Roller Bearing Lubrication Failures Solved. A global chemical manufacturing company is operating a plant with a large rotary kiln. The kiln is part of a single-stream process, so any downtime at the kiln plant has immediate and severe effects on several downstream manufacturing units. The resulting lost production has serious cash loss ...
The above photo shows the location of the ACU-230 sensor installed on a lime kiln carrying roller fric - tion bearing. The sensor features a separate sensor head and electronics in separate aluminium enclo - sure, ideal for applications with high temperature at the monitoring area. Poor lubrication
Kilns are installed at an incline, and as a result are subjected to a downward or thrust movement. This movement must be limited and is controlled by a thrust roller. Though applied separately, the thrust roller uses the same lubricants as the trunnion wheel roller and support bearings. The thrust roller bearing requires either grease or oil:

Typically lime kilns are supported by journal bearings, but Sunila's lime kiln 2 has cylindrical roller bearings. These were originally grease-lubricated, but this was soon changed to a circulating oil lubrication system at the burning end bearings because of high ambient temperature. Experience has shown that the life of these bearings is ...
lime bricks. THE PFR KILN. FOR SOFT-BURNT LIME, THE HIGH- REACTIVE QUICKLIME. The PFR kiln from Maerz is ideal for the production of soft-burnt lime. The lime is calcined in a parallel flow. The feedstock and the combustion gases move in the same direction from top to bottom. The energy needed for the calcination is supplied at the begin-
mechanism (either a bearing end cap or a thrust collar) becomes high and increased bearing temperature results. The reaction to the axial motion of the support roller is kiln movement in the opposite direction. This axial movement of the kiln is resisted by a thrust roller, which may become overloaded and either fail or overheat.
Rotary kiln Support roller adjustments A) Bearing roller B) Kiln C) Carrying roller Index finger indicates bearing (A) and direction to move. Kiln (B) moves in direction indicated by thumb of the same hand. Alternatively stand on the up running side of the kiln. Now with palms facing up an inward movement on the right bearing will move the kiln
Trunnion rollers are a critical part of a rotary kiln, responsible for supporting the massive weight of the kiln itself and keeping it rotating smoothly. These rollers are under incredible stress at all times, whether the kiln is in use or not, and must be maintained in good condition for the kiln to run properly.
Pulp mill lime kiln trunnion bearings Pulp and paper producer Ontario, Canada Situation An Ontario-based pulp and paper producer operates a pulp mill lime kiln, which operates at temperatures as high as 1,652°F (900°C) and is supported by trunnion bearings. Lubricated with a conventional mineral-based circulating oil, the trunnion bearings ...
Own to the rotary kiln such as cement kiln, lime rotary kiln and shaft kiln is widely used in building materials, chemical industry, nonferrous metallurgy industry, black metallurgy, and refractory materials.Rotary kiln's support roller is an important module, and it has the character of large bearing load, poor working environment, constant running, and complex maintenance.
Whether your bearings need maintenance, replacement parts or full unit replacement, we have the tools, expertise and knowledge to keep your process and equipment at …
The wheels are mounted to steel support bases with sealed roller bearings. Support rollers bear the weight of the drum. 3D model of a rotary kiln trunnion base. Click image to view larger. Conclusion. The bearing and drive components on a rotary kiln serve as the base of the unit, providing support and rotational movement to the drum.
The supporting roller bears the whole rotary kiln part weight (main part barrel, lining brick, heat exchange device in stove, material, tyre, girth gear ring) The barrel and kiln tyre can smooth rotate on the supporting roller So bearing performance of support roller has become one of the measure standard of the rotary kiln product high quality
With a kiln's outer shell reaching 400 °C, that's enough to reduce lubricant viscosity inside bearings and eventually cause failure. What's more, tumbling loads, dust and outdoor conditions can lead to shaft misalignment, bearing contamination and additional failures. SKF bearing and lubrication solutions are proven to withstand these ...
ROTARY LIME KILNS Slides 1 and 2 are the title and outline for the presentation. Slide 3, below, shows a schematic of the exterior of a modern rotary lime-reburning kiln. Slide 4 shows a schematic of the interior features of a lime-reburning kiln. Rotary lime kilns are large steel tubes that are lined on the inside with refractory bricks.
Challenge. The bearings in the kiln cars failed because the "high temperature" commercial grease being used broke down and hardened in the bearings under the high-temperature conditions. The kiln reaches temperatures over 2,000°F (1,093°C), while the area under the kiln car – where the bearings are located – reaches up to 500°F (260°C).
