Proper lubrication is crucial for trunnion bearings, so ensure they are adequately greased. Grinding Media: Inspect the condition of the grinding media, such as steel balls, used in the mill.
Ultraplex 2 Moly Plus Grease for raise boring roller bearings under high torque and temperature. Protect your roller bearings against vibrations and impacts with Ultraplex Moly Plus, a calcium sulfonate grease with a high percentage of solid lubricants.
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.

The bearings in smaller mills may be grease lubricated, but oil lubrication is favored in large mills, via motordriven oil pumps. The effectiveness of normal lubrication protection is reduced when the mill is shut down for any length of time, and many mills are fitted with manually operated hydraulic starting lubricators, which force oil between the trunnion and trunnion bearing, preventing ...

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 ...
After cleaning the various parts, the gear and pinion teeth, trunnion journals and bearings, shafting and such, should be protected against rusting or pitting as well as against damage from falling objects or weld splatter. All burrs should be carefully removed by filing or honing.

Lubrication of the trunnion bearing is essential to reduce wear on the moving parts. Meeting the customer's specifications, AFS manufactured two vertically mountable hilift trunnion bearing lubrication skids. The unit is rated to operate at 6000 psi/413 bar thus pressurizing the bearing housing, lifting the trunnion and creating a minute ...
On a 11'6" x 22'0" Ball Mill, the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings, and high pressure oil for hydrostatic lift of the feed and discharge trunnions during startup of the mill.
From mill shells to trunnion liners and everything in between, a trunnionsupported mill works better with more durable, higher performing parts. Our replacements provide premium service to customers, promoting innovative design and increased durability. Enjoy lower costs and less downtime with EXCEL premium trunnionsupported mill parts.
Ball mill trunnion replacement Drawing on years of experience and process knowledge, our trunnion replacement service combines our stateoftheart trunnion design, highquality parts and expert onsite installation teams to ensure reliable mill operation. Suitable for both FL and nonFL mills
This is a brief video of key processes and pipe works in lubricating a trunnion bearing. It doesn't highlight all the parts or tools or the kind of lubricant...
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.
Outotec solution: trunnion bearing lubrication system retrofit featuring: Customsized reservoir Filtration system and heat exchanger Temperature, flow, and pressure instrumentation Reservoir to separate contaminants from lubricant Sized for proper retention time, allowing dirt and air to separate from the oil
Ball Mill Trunnion Bearing also known as the ball mill trunnion, is an important part of the ball mill that carries the rotation of the cylinder of the ball mill. ... After the ball mill bearing is installed, a lubrication test and load test should be carried out to ensure that the bearing can work normally. Maintenance.
plain bearing are the bearing liner and the shaft. The shaft is composed of highquality, wearresistant, structurally strong steel.

I only worked with SAG mills where the high pressure lubrication system is used at startup of the mill. But once was I worked with a Fuller 18x9 mill we had a heating problem in the bearing that was due to a deformity of the trunnion.
trunnion was more critical. This phenomenon is common on mill bearings lubrication failures. The fixed trunnion which is always the trunnion at the side of the drive train is the trunnion which has no gap between it and the bearing bushing. The clearance is all Fig. 13. Temperature gradient distribution. Fig. 14. Stress gradient distribution ...

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.
Trunnion bearings in cement and grinding mills are exposed to extremes in heat, cold, rain and harsh airborne particulates. To help protect bearings against these extreme conditions and avoid possible production headaches, large amounts of grease are used to purge contaminants from trunnion housings.

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.
