Annexus WA supplies, installs and maintains the DirtWhacker conveyor belt cleaning system.

Conveyor Belt Cleaning System

Dirt Whacker conveyor belt cleaner systems are recognized worldwide for their effectiveness, durability and belt-friendliness.

Our secondary cleaner, with its unique patented parallelogram design and air bladder system ensures a constant blade to belt angle of 90° and constant blade to belt pressure no matter the blade ware. The system is so effective that in the majority of installations, the pre-cleaning by a primary cleaner is not required.

The DirtWhacker cleaning system extends conveyor belt life, reduces blade ware and reduces ongoing maintenance.


  • Extended conveyor belt life
  • Constant blade to belt pressure
  • Blades operate independently
  • Constant blade angle of 90° due to patented parallelogram design
  • Lower maintenance
  • Longer blade life
  • Less carry back
  • Cleaner working environment
  • Less down time


In a coal application, the DirtWhacker Belt Cleaner was installed in a trial situation against a conventional spring-loaded belt cleaner. After 9 months, the belt with the conventional required replacement whereas the belt with the DirtWhacker belt cleaner lasted another 9 months. The reason for this dramatic difference is that the DirtWhacker removed a lot more of the coal from the belt, with less abrasive material passing over the blade and hence less abrasion on the belt. The big cost saving in this case was the replacement cost of the belt.
