Custom Mounting Solutions:
See the attached drawing for mounting your mill on a custom stand, cabinet, or grain handling system.
The bolt pattern is the same for the top and bottom of the mill. Use M6x1 hardware for mounting the mill
or custom hopper or grain handling equipment. Ensure there is at least 10mm (7/16”) of the bolt engaged
with the threads. For example, if you are mounting to 3/4”plywood (19mm), use at least 30mm long bolts.
Temporary thread lock applied to threads is acceptable if preferred.
Sticker installation and instruction:
Place the included gap setting sticker on the adjustment side of
the mill. There are 3 types of malt listed for you. The .055” gap is
the setting that produces a proven “Normal” rating crush with
fresh two row barley. See the calibration instructions for how to
determine this gap setting. Document your preferred setting on
the space provided for your records. Use the other open spaces
for your own preferred gap setting for other grain.
Gap Calibration:
Warning: Moving parts can crush and cut. Do not operate the mill without hopper and guard
installed. Unplug or lockout device before servicing.
Ensure the unit is un-plugged, and the guard is removed before
proceeding. Included with your grain mill is a calibration plate
to be used for finding the proper gap setting that produces
an ASBC “normal” grist crush. You will be able to produce a
“normal” crush at 0.055” (1.4mm). The Blichmann mill operates
with synchronized rollers with a large diameter which does
not require a close gap to produce a desirable crush. To set the
mill at this gap, pull the adjustment knob and rotate clockwise
to the widest setting (18). Insert the plate into the top of the
mill between the rollers. Pull the adjustment knob and rotate
counterclockwise until rollers contact the gap tool. Document
this number with permanent marker on the label provided.
Measure the performance of the mash and make small gap
adjustments to the gap setting if needed to improve efficiency
without sacrificing sparge and recirculation rates.

Stand Assembly:
The Mill has an optional stand available in two different sizes. Each are assembled in the same order. Only
tighten fasteners finger tight until the entire assembly is put together. Adjust the straightness of the stand
and then tighten each fastener no more than 1/8 turn past tight.
Tools Required:
10mm Combination Wrench
17mm wrench (Casters)
9/16” wrench (Feet)
Insert and press fit the 8 long the carriage bolts into outside holes of the top
board and lay the board down with the screw threads facing up. (Figure 1)
Install the four leg mount angles with the large washers and nuts. (Figure 2)
Install the legs and attach the 3 leg braces. The front of the board is the edge
closest to the hole. Don’t install a leg brace on the front of the stand, see
diagram for designation. If using the feet attach the feet to the legs now.
(Figure 3)(Figure 4)
If you are using a caster kit, attach the large board to the stand using the
casters and hardware. Lock the caster to keep the stud from spinning during
installation. (Figure 5)
Do not install chute until the mill is installed
Install the canvas grain chute as shown. Note that one edge is longer than
the other. (Figure 6)

Hopper Assembly:
After the mill is mounted, assemble the hopper as shown. Only use the nyloc insert nuts provided with the
Philips head screw.
Tip: Do not tighten the screws until the hopper is assembled and in place on the mill. Hopper panels labeled
“A” are for the left and right side, and panel“B” is the front or back. Panel“A” will be screwed to the outside of
the flanges on panel “B”. Install the hopper onto the mill with the M6 x 1 x 12 screws (the 4 shorter screws).
Tighten the all the screws and install the finger guard “C”.
Mounting the Mill:
Mount the mill to the stand with the motor switch facing forward toward the large opening on the stand.
Use the M6 x 1 x 30 screws (the 4 longer screws).

Operation:
Warning: Moving parts can crush and cut. Do not operate the mill without hopper and finger guard in-
stalled. Unplug or lockout device before servicing.
Adjust the gap setting knob to the desired setting. Fill the hopper and select “FWD”. You may stop the mill at
any time and restart as required.
Caution: Do not reverse direction of the mill without letting the mill come to a complete stop. This may
damage the gear drive over time. Always let the mill come to a complete stop before changing directions
from forward to reverse or reverse to forward.
The “REV” selection is only required to clear the mill in the event of debris or a gap setting is adjusted too
narrow. If the mill stops running, turn off the mill, unplug the device, and remove all the grain from the hop-
per. Verify that there is no debris wedged in the mill and adjust the gap to the widest setting (18). Verify that
mill operates without any grain, reset the gap setting to the desired crush setting and continue to mill grain.
Toolless Gap Adjustments:
With the mill set to the off position, pull the Knob until the pin clears the selection plate. Rotate the knob
Clockwise for a wider gap setting and counterclockwise for a narrower setting. Each setting on the position
plate adjusts the gap approximately 0.005” (.13mm). The wider spacing between some settings on the posi-
tion plate adjust the gap the same distance because of the behavior of an eccentric adjustment system.
