3-6 Initial Start-up
This machine has been run under power and tested at the factory prior to shipment. The
necessary settings and adjustments have been made so that a minimum amount of setting up
or re-adjustment is required when starting up the machine in its new location.
With all electrical, mechanical connections and lubrication requirements having been
attended to, the following start-up steps should be carefully carried out before attempting
to place any material into the infeed hopper. Use the following procedure to prepare the
machine for initial start-up:
Before operating the granulator, insure that the granulator has been correctly
assembled and wired.
1.
Check the interlock switches and zero speed sensor as describe in Sections 5-6 and
5-7.
2.
Check the screen as described in Section 5-5.
3.
Access the cutting chamber as described in Section 3-4.
4.
Thoroughly clean the rust preventative materials or grease from the hopper, the inside
of the cutting chamber, knives, rotor, screen, discharge system, and exterior of the
machine. Do not use solvent on any of the painted areas, as solvent may damage the
paint.
5.
Check all rotor knives to make sure they are properly seated on the rotor and securely
fastened. Although they are ground as a set, one knife will probably be .001” to .002”
higher than the others. This should be marked and used when adjusting the bed knives
for proper clearance.
6.
Use a feeler gauge to check the clearance between the rotor and the bed knives by
turning the rotor backwards. Rotating the rotor backwards gives a better feel and
does not cut the gauge, should the knives be too close. Check the knives on each
end only. Proper clearance is 0.15 mm (0.006”) to 0.20 mm (0.0008”). This clearance
is slightly greater at the center of the knives.
Note:
Recheck knife clearance after the first 24 to 36 hours of operation.
7.
To make the adjustment on the bed knives, the bed knife adjusting screws should be
hand tightened to hold the knife firmly against the knife seat while adjusting the
knife forward using push and pull screws. After the clearance is set, torque the
screws to 640 Nm (472 ft. x lbs.).
Note:
All screw tightening torque figures are for un-lubricated thread conditions. All
Screw threads must be clean of any residue before installation to prevent galling
8.
With the exposed parts of the machine thoroughly clean, and all knife clamping bolts
securely fastened, close the cutting chamber as described in Section 3.5.
Note:
After initial start-up, the rotor knife retaining screws should be
checked after 8 hours running to be assured that 640 Nm (47 ft. x lbs.).
Of torque is maintained. Thereafter, rotor knife retaining screws
should be checked weekly.
Note:
The rotor must be rotated at least two rotations every 30 days to
prevent brinnelling and corrosion of raceways.
