Mar 01, 2016#0183;#32;Oil lubrication failure on grinding mill trunnion bearings causes thermal stresses in surfaces and cracks at low stress region. A contact temperature of 150 #176;C may causes a stress over the yield strength of the trunnion nodular cast iron.
BEARINGS Identitging and correcting causes of bearing faihue. Precision ball bearings are designed to have a long and useful Iie. Assuming the application is correct to begin with, maximizing longevity means bearings must be properly installed, lubricated and maintained. Poor operating environments. oarticularlv moist or contaminated areas.

Improper lubrication. Improper lubrication is the major cause of bearing failure. Issues include: too much lubricant; too little lubricant; using the wrong lubricant; mixing incompatible lubricants; incorrect lubrication intervals; using old, deteriorated grease or oil; and water contamination.
The SAG mills use a minimal ball charge of 6 to 15% Sign, which is dependent on the support provided by the hydrostatic trunnion bearings SAG Mill .

The asset is a verticallymounted, belt driven grinding mill, as shown in Figure 1. The drive spindle has three (3) bearings: two (2) cylindrical roller bearings and one (1) ball bearing. The mill is being belt driven by a 100 hp, twopole motor. The mill normally operates at 3,150 rpm.
If a bearing overheats, the hot lubricant breaks down and can cause scoring and even etching of the bearing surfaces. Also, water and other corrosive elements can create this condition, which lead to spalling down the road. Burned or oxidized lubricant may leave a dark coating on bearing surfaces.
Causes: Inadequate bearing clearance, overheating, insufficient oil supply, excessive load, or operation with a noncylindrical journal
The mill rotor bearings, which are mounted in the steel housing, are two 2 cylindrical roller bearings, NU 316 ECMC3, and one 1 grooved ball bearing, SKF 6316 C3. The bearings have failed several times over a period of two 2 years. Before this time, the mill had no recorded bearing failures
What are the reasons and solution for liner breakage? Tell us about effect of changing liner geometry, adding some feature to liners, type of material and metallurgical operation of liners on deceasing may happen for both of them but since nowadays mostly rubber liners are used in ball mill
How to Identify Whether Bearing Ball Mill is Failure or Not Time: . Bearing is a main vulnerable part of ball mill. During the operation of ball mill, the bearing can appear some faults due to stress, assembly or other reasons. In order to reduce the impact on production, we need to judge timely whether the failure occurred ball bearings.

Jul 03, 2018#0183;#32;There are several reasons why bearings fail Here Are The Seven Most Common Reasons Why Bearings Fail: 1. Lubrication Failure. Lubrication should be one of the first points considered in troubleshooting a bearing failure. Because many options are available, lubricants are often misapplied.
Bearing damage can occur for many reasons. Problems such as misalignment, unbalance, looseness and friction are all telegraphed through the bearing, sometimes leading to failure. And since bearings are often the most important machinery components, failure can result in costly downtime, damage to adjacent parts and significant repair costs.
Wear caused by abrasive particles. Small, abrasive particles, such as grit or swarf that have entered the bearing by some means or other, cause wear of raceways, rolling elements and cage. The surfaces
are replaced prior to failure for security (preventive) reasons. Approximately 0,5% of bearings are replaced because they are damaged or fail. This means that some 50 000 000 bearings are replaced
Jul 31, 2013#0183;#32;The mill rotor bearings, which are mounted in a steel housing, are two (2) cylindrical roller bearings, NU 316 ECM/C3, and one (1) grooved ball bearing, SKF 6316 C3. The bearings have failed several times over a period of two (2) years. Before this time, the mill had no recorded bearing failures
1. Lubrication Failure. According to a recent study, up to 80 percent of bearing failures are caused by improper lubrication. This includes insufficient lubrication, use of improper lubricants or excessive temperatures that degrade the lubricant.
