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. Misalignment also occurs naturally, as a drum experiences normal wear and tear, causing the drum to gradually fall out of perfect alignment.
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. This will result in precise rotary drum alignment, with full-face contact of the tire on the trunnion rollers and an even load distribution between the trunnion rollers.
When the tire and trunnion surfaces show severe wear, action should be taken to correct the problem. Lack of maintenance could result in serious damage and downtime to your rotary drum. The damage could go beyond just the tire and trunnion and result in very expensive problems with bearings, piers, thrust rollers, and the gear and pinion.
Incorrect alignment created issues with the tires and trunnions magnifying thrust and alignment issues in the vessel. RSC precision ground both tires and all four trunnions. After performing a Two-Phase Alignment of the vessel, the equipment is back to normal and tracking between the 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.

TRUNNION. The steel rollers that support the drum by way of the tires. Over the years there have been trunnions made of steel, cast, rubber, and who knows what else. This paper will reference only steel trunnions, which are by far the most popular. Drums used in the asphalt industry generally have four trunnion rollers.
FEECO offers a state-of-the-art laser alignment service for drum shaft alignment, as well as other alignment needs. Why Proper Shaft Alignment is Important Whether you are running a rotary dryer, cooler, agglomerator, kiln, or other rotary equipment, proper alignment is key to extending equipment life and maintaining operational efficiency.

Rotary drum alignment is a primary contributor to overall drum performance and longevity. Much like tires and trunnion wheels, the alignment of a drum affects several components, and when allowed to run out of alignment, can result in a wide range of problems.
Tires, or riding rings, and trunnion wheels (rollers) are the support base on which a rotary drum is mounted. As the primary point of contact and rotational movement, wear on tires or trunnions is an early indicator of an underlying issue, making identifying wear a critical aspect of maintaining a rotary drum, whether it be a dryer, cooler, kiln, or granulator.

Intro. Rotary drum dryers are the workhorse of the industrial drying industry. But even workhorses can have maintenance problems. However, they tend to boil down to a few core issues involving the following equipment: 1) trunnion wheels shafts, 2) trunnion bearings, 3) drum tires, 4) drum shell and head plates, and 5) seals.

Rotary Dryer Trunnion Adjustment Once the engineer has determined where and how much adjustment is needed, there are two options for adjustment to achieve proper alignment shimming and skewing. Shimming involves adding shims, or metal plates, under trunnion bearings in order to adjust the elevation of the trunnions.
