2. Do not run the mill when the protective cover is improperly attached. The protective cover is not allowed to be opened or removed
while running the machine. The protective cover should be repaired and replaced before operation if it is damaged.
3. Check and replace worn-out or broken parts before operating.
4. Any lubricant contamination needs to be cleaned before use.
5. Check the tightness of the drive belt and the reliability of the protective cover, and check whether there are any loose fasteners.
Ensure the parts are well lubricated.
6. Check the gap of mill rolls is consistent from end to end.
INSPECTION OF NOLOAD ROTATION
A. Run the motor to ensure the direction of the belt pulley is correct.
B. Check if the rotation speed meets the requirement listed in the chart above.
C. Ensure there are no knocking sounds or any unusual conditions when inspecting.
D. Ensure the bearing and other parts are under the normal running status.
E. Please complete a no-loading check that should be done within 30 minutes before running the machine.
ADJUSTMENT OF FLOW
Because dierent products are dierent sizes and need dierent levels of crush, the gap of the feeding hopper can be adjusted to ensure
uniform feeding at any time. The method of adjusting the ow is to revolve the knobs on the regulating mechanism. The width of the
feed opening will change when you revolve the knobs, and the inow volume of raw material is likely to change. The gate in the hopper
is opened and closed to adjust the ow rate as desired for the process.
ADJUSTMENT TROUBLESHOOTING
A. The left and the right-hand wheel should be adjusted equally in order to keep the rollers parallel. Ensure the wheels are turned the
same number of times or the gap on both sides of the mill roller will not be uniform.
B. You can fasten the locknut to enter the normal working state when the crush meets your requirements. Record the data for quick
adjustments.
GENERAL MAINTENANCE

6. If maintenance is needed, ensure the mill is disconnected from power.
7. Stop the machine before removing the pulley cover. If absolutely necessary, you may run the motor briey. Then stop the machine and
reinstall the cover before actual use.
MAINTENANCE, REPLACEMENT, AND REMOVAL OF THE MILL ROLLERS
The correct installation, maintenance, and diagnosis of the mill rollers will increase the performance and service life of the mill. After using
the mill for a period of time, you will need to maintain and adjust the mill according to the following methods.
1. Removal of the mill rollers
a. Remove protective cover, V-belt, and V-pulley.
b. Remove the small and big wheel gears.
c. Remove the adjusting mechanism.
d. Open the bearing block and remove the mill rollers
2. Installation of the mill rollers is the reverse of removal before Reassembly, you should clean the surface of the parts, lubricate the
bearing, check the V-Belt for damage, and ensure the roller rotates smoothly. Check whether there is dust and/or impurities on the
mill roller bearing block. If not it will aect the grinding eciency of the mill.
Maintenance of the Mill Rollers
A. To maintain the longevity of the mill, ensure the raw material is clean and free of debris.
B. Do not bump and damage the journal when you carry, install or disassemble the mill roller.
C. To protect the mill rollers, do not roll them on the ground or slab. Doing so can damage the roller grooves.
Cleaning the Mill Roller
Keeping the mill rollers clean is very important. Please keep the surface of the mill rollers clean when you mill raw materials. A mill brush
(or sti nylon brush with a long handle) is the most common tool to clean the mill roller. When cleaning, keep enough pressure on the
brush to ensure the mill roller is cleaned from any debris.
A. Do not force the adjusters closed. The closing force should be light and even so as to not damage the adjusters and rollers.
B. Do not allow nails, metal, or hard rock mixed with abrasives to enter the mill. If it does, the mill will be damaged.
C. Do not let the mill idle unattended. Letting the mill idle unattended can allow the adjusters to close the gap. This will air grind the
rollers and damage the mill. To avoid air grinding the rollers, the hopper should be ready with a small amount of material (for example,
grain) and the gate opened.
D. This machine mainly is designed to crush malted material. When grinding corn, a coarser grinding roller is required. It can also be used
to remove the germ and then crush it into a ne powder as a processing method.
E. This machine is not designed to process soybean and high oil content material.
LUBRICATION OF THE MILL
1. The lubrication of the rolling bearing block, (please see Table 3)
NOTE: Unpack and wash regularly and apply enough lubricating grease.
2. Regularly lubricate all frictional parts with food-grade machine oil such as CRC Machine Oil: Mineral.

5. This machine should be repaired in a timely manner when a failure occurs, running with problems can cause permanent damage to
the mill or injury.
The Adjustment of The Bae (Please Refer To Table 1)
A Wooden or Nylon Bae is installed on the inner wall of the crushing cavity on both sides of the mill rollers. This helps to prevent the
raw material from leaking past both ends of the rollers.
When the diameter of the mill rollers becomes too small from wear, loosen the clamp nut of the wallboard, and move it down. Re-fasten
the clamp nut when there is no raw material left on both ends of the rollers.
GAP ADJUSTMENT
Barely diers in size, requiring dierent levels of crush based on the size of the barely. This requires adjustments be made to the mill gap.
If you mill too course, it will negatively impact your eciency. Milling too ne can result in a stuck mash. Proper adjustment is critical to
quality wort production. The gap of the mill rollers can be adjusted to ensure uniform milling. To adjust the gap, revolve the large knobs on
the front of the mill, the knobs will adjust the width of the feed opening to a larger or smaller gap depending on the direction you revolve
the knobs. NOTE: The ow rate of raw material is also likely to change.
Method 1 — Feeler Blade
A. Disconnect power to the mill and lockout.
B. Pass a feeler gauge between the rollers at both ends.
C. It is important that the rollers remain parallel.
D. Set the gap to .032 by adjusting the hand wheels. The mill is marked for opening and closing the rollers.
E. Mill a sample of barley and analyze.
F. Adjust as needed.
Method 2 — Sieving Barley
A sieve analysis (or gradation test) requires a set of US standard test sieves. (not included). Once the mill gap is initially set by a gap
measurement a sieve analysis will ne-tune the gap to your lot of barley.
1. Place three rubber balls on each of the US standard test sieves #14, #30, and #60
2. Place the bottom pan under the #60 test sieve. They must be stacked in the proper order with the widest screen being on top (#14)
and the nest (#60) on the bottom above the pan.
3. Weigh 100 grams of the milled grain sample.
4. Place the grain into the top sieve
5. Put the lid on.
6. Place the sieves on a smooth surface.
7. Slide the test sieves back and forth for 3 minutes.
a. The sieves need to travel 18” in one direction and then the other, taking 0.5 seconds each way for a total cycle time of 1.0 second.
Every 15 seconds you tap the sieves and pat downward on the working surface.
b. Maintain this pattern for 3 minutes total.
10. Empty each individual sieve, being sure to brush them out completely, then weigh and record the results.
11. Calculate the percentage for each sieve by dividing each fraction by the sum of all fraction weights then multiply by 100.
Example: #14 + #30 + #60 + Pan = Sum then X / Sum * 100 = percentage.
Since we are using 100 grams of sample material, the percentages will be very close to their original fractions.
#14 #30 #60 Pan Max eciency
Trouble-Free 75–80 10–20 <10 <5 95%
Practical 45–55 20–25 5–15 <7 98%
Industrial 30–35 40–60 5–15 <10 100%

TROUBLESHOOTING
Method 3 — Paper Method
Put 16 Bond paper into the space between the two rollers and turn the fast roller so that the paper can pass through. Once the paper is
passed through, you can calculate the evenness of the interval between the two mill rollers by observing the distribution of indentations.
1. Disconnect power from the mill.
2. Cut a piece of paper 4” long with a width of 0.9 times the length of a mill roll.
3. Feed through the gap while turning the rollers by hand.
4. Measure the indentation three dierent times and take the average of the measurements.
5. Adjust the gap till the thickness is even across the length of the paper.
To test, put the raw material into the feeding hopper. Adjust the gap according to the crushing requirement. Rotating the left and the
right-hand wheel and adjusting the ow control knob.
