There are many issues to consider when specifying the most appropriate conveyor belt cleaner.An important consideration is how to maintain proper tension for optimum cleaning performance without introducing related problems.Inadequate tensioning causes carryback to cling to the belt and spill along its path,piling up under the conveyor and emitting excessive dust.This requires extra labour for clean-up and can affect air quality Over-tensioning leads to friction damage to the carrying side of the belt,premature blade wear and potential splice damage.Both scenarios contribute to unsafe work conditions and raise the cost of operation.There are two basic approaches to applying tension to the belt cleaner: linear and rotary The blades cleaning position and angle of approach to the belt often dictate whether a linear or rotary ten-sioner is used.
