Belt CleanersResidual carryback of fines and dust adhering to conveyor beltspresents a sticky challenge. Expensive maintenance and safetyproblems created by carryback are so prevalent that CEMA recommendsthe installation of at least one belt cleaner at each conveyordischarge point.Link-Belt ® Scavenger Belt Cleaners effectively eliminate carrybackbefore it causes expensive maintenance and safety hazards and reducecosts associated with maintenance as well as blade and conveyor beltreplacement.The potential for cost savings to operators is integral to the Scavenger design. The heartof the technology is a patented parallelogram design that ensures consistent blade-to-beltcontact, pressure and angle across the full width of the conveyor belt. The entire belt iscleaned equally, with the Scavenger automatically adjusting for load to achieve consistencyas the blades endure wear.Enhanced belt life is also addressed through the Scavenger's modular parallelogram units which form multipleblunt blade arrangements that exploit the flexible properties of the rubber belt, squeezing rather than scrapingembedded material from the belt. The squeezing action eliminates abrasive material before it passes over theblade, thus preserving and extending both belt and blade life. In addition, the blunt, wear-resistant tungstentippedblades produce a low-friction, favorable wear relationship between the belt and blades which contributesto longer service life for the blades.Link-Belt Scavenger Belt Cleaners require no mechanical adjustment between blade changes. Consistent pressureis maintained through a pressurized air bladder which supports all parallelogram modules in the cleaning unit.The pressure gauge provides a visual indication of blade-to-belt pressure which can be adjusted remotely asrequired.Both primary and secondary models are offered. Features include:●●●●●●Precise pressure control to maximize belt and blade lifePre-determined blade to belt angle remains constantRemote pressure monitoringNo mechanical adjustment of blades between blade changesModular components for cost-effective maintenance and easy exchangeFully compatible with reversible belt systemsOptional accessories include a no-load device to de-activate the cleaner when there is no material on the belt,and a clip avoidance system which detects mechanical joints and momentarily reduces pressure in the airbladder to allow the joint to pass over the blades with a minimum of resistance and interference.Call the factory for assistance in belt cleaner selection.27
