ABSTRACT:
An arrangement for supplying powdered material to a spraying device in an installation for thermal spraying comprises at least one powder storage container and an injection device by which the powder is introduced into a stream of carrier gas. A buffer chamber is disposed upstream of the injection device and comprises means for controlling the level of the powder, at least one controllable feeding means being connected, by means of a control device, to the level-controlled buffer chamber.
The present arrangement allows to obtain a well-defined rate of flow of powder which is constant and adjustable, from one or more powder storage containers.
