Colloid Mill Troubleshooting

Inlet

Outlet

Figure 6 

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 fill 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 fill hole. This 

should be removed and replaced with the breather cap which is 

wired to the mill.
Frequency of lubrication is dependent upon tempera ture 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 flushed out with water, condensation 

will occur in the bearing case, requiring more frequent oil changes. 

Normal operating temperature of the bear ing case is 170° to 190° 

F (77° C to 88° C).

Colloid Mill Troubleshooting

Problem

Likely Cause

Solution(s)

Seals leaking

Exceeding 150 PSI pressure 

limitation of pump

Open up gap reduce pressure

Seal flush water improperly 

plumbed

Connect flush water to IN/OUT ports as 

stamped on gland

Water pressure too high

Adjust to 0.125 to 0.25 gpm (0.47 to 0.95 l/m)

Seals misaligned on pin

Re-align seals to proper fit.

Noisy operation / 

Excessive power draw

Loose rotor nut causing rotor to 

stator contact

Tighten nut to 75 ft-lb.  

Check mill rotation (counterclockwise facing 

outlet port)

Inconsistent milling 

results

Loose adjusting ring

Set gap and tighten knurled screw in hole. 

Tighten bolt and nut on opposite side.

Worn rotor or stator

Replace worn parts

Oil level

Oil drain

Breather cap

Lubrication

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).
