Pre-Setting of Rotating Knives,
Granulator with Open Cutter
Knives can only be pre-set on granulators with open cutter.
The knives are pre-set on a jig.
The jig is not included when the
granulator is delivered, but is
a very practical accessory.
Setting Up the Knives
NOTE: The knives must be
sharpened before pre-setting.
When the machine is delivered, the jig is calibrated
against the set screws welded solid in the granulator cutter.
The jig gives the correct clearance of 0.008 - 0.012 in.
(0.20 - 0.30 mm).
• Screw the adjustment screws on a rotating knife in somewhat.
• Put knife in the jig, with the edge downwards.
• Put an 0.008in. (0.20 mm) feeler gauge between the adjustment screws
and the rear of the jig.
• Unscrew the adjustment screws
until the feeler gauge begins to bind.
• The pre-setting is now completed
and the knife can be installed in the cutter.
Installation of Pre-Set Knives.
NOTE: Each time the knives are changed, the
fastening screws must be replaced by new ones.
Install one pair of knives at a time.
• Clean the knife attachments.
• Install one pair of knives
• Install the attachment screws with washers loosely.
• Adjust the pair of knives against the outer edges of the cutter housing.
