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.

Then bloody swords and armor should not be;
No drum nor trumpet peaceful sleeps should move,
Unless alarm came from the camp of love.”
