Beltcheck for condition monitoring of conveyor belts
November 2011Maintenance, Test & Measurement, Calibration
Condition monitoring of conveyor belts is important as timely information can be gathered and used to take preventative action – it is more cost effective to repair a conveyor belt before a breakage occurs. Traditionally, Vernier gauges are used to measure the side thickness of such belts when stationary, but the largest amount of wear is usually found in the middle portion of the belt where loading takes place.
For this purpose, Beltcheck TH 40 is equipped with a probe attached to a 1 m long cable making it possible to reach the mid-sections of conveyor belts to determine the wear in the areas where it is needed the most. This information aids plant managers in recording and tracking the deterioration of belts over their lifespan. Being portable, this instrument can be used to spot test several conveyor belts in different locations and is not tied to a single belt such as an online system.
The Beltcheck is also not tied to a particular software method, for example, some users might require only three spot measurements across the width of the belt per running metre of belt material, while others might demand more. Other users might decide to scrutinise a particular wear pattern with numerous measurements of a particular belt under inspection. Wear patterns show considerable differences and are influenced by factors such as climate, size of material and anomalies of the particular belt.
An actual case study illustrates this: with a particular conveyor belt it was found that the mechanical chute was directed slightly off-centre which resulted in one side of the belt being considerably worn while the other was almost new. The maintenance team decided to turn the belt around so that the newer side was now being loaded, once this side has been worn to the same degree the belt will be replaced and the chute properly aligned.
