The Noble 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.

The 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 material’s 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 Feeder’s 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 feeder’s 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 pan’s 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.
