Anion WS 5300 Kiln Trunnion and Mill Bearing Fluid. Along with superior hightemperature performance, it makes the kiln operation more economical by minimizing wear and reducing maintenance. ANION WS5300 performs well under most operation conditions and excels when roller shaft temperatures rage from 150 to 200C.
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
May 25, 2023 8:55 am News The ball mill trunnion plays a crucial role in the efficient operation of cement mills, autogenous mills, and coal mills. As a key component, the mill trunnion provides support to the mill shell and ensures proper alignment, allowing the mill to function effectively.
Ball Mill TRUNNION BEARINGS. Swivel type leadbronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion.

A lowest efficiency of 93% corresponded to trunnion bearing temperature, pinion bearing temperature, mill motor temperature, mill motor vibration, pinion gear vibration of ⁰C, 44 ⁰C, 59 ⁰C, mm/s2 and mm/s2, respectively. Decrease in any of the influential factors considered improved ball mill efficiency accordingly.

Ball mill inspection 2 Inspection during operation Key benefits FLSmidth uses its many years of experience and the knowledge gained Bearing lubrication system Trunnion Root cause analysis from installing almost 4000 ball mills Mill shell around the world to carry out essential Mill head bolts Performed during both normal ball mill inspections.
Oil lubrication failure on grinding mill trunnion bearings causes thermal stresses in surfaces and cracks at low stress region. • A contact temperature of 150 °C may causes a stress over the yield strength of the trunnion nodular cast iron.. The use of standard BS 7910 on fatigue crack propagation in the trunnion proved to be more accurate compared to ASME Section XI.
Heads Shells Gears and pinions Main bearings Trunnions Trunnion liners And more! Grinding mill head Material: cast ductile iron or cast steel Design standard: Metso FEA Segments: one, two, three, or four Type: feed/discharge, fixed/floating, integral with the trunnion Grinding mill shell Material: fabricated steel (welded)
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.
Increase in cement mill trunnion bearing temperature. May 12, 2013· re Increase in cement mill trunnion bearing temperature. Cement mill trunion bearing temperature may increaase due to following reasions: 1. HP pump pressure is low. 2. Cutoff time of HP pump after mill start up. 3. Mixing of contamination with oil. 4.
Set points: Slide Shoe Temperature: 75°C Alarm 80° C Mill stop 7 Holcim Group Support Ball Mill Bearings and Lubrication /TST Alarm Settings Trunnion bearings •70°C Alarm, 75°C Mill stop Trunnion bearings without temperature device, have to be checked by Pyrometer directly on the trunnion shaft surface during mill operation
Experience has shown that each bearing stabilizes to its own temperature, ranging between 90°F (32°C) and 125°F (52°C). Many factors, such as ambient temperature, quantity of oil, viscosity, bearing clearance, alignment, etc., contribute to the final operating temperature.
