Trunnion Roller Resurfacing Wear on the surfaces of the kiln tires and support rollers makes it difficult, if not impossible, to make support roller adjustments to achieve a proper alignment. An ideal hot kiln alignment involves not only the horizontal and vertical axis of the shell, but the balance of the axial thrust of the kiln as well.
The mechanics did not realize that the rolling element of the trunnion that was removed had a taper on it. Thus, the new trunnion went in on an angle that created a tremendous thrust load, besides the misalignment. Bearing manufacturers indicate that spherical roller bearings are not that good in high thrust load conditions.
Carrying and Thrust Roller Alignment. When rollers are set parallel to the centerline of the kiln, the roller shafts should bear against the downhill bearing caps. This can be checked by tapping the bearing caps with a hammer. The loaded caps will emit a solid sound.
C. M. CONSULTING. A Division of Cliff Mansfield Incorporated Laser Trunnion Adjustment by Cliff Mansfield Many asphalt plants suffer from trunnion and tire problems relating to misalignment and poor adjustment procedures. In past articles I have talked about various methods of repairs such as trunnion/tire grinding.
The alignment system provides real-time axial force data and precise identification of each roller's neutral position and allows for precise shimming to correct mismatched tyre or roller slopes. PKSE offers the Thrust Monitor Alignment system as an in-situ service carried out by PKSE engineers or it can be purchased as a permanent ...

This will move the drum away from the feed side thrust roller and toward the discharge end. B TRUNNION ALIGNMENT The following is a list of indications that the trunnion rollers are not properly aligned.-"Pinging" of trunnion rollers with blue spots appearing on the surface of the tire.-Uneven wear on the drum tires or trunnion rollers.
With this information, we can determine where to place each trunnion roller so the drum will be centered over the bases. In addition, we can determine the amount of shim required at each bearing location to assure that the trunnion rollers and drum will all have the same slope.

Though aligning a drum is a simple solution, leaving a drum out of alignment can result in, such as trunnion wheels, tires, drive components, and thrust rollers, Misalignment causes a drum to ride harder against the thrust roller, therefore.
Thrust Idler – Thrust Roller. Rotary Service Company, (RSC), provides thrust idler for all trunnion mounted rotary equipment. The Rotary Service Company retrofits your rotary equipment with thrust idlers, quickly in the field, no matter who the manufacturer.
Stress on a kiln is caused primarily by improper alignment of tire pad clearances and the support rollers. Kiln operation should employ a well-developed preventative maintenance plan, which includes items such as replacing support pads and trunnion roller base replacement.
Rotary Kiln & Dryer will modify or repair existing rotary equipment of any make either on an onsite or offsite basis. Learn more... Used Inventory. Vast inventory of used equipment. Search our online used equipment inventory. We have a large selection of trunnion rollers, thrust rollers, gears, tires and much more at a fraction of the cost of new.
· Thrust roller damage · Trunnion & tire wear ... Whether your equipment is driven by gear, chain, belts, friction, or a combination of such, alignment of these components is critical to performance and longevity of the equipment. Evans and Daniels specializes in drive analysis and alignment correction.
Apr 09, 2010· Computerized support roller alignment for rotary dryers, rotary kilns, rotary granulators, asphalt drums, rotary coolers, rotary conditioners that use spherical roller bearings on the support rollers.
maintenance is the stable alignment of the support rollers. Roller positions must be consistent with minimum ovalities, low support roller thrust loads, and a straight kiln axis. The preferred procedure to assure those conditions is a hot kiln alignment, where all alignment measurements are taken when the kiln is under normal operating conditions.

SKF bearing units typically consist of a housing, bearing, seal, lubricant and shaft locking mechanism. The units are preassembled and adjusted at the factory. These ready-to-mount units are available with either ball or roller bearings.
The change in the alignment can be seen in the upper left picture. The yellow bars approximate the distance between the edge of the raceway and the edge of the roller at the initial installation of the trunnion assembly. There is a very slight angularity set on it due to setting a slight thrust on the trunnion assembly itself.
Roller Adjustment and Skew Page 3 A "full thrust kiln" is simply one fitted with static thrust rollers that are large enough to fully support the kiln with the carrying rollers neutral. Sometimes with larger and longer kilns there are thrust roller assemblies on two or even more piers.

K series Bearing types • Spherical roller bearings Bearing dimension series • 39, 48 and 49 Shaft diameter range • 825 to 1 460 mm Typical bearing-shaft combinations ... machined to make alignment easier and to provide a flat surface for stops († fig. 3).
The thrust rollers are mounted with about ¼" of tolerance from the tire. The drum should ride evenly between the thrust rollers, not pushing harder on one than the other. Drum training is done by skewing the trunnion bearings until proper float is achieved. Advantages to a FEECO Kiln Alignment
axial thrust of the kiln with normal roller adjustments. The Base Line Alignment will retard wear issues and allow for ease in controlling the kiln axial thrust. 3. By balancing the alignment of the kiln/dryer, the axial thrust of the kiln/dryer and by moderating thrust conditions on all bearings, the kiln/dryer will operate a maximum efficiency.

The T-Trac™ Alignment can save your operations tens of thousands of dollars in premature trunnion and tire wear. Helps avoid emergency shutdowns for trunnion and thrust roller interference.
Proper drum base installation will help to ensure that the drum properly 'floats' between thrust rollers. Misalignment in a base will propagate through the drum, causing wear and damage to other drum components, such as trunnion wheels, tires, drive components, and thrust rollers.

drive, bearings & trunnions The drum drive system is the single most problematic source of many rotary drum dryer systems. It's difficult to get 50 tons of steel to rotate in perfect alignment on four trunnion wheels held up by concrete and structural steel.
Because most alignment issues relate directly to the condition of tires and trunnions on the vessel, floating the vessel is impossible without tire and trunnion surfaces being flat. Visit our Tire and Trunnion Grinding page for more information on obtaining a quote for your vessel.
