PROBLEM - WHOLE GRAIN COMING THROUGH MILL
1
POSSIBLE CAUSE - Improper setting of rolls. Roll spacing too wide.
SUGGESTED REMEDY - Rolls should be set closer together to crimp all grain being processed.
2 POSSIBLE CAUSE - Overfeeding the rolls.
SUGGESTED REMEDY - If the grain hopper gate is open too wide, the rolls will not take all the grain. The grain can
build up above the rolls. This causes whole grain to overflow the rolls and escape being crushed. Reduce feed rate to
minimize grain overflow. This should not happen while using Rubber Baffles - Ref. No. 16, Page 17.
3 POSSIBLE CAUSE - Uneven kernel size.
SUGGESTED REMEDY - The problem may only be that a few small, poorly developed whole kernels going through
the mill. It is better not to set the mill to crack these if in doing so you would “over-roll” the majority of the kernels.
4 POSSIBLE CAUSE - Improper spring tension.
SUGGESTED REMEDY - Refer to factory recommendations regarding spring tension. See page 8.
5 POSSIBLE CAUSE - Rolls out of alignment.
SUGGESTED REMEDY - Realign rolls. See page 8.
6 POSSIBLE CAUSE - Baffles between rolls and hopper have too much clearance.
SUGGESTED REMEDY - Remove hopper and adjust baffle by bending material so clearance is less than 1/8 inch.
Rubber baffles will “sing” for a while, but will quiet down after a few minutes.
PROBLEM - DISCHARGE AUGER SEEMS TO SLOW DOWN WHEN PLACED UNDER A LOAD
1
POSSIBLE CAUSE - Excessively wet or finely processed feed.
SUGGESTED REMEDY - The higher the moisture content, and the finer the feed material, the more power required
to convey it through an auger. Adjust hopper gate to keep grain flow at a level where optimum auger speed and feed
flow can be maintained. Check the tension of the v-belt that operates the auger base.
PROBLEM - HIGH PITCHED SOUND FROM RUBBER BAFFLES
1
POSSIBLE CAUSE - Baffles are touching the rolls when they leave the factory by design.
SUGGESTED REMEDY - Continue running the mill and when the rubber baffles wear a little, the sound will decrease.
