c. Check the gap of mill rolls is consistent from end to end. Put the 60g/m^2 (16 Bond)
paper into the space between two rollers, turn the fast roller to pass through the paper.
Then you can calculate the evenness of the interval between two mill rollers by
observing the distribution of indentation. Measure three times, and take the average. If
the length of paper is 100mm, and the width of paper is 0.9 times the length of mill roll,
you can make adjustments automatically by turning the hand wheel and observing the
indicator.
Inspection of No-load rotation
a. Running the motor to check the rotation direction of the belt pulley is correct, and
check if the rotation speed can meet the requirement.
b. Check whether there are knocking sound and other unusual conditions.
c. Check whether the bearing and other parts are under the normal running status
d. No-loading check should be done at least 30 minutes.

5.4 The operation of machine
a. In order to ensure the raw material can't fall into the crushing cavity at will, you should
close the gap of the feed hopper.
b. Start the motor.
c. Put the raw material into the feeding hopper.
d. Adjust the knob of the adjusting plate slowly, check whether the crush degree can
meet your requirements. You can fix the hand wheel when the crush degree of raw
material can meet your requirement by using the lock nuts.
e. After the end of work, the machine should be run at an idling condition for 1 min to 2
min. The machine should not be stopped until the materials that remain inside the
machine are fully discharged.

In order to keep the mill in a serviceable condition and extend the service life, you
should regularly make adjustments and maintain the mill. The operator should be
familiar with the concepts and the procedure to adjust and maintain the complete
machine and it’s parts.
6.1 The adjustment of flow (please check table 1)
Because the crushing degree is different, the gap of feeding hopper can be adjusted to
ensure uniform feeding at any time. The method of adjusting the flow is to revolve the
knob on the regulating mechanism. The width of the feed opening will change when you
revolve the knob, and the inflow volume of raw material is likely to change. When you
need to adjust the flow, the adjustment of the gap between the rollers also should be
adjusted at the same time.
6.2 The adjustment of the gap between the rollers (please check table 1)
1) The initial adjustment before running the machine
The gap between mill rollers should be adjusted to 0.4-0.8mm before the whole
machine leaves the factory. If there is a little change during shipping, the user can check
the gap by visual inspection, or check the gap with a feeler gauge. If the gap is
inconsistent, you can loosen the locknut, and rotate the left and the right hand wheel
according to the rotation direction identification. You can fasten the locknut when the
gap between the rollers is consistent.
2) The adjustment after running the machine
After running the machine, put the 60g/m2 paper into the space between two rollers,
and turn the fast roller to pass the paper through. Then you can calculate the evenness
of the interval between the two mill rolls by observing the distribution of indentation.
Measure three times, and take the average. The length of paper is 100mm, and the
width of paper is 0.9 times the length of mill roll. You can tighten the nut if the
unevenness of the interval is too large. Turning the left and right hand wheel according
to the indication of the handwheel dial and the rotating direction identity . Keep the
uniform evenness, then put the raw material into the feeding hopper. Rotating the

adjusting mechanism of the adjusting plate according to the size of the final products.
Revolving the left and the right hand wheel while adjusting the flow control knob.
Adjusting the interval between the mill roller, and the smaller interval is adjusted, the
smaller size of final products you will get.
Notes: The left and the right hand wheel should be adjusted at the same time, and
they should have the same number of the circles, or the interval on both sides of
the mill roller will not be uniform.
You can fasten the locknut to enter the normal working state when the size of the final
products meets your requirements. In order to adjust the machine quickly, you can write
down the data for your reference.
Regarding 4 roller, 6 roller and 8 roller combination malt crushers, they have the same
adjustment method as the 2 rollers malt machine.
6.3 The adjustment of wallboard (Please check table 1)
Wooden or Nylon wallboard is installed on the inner wall of the crushing cavity on both
sides of the mill rollers, to prevent the raw material from leaking from both ends of the
rollers. When the diameter of the mill rollers becomes too small, you should loosen the
clamp nut of the wallboard, and move down the wallboard. You can fasten the clamp nut
if there is no raw material left in both ends of the rollers.
7. The maintenance, replacement and demounting of the mill
roller
