Dual Flow Feeder

Dual Flow Feeder

The feed rate of the Noble Dual-Flow Feeder is accurately controlled either locally or remotely. Feed rates are determined by the speed of the pan’s movement, not by the distance the pan moves. 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 rate of 450 cycles per minute to prevent material buildup and clogging. The pan oscillates 1/2″ in each direction, parallel to the conveyor, causing material beneath to be displaced and discharged.

The Noble Dual-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 – 1-4 sections on each side and 2-4 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 Dual-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.

The Noble Dual-Flow Feeder discharges material in two equal streams, taking advantage of the material’s natural flow. This patented design gives the Noble Dual-Flow Feeder a very low profile and a dramatically-reduced size and weight, making it ideal for use in reclaim tunnels and other applications where space is limited. The Noble Dual-Flow Feeder also can operate on less than half the horsepower of conventional single discharge feeders with the same capacity.
