How To Adjust Trough Alignment During Installation
Trough end flanges must be flush with each other to achieve proper trough alignment, which is critical to long term operation. If trough end flanges have been damaged in transit or during the installation process, adjustments may be required prior to operation. The stringline method can be used to verify trough alignment.
To adjust trough alignment, begin by loosening all bolts at the misaligned trough joint.
Using a rubber mallet, gently tap trough end flanges in appropriate direction. Use increased force as required to bend trough end flanges to proper location.
When viewing troughs from the top, if the trough flange connection naturally pushes to the right, the left side of the trough end flanges must be adjusted to the proper location. The opposite is true for trough flange connections that naturally push to the left.
Tighten all bolts after making minor adjustments to the trough end flange connection and verify alignment using the stringline method. Repeat this process as required until all troughs are properly aligned.
After troughs are properly aligned, tighten all trough flange connections to the proper torque specification. Verify that troughs have maintained proper alignment after torquing bolts.
Always read the complete KWS Operation, Installation, and Maintenance Manual before installing, operating, or maintaining a screw conveyor.
