For underground projects, such as tunnel construction, conveyor systems have a significant advantage over trucking & hauling. In addition to running quietly, conveyors emit little exhaust. Fewer toxic fumes mean fewer requirements for air scrubbers and exhaust removal. Conveyors are also cleaner and more efficient.
The equipment efficiency of belt conveyor is improved either by introducing highly efficient equipment or improving the efficiency of the existing equipment. The idler, belt and drive system are the main targets for equipment efficiency. All the longitudinal main resistances are transferred via the idlers, hence the idlers have a great impact ...
