Screen Replacement Instructions
Important
• disconnect power to the granulator before servicing any component
•
fix the granulator to a workbench or other stable work area during maintenance
• wear gloves whenever working with the granulator or when handling the knives
Shut down the trim removal system and electrically lock out the motor and granulator.
Uninstall the trim removal system and remove both the inlet and outlet transition. Fix the
granulator, resting on its vibration isolators, on a stable flat work surface.
Remove the granulator hood (item 2) by removing the four (4) slotted brass screws and
four (4) Belleville washers. Lift the hood off the two (2) locator pins in the base (items 1
and 14), and put aside the hood lying upside down.
Loosen the two (2) recessed screen-securing setscrews (item 19) located on the discharge
side of the granulator.
Rotate the granulator onto its discharge flange.
Loosen the six (6) bottom remaining screen-securing setscrews (item 20). Back the set
-
screws out only enough to loosen or disengage the granulator screen (item 21).
Remove the screen (item 3) by rotating it out of its slot. If the screen will not rotate and/
or waste material has packed the slot, carefully tap the screen along the sides with a soft
brass or hard wood dowel to free it.
Clean all machined surfaces and the screen slot. Carefully install the new screen; the
screen sides should guide the new screen into place. The new screen should be seated
0,015” - 0,030” mm below flush on the discharge or rear edge of the base. Check to make
sure there is clearance between the screen and knife (VERY IMPORTANT).
Tighten all eight (8) (item 19 and 20) clamping setscrews to 20 in-lbs. of torque. Begin
with the screws on the outlet side, and tighten thereafter the screws towards the inlet side.
Remember to check, that the screen is still 0,015” - 0,030” below surface. Slowly (by hand)
rotate the rotor backwards. If the rotor knives do not clear the knife reset cutting clearanc-
es as outlined in Section IV (ONLY if the knives are new or re-sharpened).
Clean all mating surfaces of the hood (item 2) and base (item 1). Using the two (2) loca-
tor pins for proper alignment, place the cover onto the base making sure that the mating
surfaces are in full contact, without “rocking”. Fasten with the four (4) slotted brass screws
and Belleville washers. To avoid cutter distortion and rotor “rub”, only assemble covers to
bases with same serial number (hoods and bases must not be interchanged).
The hood fill (item 8) prevents the screen from rotating if the screws were not or improperly
tightened
