Plastics granulating device

Abstract

A device for granulating plastic melts comprises a granulating head (2) to which a perforated plate (3) provided with melt-discharge openings (10) is attached, which openings are swept by rotating knives (4). The perforated plate (3) is enclosed by a granulating housing (1) which is provided with at least one housing inlet (7) through which a cooling and transport medium (C), preferably water or air, can be supplied to the interior of the granulating housing (1), the cooling and transport medium (C) flowing with a motion component along the inner wall of the granulating housing (1) from the granulating head (2) toward a housing outlet (8) which is arranged in the end region of the granulating housing (1) opposite to the granulating head (2) and through which the cooling and transport medium (C) can be discharged along with the granules (G) produced. The rotating knives (4) are arranged in a knife holding device (6) mounted in a rotatable manner and coupled to the drive shaft (18, 18′) of a motor (9) via a magnetic clutch (15), hence being driven in a contactless manner.
