Abstract: The present invention relates to a method for determining a section-related running friction resistance of the belt conveyor system that is in operation. The method comprises at least the following steps:
A) dividing the conveyor section of the belt conveyor system into “m” system-specific segments,
B) input of constant data at least with regard to the transport length of the belt conveyor system, the length of the segments and the incline or decline per segment into the evaluation device,
C) continuous recording of varying data at least with regard to the current conveyor belt speed and the drive power or the drive torque,
D) specification of determination data comprising at least a current material section mass and a segment-specific belt loading qm of the entire belt conveyor system based on the is measured material mass flow at the measurement point,
E) storage of the completely recorded varying data and the determination data in the evaluation device after each passage through a defined conveyor belt portion of the conveyor belt, wherein each passage is numbered with a consecutive index “j”, and
F) calculation of the load-dependent running friction resistance for each segment and the idling power of the belt conveyor system by the evaluation device by means of a system of equations using the constant data, the varying data and the determination data.-
