Secondary Belt Cleaners: The Key to Reducing Carryback and Conveyor Maintenance
A thin layer of material left on a conveyor belt after discharge may not look significant, but across hundreds of operating hours it can create excessive cleanup, accelerate component wear, and increase maintenance costs throughout a facility.
Many operations install a primary belt cleaner and expect carryback issues to disappear. The reality is that even a properly functioning primary cleaner typically removes only 60% to 70% of initial carryback. The remaining material often consists of fines, moisture-laden product, and sticky residue that continue traveling down the return side of the conveyor. This remaining carryback is often responsible for some of the most expensive conveyor maintenance issues.
T
he Hidden Costs of Conveyor Carryback
Excessive carryback can contribute to:
- Material buildup on return idlers
- Pulley contamination
- Increased bearing wear
- Belt tracking problems
- Structural accumulation
- Additional dust generation
- Higher labor costs for routine cleanup
Why Secondary Belt Cleaners Matter
Signs Your Conveyor Could Benefit from a Secondary Cleaner
If you’re experiencing any of the following issues, your belt cleaning system may not be removing enough carryback:
- Return idlers constantly accumulating material
- Daily cleanup beneath conveyor structures
- Recurring belt tracking issues
- Excessive material buildup on pulleys
- Rising maintenance costs
- Increased dust generation around conveyors
These are often indicators that fines and residual material are bypassing the primary cleaner and continuing through the system.
A Cleaner Belt Creates a More Reliable Conveyor
The value of a secondary belt cleaner extends well beyond cleanliness.
Reducing carryback can help:
- Lower maintenance labor requirements
- Reduce component wear
- Improve conveyor reliability
- Minimize spillage and dust
- Improve workplace safety
- Extend equipment service life
For many facilities, the greatest return comes from preventing problems rather than cleaning up after them.
