As the industry’s leading rotary drum manufacturer, FEECO rotary drum shells have the well-earned reputation for the highest quality available.
REPLACEMENT SHELLS FOR ROTARY DRYERS, COOLERS, & KILNS
FEECO manufactures custom replacement drum shells for rotary dryers, coolers, kilns, and other types of rotary equipment.
We know that proper shell manufacturing techniques are integral to rotary drum service life and performance, so we engineer and fabricate all of our drum shells to exacting specifications against tight tolerances and stringent quality standards. All drum shells are manufactured to run true and concentric.
When working with thermal applications, FEECO drum shells are engineered to eliminate distortion and misalignment resulting from high operating temperatures.
Numerous aspects of the replacement shell can be customized to suit the precise needs of the application. This includes shell thickness, materials of construction, and the provision of internals.
SHELL THICKNESS
FEECO can accommodate varying shell designs and thicknesses to meet your processing needs and maximize equipment service life.
MATERIALS OF CONSTRUCTION
Various materials of construction are available, including:
- Stainless steel (polished or unpolished)
- Specialty alloys (hastelloy, inconel, etc.)
- Carbon steel
- Cladded steel
- AR steel
- Explosion bonded
Shells can also be fitted with insulation for reducing heat losses.
INTERNALS
FEECO can supply shells with the necessary internals. Depending on the application, this might include custom flights (material lifters), tumbling flights, or other modifications designed to maximize heat transfer efficiency and optimize performance.
ADDITIONAL ROTARY DRUM COMPONENTS
In addition to providing replacement shells, FEECO can offer a range of support components, including tires and trunnions, girth & sprocket gears, combustion chambers, liners, seals, refractory, and more.
INDICATIONS THAT A SHELL MAY NEED REPLACEMENT
Damage to the drum shell comes in many forms, some more obvious than others. Obvious signs include cracks or holes in the shell, welds, inlet/discharge plate, or other components. The shell may also be visibly out of round, flexing, or not running smoothly throughout rotation. This may be exhibited by a chattering or vibrational noise.
Thin spots in the shell or internal failures from acid attack, abrasion, or fugitive material may be less obvious. In addition to visual inspection, these types of problems can be indicated by thermal imaging equipment, or by measuring temperature around the drum’s circumference and length. FEECO can also assess this by measuring and profiling drum shell thickness.
