Vibration Sag Mill Motor NDE Bearing | AMP Maintenance Forums
Is the mill vibration a lot higher than the motor vibration? No, Taking vibration at the pinion trunnion bearing all around 1.5mm/sec rms,, quite smooth What does the spectrum on the concrete look like? (Does it resemble the motor beairngs or the mill or [longshot] maybe even something else).I will get them to send a spectrum of the concrete ...
A trunnion (from Old French "trognon", trunk) is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. Alternatively, a trunnion is a shaft that positions and supports a tilting plate. This is a misnomer, as in reality it is a cradle for the true trunnion.
"These trunnion bearings are selected based on the grinding mill size and type, in addition to the site conditions and output required of the mill," NTN-CBC Australia product manager Fabio Rebecchi says. "In these instances, we're seeing a trend for extra-large spherical roller bearings, which are critical in ball mill application.
Semi-autogenous grinding (SAG) mill liner design ... - The AusIMM. generate both thrown and cascading ball-milling actions with shell linings ..... pulp out of the mill through the trunnion opening (see Figs. 1 and 9).
Trunnion-supported mills A relatively small, stiff bearing journal provides an optimal surface on which to operate an oil-film bearing. This support option can accommodate mill body splitting, making it the preferred option for large mill sizes.
Aug 18, 2015 · Trunnion Bearings of Ball Mill These casting surfaces such as the neck contacted with the mill spherical tile and the circular arc neck contacted with cylinder are free of blowhole and sand inclusion in the cast process; the position parts contacted with spherical tile need to grinding after machining in machining process.

Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of any grinding mill. They must carry the load of the shell assembly ...
Sep 03, 2014 · The Ernest Henry SAG mill has this design and although it has suffered contamination of the bearing oil by mill slurry, it has operated continuously since 1997 without a structural failure. The sealing of this region has been improved by a number of pressure grooves and barriers being added to the joint in newer mills.
