ABSTRACT:
The invention is directed to a device for converting free-flowing feed material by pressurization with a cylindrical compression chamber arranged around an axis and confined at its periphery by a ring element with passage openings, and accommodating a pressure element that rotates around the axis in the direction of rotation. The feed material is axially conveyed to the compression chamber and is radially supplied to the ring element by the pressure element. The pressure element includes at least one pressing blade, which extends to and interacts with the ring element, the front flank of said pressing blade in the direction of rotation being curved such that between pressure arm and ring element, a narrowing compression zone is formed, the end of which is formed by a pressure piece.
