Drum Shell
The drum shell (or pulley face) can be produced in aluminium, steel or stainless steel and is normally crowned to facilitate central belt tracking. However, cylindrical shells can be produced and fitted with external sprockets or rotary brushes for special applications. Rubber NBR, PU and other coatings can be applied to the shell to increase friction between the shell and conveyor belt and hot vulcanised or moulded profiled lagging can also be applied to drive plastic or steel modular belts.

Famous quotes containing the words drum and/or shell:
“Only the drum is confident, it thinks the world has not changed;”
—Robinson Jeffers (1887–1962)
“How then can we account for the persistence of the myth that inside the empty nest lives a shattered and depressed shell of a woman—a woman in constant pain because her children no longer live under her roof? Is it possible that a notion so pervasive is, in fact, just a myth?”
—Lillian Breslow Rubin (20th century)
