Installation and Start-Up
ROTATION
Counter-clockwise
when facing the
outlet port.
See Figure 3. The mill is shipped from the factory with the inlet port as
shown in Position 1. For convenience, the inlet port can be relocated
to any of the other three positions (see Disassembly Procedure). If
Position 4 is used the calibrations at the pointer will be upside down.
We suggest the use of a mirror.
The mill is equipped with a face type seal which must be water
cooled. The IN and OUT ports for introducing the water to the seal
are located in the gland.
NOTE: These are 1/4-inch pipe nipples, but the IN hole is smaller
than the OUT hole to prevent over-pressurizing (Figure 4).
The IN port must be used and the ow of water must be throttled to
produce a ush of 0.125 to 0.25 gpm (0.47 to 0.95 l/m). Flows in
this range provide safe cooling without damage to the lip seal.
Recommendation: use a solenoid valve in the water line to turn on
the water simultaneously with the mill. If the solenoid valve is not
used, turn on the water ush line before starting the mill.

Overhead equipment
Wiring
Rotation
Follow accepted engineering practice when connecting the inlet and
outlet with the overhead equipment, piping, or tubing. Use hangers
to eliminate any weight, stress or strain on the mill. Remember, if a
direct connection is made with any overhead tank, install expansion
joints in the line. This will prevent mechanical loads on the mill which
would damage it or a󰀨ect its operation.
3 Phase, 60 Cycle, 230-460 Volts. Follow the wiring directions on
the motor. Check the direction of rotation.
The rotation direction is counter-clockwise when facing the outlet
port. If run clockwise, the rotor retaining nut may back o󰀨, resulting
in damage to the mill.

The mill is shipped with oil in the bearing case. The level should be
checked at the oil level hole and if necessary, oil should be added
through the oil ll hole.
Use Mobil oil DTE BB ISO Grade 220 R & O (Rust inhibited) gear
oil. If DTE BB is not available, use S.A.E. 40 non-detergent mineral
oil. The mill is shipped with a solid cap screw in the oil ll hole. This
should be removed and replaced with the breather cap which is
wired to the mill.
Frequency of lubrication is dependent upon temperature and moisture
conditions. If the room temperature is normal, 70° to 80° F (21° C
to 27° C), and water does not contact the bearing case, change
the oil every 240 operating hours. When the temperature varies
from hot to cold or the mill is ushed out with water, condensation
will occur in the bearing case, requiring more frequent oil changes.
Normal operating temperature of the bearing case is 170° to 190°
F (77° C to 88° C).

The inlet and outlet ports are 2 inch sanitary male threads. The
inlet port is located in the body—its position can be changed. (See
Figure 3 on page 8.) The outlet port is located in the cover of the
mill. The mill must be fed with a pump; a Waukesha Cherry-Burrell
brand positive displacement pump is recommended. The capacity
of the mill is 6.7 to 33.3 gpm (25 to 126 l/m).

4. Remove the cover capscrews and pull o󰀨 the cover, then
remove the O-ring.
5. Pull the stator o󰀨 the studs and remove the O-ring.
In some instances the unit can be cleaned by ushing water through it
while the mill is in operation. However, some of the water will remain
in the bottom of the cone-shaped stator. If this is not acceptable,
dismantle the unit for cleaning.
1. Remove the “T” handles.
2. Back out the knurled lock screw.
CAUTION
Handle all parts carefully to avoid nicks and
scratches which will be detrimental to the operation
of the mill.

3. Pull the cover/stator assembly outward.
NOTE: You will experience some resistance to the stator
movement due to friction from the O-ring.
As soon as the O-ring is free, the cover and stator assembly can
be easily removed. It is not necessary to remove the adjusting
ring. Disassembly to this point allows complete drainage.
NOTE: To prevent wearing of the faces between the adjusting
ring and stator, lubricate these surfaces occasionally with an
approved silicone-type lubricant.

CAUTION
1. Apply a suitable lubricant to all O-rings and insert them in their
respective grooves.
NOTE: Place the seal seat O-ring over the seal seat and then
insert the seat into the rotor.
2. Follow the disassembly procedure in reverse order to com-
plete assembly. Torque the rotor nut to approximately 75 ft-lb
(102 N·m).
3. The seal water to the mill must be connected to the gland
connection marked IN (the ports are stamped “IN” and
“OUT”). The inlet of the gland contains the smaller (1/8”) hole.
The outlet contains the larger (1/4” hole). (See Figure 19).
The mill can be adjusted to have a clearance between the rotor and
the stator from a minimum of 0.010” (0.254 mm) to a maximum of
0.240” (6.1 mm), in increments of 0.001” (0.025 mm).
The body and the adjusting ring are calibrated as a unit and serialized;
they must not be interchanged with other Waukesha Cherry-Burrell
brand Colloid Mills.
The stator is held rmly against the adjusting ring by “T” handles
(Figure 21).
Adjust the clearance between the rotor and stator by turning the
adjusting ring counter-clockwise (when facing the outlet port) to
increase the clearance, and clockwise to decrease the clearance.
The adjusting ring is engraved with numerals indicating the clearance
in increments of 0.010” (0.254 mm). The indicator pointer indicates
the desired clearance. For setting in between the increments of
0.010” (0.254 mm), the drill point spacing is equal to 0.001” (0.025
mm) clearance. The drill point spacing coincides with the locking
hole spacing. There are 18 locking holes in the ring, spaced 20°
apart (Figure 20).
Rotating the ring by 20° (hole to hole distance) changes the milling
clearance by 0.001” (0.025 mm).
Example: to obtain 0.014” radial clearance, locate the 0.010 punch
mark under the pointer. Turn the ring counterclockwise four additional
drill points (or locking holes), and lock it in place with the knurled lock
screw (Figure 20). Tighten the “T” handles to rmly hold the stator
against the adjusting ring. The clearance will be 0.014” (0.36 mm).
Adjust the lock bolt and tighten the nut (Figure 21).
