Abstract

See full text

A powder conveyor has a pneumatically actuated dense phase powder pump and a pressure controller. The dense phase powder pump comprises at least one conveyor chamber having a powder inlet valve and a powder outlet valve. The pressure controller can be used to adjust and maintain a set pressure on the at least one conveyor chamber of the dense phase powder pump that is or can be previously defined and/or to adjust and maintain an actuation pressure on the powder inlet valve or the powder outlet valve that is or can be previously defined. The powder conveyor further comprises a gas flow detection device for detecting or determining a quantity of gas that is fed or removed per time unit when the set pressure is adjusted and maintained on the at least one conveyor chamber or a quantity of gas that is fed to the powder inlet valve or the powder outlet valve per time unit when the actuation pressure is adjusted and maintained. An evaluation device compares at least one detected or determined gas flow value with a corresponding set value and automatically generates an error and/or alarm signal when a deviation is detected.
