Seized Chain Pins Fast — No Torches. No Hammering.
Pulp mill conveyor chain jammed and production is down—fix seized pins fast.
Why Pins Jam in Pulp Mills
Fiber slurry, steam, and corrosion pack the joint until the pin locks solid.
Pulp mills run hot, wet, abrasive environments that crush tolerances and load chain links unevenly. Fiber pack-out, corrosion, and thermal cycling weld pins into place. When the chain jams, production stops and crews don’t have hours to fight a frozen joint.
Why This Failure Happens
WH78, WH82, WDH110, WDH112, and ER864 joints trap steam, chemical residue, and fiber fines until the bushing galls the pin. Load spikes deform the barrel and lock the pin under compression. Heat, corrosion, and pack-out fuse the joint, causing total seizure and chain jam.
