Broken rollers or large jagged rocks, coal, salt and other materials can cause serious damage to the conveyor belt system. If materials with jagged edges stick to the support structure of the conveyor, tears, rips, or tears will appear on the belt, and the system must be shut down and the belt repaired.

When belt damage occurs, it is vital to avoid long downtime and expensive repairs, which are usually related to the conveyor returning to service after an accidental belt tear. Whether the fault is small or large—longitudinal tears, small punctures, soft spots, or even holes—there are tear repair methods that can temporarily protect the integrity of the damaged belt and restore it in the shortest possible downtime. run.

Always remember that when a lateral tear extends from the edge of the belt to a belt width of 25% or more, the damaged area should be cut off and a new joint installed.

Pro tip: If repeated cracks and tears are a problem, having a crack repair kit with installation tools and fasteners of different sizes will enable you to respond quickly and reduce downtime losses.

For the longitudinal tear and wear points of heavy belts with a thickness of 1-3/16” (30mm), the use of mechanical tearing to repair fasteners is usually a cost-effective solution. Mechanical tear repair fasteners provide Advantage:

  • Quick installation
  • Lower cost
  • Almost no belt waste
  • On-site workers can install with simple tools
  • Basic tear repair

Here are some best practices for tear repair in various applications:

  • For small punctures, place a standard bolted solid plate fastener across the belt in the damaged area.
  • For larger holes, bolts and solid plate fasteners can be used to patch on the original belt. Remember to paint the corners first, and then paint the rest of the fasteners.
  • In order to clean the longitudinal cracks, the crack length of standard bolted solid plate fasteners can be used. The spacing should not allow any material to penetrate. Here is a good example of a longitudinal tear that needs to be repaired.
  • Usetear plates with three-bolt fasteners to prevent jagged or longitudinal tearing or bridging soft spots. Note the position of the three bolt fasteners on the cable. Two of the three bolts should be placed on the weak or “flap” side of the jagged tear to increase stability. It is recommended to use two or three bolt fasteners alternately to help adjust the fastener line as close as possible.
  • For quick temporary repairs, it is recommended to use turtle fasteners every 4 to 6 inches (101 to 152 mm). Remember, turtle-shaped and three-bolt tear repair fasteners should not be used to connect the two ends of the belt together. Here is an information document that explains how to install these fasteners.

The tear repair fastener keeps your production moving until a permanent repair can be made during planned downtime. Implement bolted solid plate fasteners as part of your operations, and observe how fast you can recover from a belt breakdown.
