A method for controlling and / or regulation of a volume flow, of a bulk material or of bulk materials, in particular of mineral bulk materials, waste materials, of raw materials or of materials or apparatus for carrying out of the abovementioned method

摘要

A method for controlling and / or regulation of a volume flow (v.) of a bulk material (2) or of bulk materials, in particular of mineral bulk materials, waste materials, of raw materials or of materials, wherein a first and a second conveying means (3, 4) are provided, wherein the bulk material (2) the first conveying means (3) is supplied and the conveying speed (v₁) the first conveyor (3) can be controlled, wherein the bulk material (2) of the first conveying means (3) to the second conveying means (4) is transported and in this case a material - terminating edge (5) passes through, wherein the bulk material (2) with the aid of the second conveyor (4) is fed to a working machine and wherein the volume flow supplied to the working machine (v.) of the bulk material is essentially constant, and wherein the conveying speed (v₂) of the second conveyor (4) can be controlled, characterized in that, on the material - terminating edge (5) with the aid of a first optical measurement of the actual volume flow and / or the imminent material termination set is determined that, in the region of the second conveyor (4) the actual volume flow with the aid of a second optical measurement is determined, in the end region (3c) of the first conveying means (3) the material - terminating edge (5) and for this region is designed for the realization of a first optical measurement of a first laser - camera system (7) is provided and is arranged in accordance with that, in the region of the second conveyor (4) for the implementation of a second optical measurement of a second laser - camera system (8) and provided in accordance with is arranged, and that for the case that, in the case of the second optical measurement fluctuations in the volume flow in the central region of the second conveyor (4) to be determined, the conveying speed (v₂) of the second conveyor (4) is controlled such that these fluctuations in order to achieve the of the machine to be supplied to at the end, in particular to a terminating edge (9) of the second conveyor (4) to be discharged to the working machine is essentially constant volume flow (v.) then be correspondingly smoothed.
