5-5 Removing and Replacing the Screen
Inspect the screen monthly for wear and cracks. Check the holes in the screen for
elongation. Turn the screens front to back monthly to even out the wear.
Avoid contact with the rotor knives, which are just above the screen. The
cutting edges are very sharp.
Removing the Screen
Use the following procedure to remove the screen:
1. Turn the main power off, remove the line fuses, and tag the machine as out of
service.
2. Unscrew the screen cradle interlock actuator screw with a box wrench or ratchet
wrench. Make sure the end of the interlock actuator screw is visible and clear of any
contact. When disengaged, the interlock opens the electrical control circuit to the
motor and prevents the machine from running.
3. Turn the screen cradle retainer bolts clockwise until they stop. Repeat on the screen
cradle retainer bolts at the rear of the machine.
4. Release the discharge transition toggle clamps to drop the discharge transition onto
its rollers. Push the discharge transition, on its rollers, all the way back out of
position. Engage the toggle clamps to hold the transition back while the cradle is
lowered.
5. Start the screen cradle hydraulic cylinders from the open/close control panel by
turning the selector s
witch to the “Lower” position and pressing the button in the
center of the switch. Hold the button until the cradle stops, and then release the
button and return the switch to the off position.
6. Remove the screen one segment at a time:
a. Remove the screen clamps (one per screen)
b. Grasp the screen on its near edge and raise the edge, allowing the screen to
slide in the cradle.
c. Pull the screen toward you slowly, allowing it to slide over the edge of the
screen cradle and then down onto the machine support bar.
Do not hit the rotor knives with the trailing end of the screen.
d. Ease the screen from the support bar to the floor and remove it from the
front of the granulator.
