Abstract: A method and apparatus for dewatering a mixture of granulate and water are disclosed. In accordance with one example of the system described herein, the apparatus includes a casing as well as hollow sieve body with side walls formed as a sieve, the sieve body being arranged in the casing and suspended thereto. The sieve body tapers towards the bottom, and a clearance is formed between the casing and sieve body. For delivering the granulate-water mixture an inlet is arranged in the upper part of the sieve body. A corresponding outlet for the dewatered granulate is located at the bottom of the sieve body. The inlet is arranged in the sieve body and the sieve is formed such that the water laterally escapes through the sieve into the clearance due to centrifugal and gravitational forces when passing through the sieve body from top to bottom.

Abstract: A granulating knife (6) is described for a knife head (5) of a granulating apparatus, wherein the knife body (8) forms a cutting edge (9) and a face (10) originating from the cutting edge (9). In order to improve the operational lifespan of the granulating knives (6) it is proposed that the face (10) is provided with a coating which is harder in comparison with the remainder of the knife body (8).

Abstract: A device is described for granulating plastic having a granulating head (1) and having a drivable cutter head (4), which cooperates with a perforated plate (2) and is arranged inside a housing (3), and which is movable along an axial guide made of guide spars (7) and guide sleeves (8), which are displaceable on the guide spars (7), and is attachable to the granulating. head (1) via locking units (9). In order to provide advantageous design conditions, it is proposed that the locking units (9) comprise latching wedges (11) mounted so they are displaceable transversely to the guide sleeves (8), which penetrate the guide sleeves (8) and the guide spar (7) in oblong holes (12, 13) in the locking position and are supported in the direction of the spar axis on one side on the guide sleeve (8) and on the other side on the guide spar (7).
