Adjustment of the Cleaner Tension

Lastly, the tensioning of the belt cleaner is a key performance factor, and often confused part of cleaning the conveyor efficiently. A common misconception is that if more pressure is applied to the blade, better results will be achieved. This statement is only partially true. Previous studies have shown that over-tensioning of the cleaner increases frictional drag on the belt, decreasing the wear life of the cleaner whilst also increasing the overall power consumption of the conveyor.

If fasteners have been added to the belt to fix tears, over-tensioning the belt cleaner may result in the cleaner being damaged or the fasteners being forcefully removed, further damaging the valuable conveyor belt.

Some belt cleaning systems have centralized torque transmitters, engineered to self-adjust and maintain an evenly distributed yet concentrated pressure on the centre of the belt, where the majority of the cleaning is required.

Conclusion

Correct belt cleaning should never be an overlooked element in conveyor maintenance. If a well engineered cleaner is installed correctly, considering these five factors, not only will the cleaner get optimum life but so will the other associated conveyor componentry, the valuable belt and structure of the conveyor itself. The role of maintenance is transformed from fixing breakdowns to optimizing overall productivity, placing the maintenance function at the heart of the quality improvement process.
