  • the present invention relates to a method for determining a section-related running friction resistance of the belt conveyor system that is in operation.
  • Belt conveyor systems which are used above or below ground have been known for decades, particularly in mining and in industry. They are primarily used to transport bulk goods such as overburden, ores, fuel and building materials, even over longer distances. Belt conveyor systems can therefore be several kilometers long and transport several thousand tons of bulk material per hour.
  • Well-known belt conveyor systems consist of a conveyor belt that is threaded as an endless loop in the belt frame with a large number of support roller stations and one or more drive and deflection drums. This conveyor belt is set in motion by one or more drive drums with one or more conveyor belt drives at a defined conveyed material speed and is advantageously continuously operated at this conveyor belt speed.
  • belt conveyor systems which have frequency-related drives. Such frequency-related drives facilitate the starting and stopping processes considerably. Nevertheless, these belt conveyor systems are operated with a defined, constant conveyor belt speed in order to ensure the necessary throughput capacity, even in phases with a reduced conveying quantity or a variable conveying capacity.
  • the belt conveyor system consists of a large number of sections, such as trough areas, trough areas, vertical curves, horizontal curves, straight sections, inclines, inclines, etc.
  • these sections often have different carrier roller distances and, accordingly, different rolling resistances for the conveyor belt.
