Problem:<br />
Bearing ring inside dimension, <strong>and</strong> imperfect dryer shell outside dimension of a 15 ft. diameter by 80 ft.<br />
long horizontal rotary bark dryer created voids between the mating surfaces. The void spots would<br />
cause uneven stress loading <strong>and</strong> subsequent fatigue cracking.<br />
Solution:<br />
A 3/16” pocket was machined on the shell side of each positioning wedge. The bearing ring was<br />
positioned over the shell. Brushable Ceramic was mixed <strong>and</strong> heated to 110º F. It was quickly<br />
transferred into caulking guns. Brushable Ceramic was injected between the bearing ring <strong>and</strong> dryer<br />
shell. Inspection or bleed holes indicated even dispersion of Brushable Ceramic. Brushable Ceramic<br />
provided a more uniform load distribution ultimately extending shell service life.
