Chain Conveyor Chain Failure Problems for Paper Mill

Malfunctioning chain is the most common source of disruption in a Chain Conveyor. Operators frequently encounter problems like severe chain elongation and wear, complete seizure or jumping off the sprockets, and deformed or cracked carrier plates. These issues typically originate from a few key operational oversights. Inadequate or incorrect lubrication leads to dry friction within the chain pins and bushings, accelerating wear.

Running the Chain Conveyor beyond its designed load capacity strains components, speeding up wear and deformation. The inevitable aging and metal fatigue from normal use also contribute, but this is drastically worsened by environmental factors like the ingress of abrasive contaminants (dust, fiber, grit) into the chain joints. Finally, improper chain tension—either too tight (increasing load) or too loose (causing bounce and derailment)—is a major culprit behind erratic performance and premature failure.

The solution set includes:

1. Strict Lubrication Protocol: Use a suitable, adhesive grease and follow a regular schedule to ensure lubricant penetrates the internal pin and bushing interfaces.

2. Correct Tension Adjustment: Maintain proper sag, typically 2%-4% of the center distance, using the tensioning device to prevent undue stress or slack.

3. Precision Alignment: Ensure the head and tail sprocket shafts are parallel and aligned to prevent side-running and uneven wear.

4. Timely Component Replacement: Replace chains showing over 2% elongation and damaged carrier plates promptly, preferably in matched pairs.

5. Regular Cleaning: Frequently remove accumulated material and debris from the chain and its tracks to prevent abrasive contamination.
