Single-Flow Feeder is built to withstand raw pit material that has not been crushed or
processed, making it ideal for use as a primary feeder and in other applications that
require the handling of large lump sizes.
feed rate of the Noble Single-Flow Feeder is accurately controlled either locally or
remotely. Feed rates are determined by the distance the pan moves, not the speed of
movement. The material enters through the feed "throat" and flows into a
horizontal feed pan that extends beyond the materials natural angle of repose
(approximately 37°) to prevent free flowing. The feed pan moves at a constant rate of 450
cycles per minute to prevent material buildup and clogging. The pan oscillates up to
1/2" in each direction, parallel to the conveyor, causing material beneath to be
displaced and discharged.
The Single-Flow Feeders discharge opening is twice as
large as the Noble Dual-Flow Feeder, therefore more headroom is necessary. As material is
discharged, it is replaced by an equal amount of material over the feed throat entry,
resulting in positive displacement feeding. The feeder discharge is so close to the
conveyor, large rocks drop only a short distance and belt damage is prevented. Since the
tail section of the conveyor only needs to extend slightly past the feeders
discharge point, the Noble Single-Flow Feeder also is ideal for use at the tail end of
reclaim tunnel conveyors.
The Noble Single-Flow Feeder requires minimal maintenance and
is easy to install. The feed pan liners are abrasion-resistant, preventing caking and
buildup of sticky material. The liners are also sectional -- 2-3 sections on each side and
3-4 on the bottom -- so only worn sections are easily replaced by operating personnel. The
pans slight lifting action at the discharge point also prevents shearing and
excessive liner wear.
The Noble Single-Flow Feeder is shipped completely assembled.
The feed "throat" entry is flanged for bolting to the bottom of bins or reclaim
tunnel feed entry chutes. An optional companion flange is available or customer-provided
flanges can be approved for easy installation before the feeder arrives.
