(c) Housekeeping problems due to water runoff, spillage
and scraper droppings, common to belt conveyors,
are avoided.
(d) The trough can, if necessary, be enclosed to seal
against pressure differentials. Although this is not a
common requirement, several installations of John
Zink rotary kilns are equipped with Triple/S Dynamics
air-sealed dry ash dischargers.
(e) The steel trough can handle dry ash, or grate
siftings, at elevated temperatures that would damage
a rubber belt, or drag conveyor, as it can be surfacecooled
and exposes no moving parts, other than the
vibrating pan surface, to contact with the hot and
abrasive material.
