Summary "Dust Conveyor and Method for Operating a Dust Conveyor" The invention relates to a dust conveyor (100) having a pneumatically actionable dense phase dust pump (1) and a pressure regulator (91). ). the pneumatically actuated dense phase dust pump (1) comprising at least one conveyor chamber (4) having a dust inlet valve (7) and a dust outlet valve (8). pressure regulator (91) may be used to adjust and maintain a preset pressure in at least one conveyor chamber (4) of the dense phase powder pump (1) which is or may be pre-defined and / or to adjust and maintain a set pressure on the dust inlet valve (7) or dust outlet valve (8) that is or may be preset. According to the invention, the dust conveyor belt further comprises a gas flow detection device (d1, d2, d3, d4) for detecting or determining the volume of gas is fed or removed per unit time when the set pressure is adjusted and maintained over at least one conveyor chamber (4) or a volume of gas that is fed to the dust inlet valve (7) or dust outlet valve (8) per unit time when the drive pressure is adjusted and maintained. an evaluation device (92) compares at least one detected or determined gas flow value with a corresponding fixed value, and automatically generates an error and / or warning signal when a deviation is detected.
