Described is an apparatus and a method for transporting particulate material (2), said apparatus comprising a supporting surface (1) for supporting the material (2) to be transported and having a feeding end (5) and a discharging end (6), where the apparatus comprises a number of air ducts (7), which under an inclined angle relative to the supporting surface (1) and pointing in the direction of the discharge end (6) pass through the supporting surface (1) from below and open into a space (3) above the supporting surface (1), where at least some of the air ducts being connected to a high pressure air source (8) for intermittently injecting high pressure air into said space (3). The apparatus and the method are peculiar in that at least some of the air ducts (7) are constructed in such a way that portions of the material (2) to be transported is allowed to fall down into each of said air ducts (7) between injection of high pressure air through said air ducts (7). It is hereby obtained that the kinetic energy of the high pressure air to a much higher degree than by the known apparatus is transferred the material to be transported.
