Steel cord conveyor belts run down the main arteries in mines and are used not only for the transportation of bulk materials but also for man-riding. It is therefore essential they satisfy high safety and reliability standards in operation.

Precise information about any damage to the inner steel cords (steel wires) can be supplied by non-destructive magneto-inductive conveyor belt testing. This covers:

• Damage to the steel cords, e.g. strand and cord breakage and corrosion
• Irregularities in cord pitch and splice
• Other irregularities

Our testing programme includes:

• Testing of all types of steel cord conveyor belts
• Testing at conveyance speed
• Testing while in operation; test equipment on bottom belt during conveyance
• Testing in hazardous areas where there is a risk of firedamp and explosion (approved equipment)
• Testing of special conveyor types, e.g. toothed belt
• Cover thickness measurement (on request)

Interpretation and assessment of the measured test data provides you with a complete status or test report. By carrying out damage analysis at an early stage it is possible to plan any necessary repair and maintenance work to be carried out at a time when your operations can best afford it.

Testing is carried out by our accredited DMT Laboratory for Non-destructive and Destructive Testing - Rope Testing Centre.
