Reduced rate may be required for equipment access
Belt Inspection and Maintenance
Remove guards to inspect belts and sheaves.
Inspect belts for cracks, dry rot, or damage. If belts are sunk into sheave grooves past top of belt, belt needs replaced. Replace belts as needed
Sheave may also be worn out if NEW belts are too deep into belt groove
Gearbox and Bearing Inspection
Check all oil levels in gearboxes
Verify all gearboxes are tight on shafts
Check bearings on feed roll and mixer shaft by removing cover plates. Ensure the locking nut is still firmly against bearing. Bearing sleeve should not slip or slide on shaft.
Is grease inside bearing housing in good shape?
Adjust sealing Strip above feed roll on the back side. Gap should be 2mm or .075 inches. Adjust as needed.
This prevents product from falling behind the back side of the flaking rolls.
Verify that feed roll gate is parallel to feed roll. Adjust as needed.
Scraper and Cheek Plate Inspection
Check scraper for wear and alignment. Scraper should be making equal contact to roll across length of scraper. If scraper is worn down to scraper bracket, replace scraper or adjust if able to be done.
Check cheek plates for wear and alignment, Cheek plates should be aligned so that no product can flow around the sides of the rolls. Wedges need to be .010 from roll shoulders. No more than .020.
Flaking Roll and Roll Bearing Inspection
Internals inspection of Flaking Mill
Product guide plate should be adjusted to force product directly into Nip of rolls. Use a piece of flat bar to see visual alignment.
Check the disengagement path (Distance of cylinder stroke availability) of flaker cylinders. Adjust as needed.
Stroke amount can NOT be greater than 35 to 40mm. See page 4/55 - 4/59 of manual for assistance and measurements.
Inspect roll bearings for build up where excess grease is expelled from bearing house. This part of the bearing end cap should be facing down.
If fine adjustment rods are pulled all the way to the south, adjustment to safety stops will need to be made.
Pushing fine adjustment all the way north, turn the safety nut counter clockwise 1/4 turn to reset the fine adjustment.
Hydraulic System and Bearing Caps Inspection
Check hydraulic system for leaks. Repair as needed.
Check bearing caps and bolts for tightness on all roll bearings
Check brass end plugs to ensure they are tight.
Take a roll measurement every 6 inches using the Pi-tape. Record findings on roll or notepad. if measurements are (under .010 difference PASS.) (.010 - .015 FLAG) (.015< FAIL)
