Scrap Belt Tracking and Alignment

Before You Begin

Safety: Stop the machine, follow the site lockout/tagout procedure, verify that hazardous energy is controlled, and release or secure stored mechanical and pneumatic energy before opening a panel, removing a guard, or adjusting components. Electrical work must be performed by a qualified technician.

Realigning the scrap belt can be a tedious process.

The first rule of belt tracking:

The belt tracks toward the side with the least tension.

This rule applies to both ends of the belt conveyor.

The second rule of belt tracking:

If the belt is not tight enough, it will not track correctly.

Tension the belt evenly. The belt should sit snugly on top of the rollers at both ends, without a gap.

While the belt is running, apply pressure where the belt contacts the roller. The top of the belt should not lift away from the roller. If it does, the belt is not tight enough.

• The tension bolts need to be fairly close to the same length.
• Set the drive side at a measured length so the threaded rods are the same
• Then do most of the adjustment on the idler side.
• If the belt is moving to the right you have two choices extend the right threaded rod or loosen the left one. Note: It is best to over correct for a couple turns and then relieve it after the belt gets in the correct position.
• The goal is to get it to track on the idler end while keeping it centered on the drive end.
• After the belt is tracking correctly on the idler end there may be adjustments required to the drive end to center the belt.

What Correct Looks Like

• The belt tracks at the idler end while remaining centered at the drive end.
• The belt stays snug on the rollers and does not lift when light pressure is applied.
• Stop and correct the adjustment if the belt walks toward an edge, lifts, or rubs the frame.

Reinstall all guards and restore energy through the approved startup procedure. Run a controlled no-load test, watching for binding, tracking changes, unusual noise, vibration, leaks, or unexpected movement before returning the machine to production.

If the issue remains, record the exact on-screen message, affected component, indicator-light state, and the last change made. Provide those details to Enventek Technical Support; do not repeatedly recalibrate or replace parts without identifying the cause.
