Abstract

A device (1) for preheating of powder (12), especially metal powder, in immediate connection with the filling of a mould. The device comprises an inlet (7), an outlet (8), an outer tubular means (2) and, arranged in the outer tubular means (2), an inner tubular means (3). The tubular means (2, 3) are arranged relative to each other in such manner that a vertically throughgoing gap (4) is formed between the inner circumferential surface of the outer means (2) and the outer circumferential surface of the inner means (3). The circumferential surfaces constitute heating surfaces (5) so that a flow of powder (12) falling through the gap (4) is heated to a predetermined outlet temperature over essentially the entire cross-section of the gap.
