Practically all ball mills have a trunnion lifting hydraulic system which includes an hydraulic lift pump of any suitable type with a line connected to' the bottom of the bearing. Prior to starting, the pump is actuated to force lubricant between the trunnions and bearings, thereby lifting the entire mill off of the bearings.

One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure.

Proper mill trunnion seals help maintain bearing integrity and extend life. Mill trunnion seals must be designed to withstand operating conditions and effectively keep out dust, moisture and other contaminants that can affect mill trunnion bearing performance. 6. Proper lubrication is vital for trunnion longevity and performance.

The ball mill trunnion is located at both ends of the ball mill cylinder and plays the role of supporting and connecting the mill cylinder. Two ball mill trunnions are installed at both ends of a ball mill, one is the feed trunnion, which is the passage for the material to be transported into the cylinder, and the other is the discharge trunnion, through which the ground material is sent out.

The Hardinge Ball Mill consists of three sections. After the usual type of trunnion bearing the mill consists of a short conical section showing a sharp drop from feed entrance to maximum mill radius. A cylindrical section of varying length then follows and toward the discharge end connects with a comparatively long and conical section sloping ...

Once the mill is turning the bearing is selflubricated by OIL RINGS. They should be checked periodically. If you look closely at them you will notice that they have holes in them. As the rings revolve with the bearing these holes pick up oil from the SUMP in the bearing base and carries it to the top of the bearing.

With the design criteria established the following repair/reinforcement procedures were performed. Initially the mill was jackedup to remove the weight of the mill and the charge from the trunnion. The sections in the upper half of the trunnion that either exhibited cracking or were less than (.75″) thick were removed.

Depending upon available handling facilities, the head or shell can be lined separately ina repair bay, or alter assembly of the mill proper in the trunnion bearings. In the case of ball mills, all internal wearing parts will pass through the manhole, whereas in the case of open end rod mills they sill pass through the discharge trunnion opening.

Mistake 2 Over and under Lubrication. The second mistake we must avoid is adding too much, or not enough grease. Too much grease builds pressure, pushing the rolling elements through the fluid film and against the outer race. The bearing now has to work much harder to push the rolling elements through a mud bog of grease.

STEP 7. Bearing execution. STEP 8. Sealing, mounting and dismounting. Rolling bearings must be adequately lubricated to operate reliably. The lubricant is required to reduce friction, inhibit wear, protect the bearing surfaces against corrosion and may also be needed to provide cooling. This section describes: how to select between grease or oil.
