Stopping Flight Diameter Loss on a Limestone Screw Conveyor
Custom contoured SCProbond™ N flight plates kept a limestone screw conveyor's flights from wearing thin — manufacturing marks are still visible on the surface after months of continuous service.

20+ Months, Diameter Preserved
Executive Summary
The Bottom Line
A returning SCP customer's limestone screw conveyor was steadily losing flight diameter to continuous abrasive wear, cutting into conveying efficiency. Custom contoured SCProbond™ N flight plates, manufactured to the exact dimensions of the screw and housing, have kept diameter intact for over 20 months and counting — with a related shaft liner running two full years with no noticeable wear.

The challenge
Flight Diameter Loss Under Continuous Wear
A returning SCP customer's screw conveyor flights were steadily losing diameter under continuous abrasive limestone conveyance. As the flights wore thin, conveying efficiency dropped, and the equipment would eventually need full replacement — a costly and disruptive outcome the customer wanted to avoid.
01
Capture Exact Dimensions
The customer provided the exact dimensions of both the screw and housing so every plate would fit precisely.
02
Manufacture Contoured Plates
SCP manufactured custom contoured 90-degree SCProbond™ N flight plates lining the full length of the conveyor.
03
Extend to Related Components
Building on the result, the same customer added an SCProbond™ shaft liner and reconfigured feed chutes with SCP product.
The results
Measured Impact in the Field
20+ Months
In Service, Diameter Preserved
The contoured flight plates have extended conveyor lifetime by over 20 months and counting.
~80,000 Tons
Abrasive Material Processed
Manufacturing marks are still visible on the flight plate surface after this volume.
2 Years
Wear-Free Shaft Liner
The original shaft liner had worn through in under two years before switching to SCP.
SCP made a shaft liner for our air separator, the original lasted less than 2 years before it was worn in two pieces. Since we installed the SCP liner we have run for two years with no noticeable wear … Last year we reconfigured a couple feed chutes with all SCP product. The writing from the manufacturing process is still visible after running nearly 80,000 tons of 1/4" minus over it.
