Patent ID: 7007559

Claim:
A method of setting a pre-setting, by which blades of a granulating head carried by a shaft which is driven by a motor and which is displaceable in the axial direction of a granulating device abut against a perforated plate through perforations of which the material to be granulated is supplied wherein use is made of the torque of the motor for this setting, characterized in that the shaft is adjusted at a constant speed in both axial directions in succession, wherein the pattern of the torque of the motor is recorded over the displacement path for both directions and the differential ⅆ M ⅆ x is formed from this, in which x represents the displacement path of the shaft, the position x 0 of the shaft is then determined for ⅆ M ⅆ x = 0 , and finally, starting from the position x 0 a position x =x 0 +x z of the shaft is set, in which x z represents the desired advance of the shaft in the direction towards the perforated plate.
