The height positioning of the rotor (4) and thus the play between the wings (3) of the rotor and the sieve (5) of the machine are adjustable by means of an adjusting system (20-26), even during operation of the machine. The drive of the rotor (4) by a belt (19) allows to omit gears as well as an oil bath for the drive. The risk of a contamination of the granulated material by residues is thus obviated. The sieve (5) is supported on a retaining ring (6) which allows to adjust the height of the sieve in such a manner that the internal surface of the sieve is always at the same position independently of the thickness of the sieve. It is thus possible to adjust the play between the sieve and the rotor with precision.

[ I claim:] [1.] A granulating machine comprising,a rotor shaft;a casing around the shaft;a bearing between the shaft and the casing for supporting the rotor shaft for rotation with respect to the casing;a frame outside the casing;a sieve supported by the frame, the sieve having the form of a truncated cone narrowing downwardly;a rotor supported on the rotor shaft to rotate with the shaft and being disposed in the cone of the sieve for being rotated for granulating material in the cone of the sieve;a lateral driving element disposed laterally of the shaft and the casing, under the sieve and under the rotor and being in driving connection with the shaft for rotating the shaft, whereby the granulating machine is designed for in-line operation;a mechanically-operable axial adjusting device external to the casing and so connected with the rotor shaft for axially displacing the shaft and the rotor thereon with respect to the sieve by non-hydraulic mechanical means;an air-cooling system being provided for the rotor shaft, driving shaft, and bearings; andan indicator scale connected with the axial adjusting device for indicating the axial position of the shaft responsive to the axial adjusting device.
