Sterling BP1018, BP1012 installation manual Removal and Replacement of Rotating Blades

Page 38

8.Install new or sharpened bed knives on each knife seat, making sure that the rotor is blocked to prevent it from rotating while installing each knife. Be sure to place the bed knives in the correct positionsthe rear (down stroke) bed knife must be placed with the extended cutting edge on top, and the front (upstroke) bed knife should be placed with the cutting edge on the bottom.

9.Replace the upper shields in position above the bed knives. The shield on the rear (down stroke) bed knife should be positioned so that the inside edge is set back approximately 1/32” from the cutting edge below it.

10.Before re-installing the knife bolts, wipe them clean with a lightly oil-damped cloth. Do not leave an oil film on the bolt since lubrication can adversely affect the stress on the bolt when torqued to the specified values. It is recommended that the knife bolts be replaced with each new set of knives. This will reduce the risk of bolt failure due to overstretching. Always use the specified replacement bolts.

11.Tighten the bed knife bolts at each end of the knife just enough to keep the knife in place, while still allowing the adjusting screws to move the knife forward. The remaining bolts can be left hand tight until the knife is adjusted.

12.Adjust the knife gaps with the rotor knives and close the machine, following Steps 8-14 in Section 6-4.

6-6 Removal and Replacement of Rotating Blades

NOTE: A qualified operator / maintenance mechanic should perform this operation. Protective gloves must be worn to avoid injury when handling the cutting knives.

To remove and replace rotor knives, complete the following procedure:

1.Open the granulator by following Steps 1-5 in Section 6-3.

2.Open the rear-closing panel by releasing the locking latch.

3.Pivot the in-feed hopper completely back to gain clear access to the cutting chamber, and clear any process material or foreign objects from between the knives.

4.Rotate the rotor so that the knife bolts are in a convenient position to remove the bolts with the appropriate wrench. Using a wooden block, block the rotor to prevent it from rotating while removing knives or after a knife has been removed.
