To prepare for replacement, contact us for a set of replacement hammers. Each row of hammers is wired into a specific order and balanced as a set at the factory. You must maintain the order of the hammers and this balance as you make changes. 如果你不這樣做, the unbalanced hammers can cause excessive vibration.
For Rotation: Follow steps 1 – 11 下面, and rotate the stack of hammers to use a fresh striking edge before completing steps 12-15.
For Replacement: New hammers are delivered in groups marked 1 自 8. Place the new hammers for Group 1 into Row 1, as described in Steps 12-15.
Steps:
- Switch off the main power supply breaker.
- Secure the main switch using your site’s OSHA-approved lockout/tagout procedure.
- 打開磨機護罩.
- Start with the first row
- Remove the collar from one end of the row.
- Pull out the rod and, as each hammer is released, remove the hammer.
- Stack each hammer in the same order as on the rod.
- Inspect the rod.
- If you see excessive grooving on the rod, replace the hammer rod.
- If you are replacing the hammers, you should also replace the hammer rod.
- Start with Row 1. Insert one hammer between every other disc . (Some rotors use 2 hammers between each disc.)
- Insert the hammer rod to hold the hammer in position.
- Insert the next hammer and continue until all hammers for Row 1 are in place.
- Lock the rod, using the collar or cotter pin in the end of the rod.
- On Row 2, stagger the hammers between the discs opposite Row 1.
- Continue installing the hammers on the rods, working around the rotor in numerical order from Rows 3 through 8.
- After all the hammers have been re-installed, rotate the rotor by hand to ensure there are no catches.
- Close the mill hood.
