A high-capacity conveyor that takes peaks of production from another conveyor
and retains and/or discharges the material when production drops. Such a
conveyor may be laid under or alongside a trunk belt near its discharge end.
The floor of the bunker comprises a slow-moving steel plate conveyor operated
by hydraulic or other power. A movable plow plate, situated over the trunk
belt, diverts the material sideways into the bunker conveyor. See also:
