Grain too Fine or
Dusting of Grain
Loose Sprockets

Troubleshooting
CAUSE
1. Overfeeding with excess
grain continually sliding
off top of rolls creates
friction and excessive roll
wear.
2. Crushing abrasive
materials other than
grain.
3. Foreign matter, such as
metal, going between
rolls.
4. Gravel in grain.
1. Uneven flow of grain into
mill.
2. Excess RPM
1. Improper setting of rolls.
2. Over feeding.
3. Uneven size kernels.
1. Overload on mills.
2. Opening grain control
gate too fast and too far
open.
1. Grain between rolls.
2. Low Voltage
1. Over rolling.
2. Rolling mixed grain.
3. Failure to reset rolls for
different varieties of grain
4. Very dry grain,
particularly when hard.
1. Set screws loose.
2. Loose chain
Keep rolls "hungry". Adjust control gate to feed in only amount of grain rolls
will take away. Usually overfeeding is not the cause for roll wear on deep-
grooved rollers.
Mills are designed to be used only on grain or similar textured materials.
We recommend a magnetic trap to remove steel or iron from the grain.
Sand and small gravel is difficult to remove from grain because of similar
sizes as grain. Larger gravel and small rocks can be removed by screening
with wire hardware cloth on frame mounted in hopper.
Eliminate "surging of grain" into mill as much as possible.
Recommend operation 900 to 1,000 RPM.
Rolls should be set closer together to crimp all grain being processed.
Grain control gate opened so wide rolls will not take all grain and builds
up above rolls. This can cause some whole grain to go over top and not
between rolls.
This could be reason for a few small, poorly developed whole kernels going
through mill. It is better to not set mill to crack these if in doing so you would
"over-roll" the majority of the kernels.
Running damp, high moisture grain can cause "sticking to the rolls," and
cause an abnormal power requirement on new mills. There sometimes can
be some sticking of dry grain to new rolls, particularly on oats and barley.
This condition should not continue after 200-300 bushels of grain has been
run.
Always open gate slowly and open only as far as necessary to keep rolls
"hungry". Don't overfeed rolls and cause an excess building up of grain in roll
pocket between rolls.
When grain is between rolls, separate rolls to allow grain to fall through
or turn rolls backwards and scoop out grain by hand. The best remedy is
to make a practice of closing gate before stopping mill so no grain is left
between rolls.
On electric motor driven units, check line loss for low voltage.
Open control gate to allow more grain to feed into rollers or readjust spacing
of rolls.
If mixed grains of different sizes are run together, to crack or crimp the small
grain, the rolls "over roll" or pulverize larger kernels in mixed grain. As a
general rule, all grains should be rolled separately and then mixed after
rolling.
Always reset rolls every time a different grain is to be processed.
Open rolls wider than normal to eliminate over-rolling. On extreme cases,
grain can be tempered by sprinkling a small amount of water over grain to be
rolled and let stand 8 to 12 hours. This is generally done in small holding bin
or wagon. The amount of moisture used depends on dryness of grain.
Check set screw first time mill is operated.
Keep chain in snug running condition by shifting idler.
