Different types of cracks in rotary drum dryer

Apr 01, 2016 Rotary drum dryers are the workhorses of the industrial drying industry, but even workhorses can have maintenance problems. Fortunately, most drum maintenance problems center around a few core issues involving specific equipment: Trunnion wheels and shafts. Trunnion bearings. Drum tires. Drum shell and head plates. Seals. Performing daily inspections goes a long way to
