FeedingFeeders are necessary whenever it is desired to
deliver a uniform stream of dry or moist ore, since
such ore will not flow evenly from a storage reservoir
of any kind through a gate, except when regulated
by some type of mechanism.
Feeding is essentially a conveying operation
in which the distance travelled is short and in
which close regulation of the rate of passage is
required. Where succeeding operations are at the
same rate, it is unnecessary to interpose feeders.
Where, however, principal operations are interrupted
by a storage step, it is necessary to provide
a feeder.
A typical feeder consists of a small bin, which
may be an integral part of a large bin, with a gate
and a suitable conveyor. Feeders of many types
have been designed, notably apron, belt, chain,
roller, rotary, revolving disc, and vibrating feeders.
In the primary crushing stage, the ore is normally
crushed as soon as possible after its arrival at the
surface. Skips, lorries, trucks, and other handling
vehicles are intermittent in arrival whereas the
crushing section, once started, calls for steady
feed. Surge bins provide a convenient holding
arrangement able to receive all the intermittent
