Belt Damages

Dents, Small Deformation

      What is a dent 

        A dent is a local flatness deviation which either goes inside or outside and which does not snap outside or inside during the running of the belt or during external stress.

       How does a dent happen?

         The reasons for a dent are external forces which work from the outside or Inside onto the belt and which deform the belt material plastically.

   MEASURING METHODS

       Which measuring instruments are necessary a dent exactly ?

        -  meter or sliding caliper for determination of the size and the position

        -  precision ruler (75 mm or 200 mm long ) and feeler gauge (0.05 mm- 1 mm) for measuring the height (or depth)

  REASON OF BELT DAMAGE

A small screw falls between the belt and the drum or into the mat. Glue balls and mat forming defects.

    PREVENTVE STEP

Optimal mat forming (no glue balls, not mat doubling)

Check the scraper (to be in touch over the whole belt width and being Cleaned periodically).

Use a cleaning brush (also to be in touch over the whole belt width).

Install electro magnets in order to identify metal the mat.

Check brake layers

    POSSIBLE RISK IF DAMAGE WILL NOT BE REPAIRED

 Cracks will occur (maybe no single crack, so maybe a patch is needed)

   POSSIBLE REPAIR METHODS AND TOLERANCES

 Depending on the kind of deformation:

  -  flattening with the hammer
  -  shrinking method
  -  insert of patch by hand or Berndorf patching tool

   NECESSARY TOOLS

Flattening hammer or standard repair tools and patching tool

Cracks

       What is a crack.

        A crack is a local fracture. In most causes it is caused by overstress

- Single cracks

- A lot of cracks close to each other

MEASURING METHODS

Length of crack / visible on both sides ?  Are deformations visible near the crack ?

 REASON OF BELT DAMAGE

 Belt edge touches machine frame –if  edge cracks

 Foreign particle between belts or between belt and drum which and too big material defect

 Bad welding, Material fatigue .

 

        PREVENTIVE STEP

 Belt inspection from time to time (every 2 weeks ). Especially the edges

 

 POSSIBLE RISK IF DAMAGE WILL NOT BE REPAIRED

  The belt splinter / production stop

 

POSSIBLE  REPAIR METHODS  AND  TOLERANCES

- Single cracks can be welded

- A lot of cracks very close to each: insert pieces like round Patches or trapeze.

 

NECESSARY TOOLS

- Berndorf Standard repair tools

- Berndorf Patching tools
