e RULA BULK MATERIALS HANDLING

Reclaim Feeder

Reclaim feeders are primarily used for efficiently extracting and feeding materials from stockpiles, bins, or hoppers in industries such as mining, aggregate, power generation, and material processing. These low-profile, heavy-duty machines are designed to handle a wide range of bulk materials – from coal and iron ore to aggregates and biomass – by reclaiming material from storage and feeding it directly onto conveyors or into processing equipment. Typically equipped with a belt or chain conveyor system, reclaim feeders can deliver a controlled, consistent feed rate, crucial for maintaining steady production flow. Their rugged construction and ability to operate under various environmental conditions make reclaim feeders ideal for both stationary and mobile applications, helping improve efficiency and reducing manual handling requirements in high-throughput operations.

Belt-over-Apron Type

This type of reclaim feeder has a belt-over-apron design with steel aprons installed on the chain under the conveyor belt. This provides impact resistance to the bulk material being dumped directly onto the belt. The belt prevents spillages when conveying fine material ore. This type of feeder is designed specifically for abrasive and fine materials and has the spillage control benefits of a conventional conveyor system, with the added benefit of the robust steel aprons to handle high loads and impact.

The feeder is chain and sprocket driven, with the chain protected from the bulk material with skirt plates and rubber seals.

The feed (tail) section is designed with a slight inclination to allow water to drain away from the machine if the bulk material being fed has a high moisture content. The discharge (head) section is designed with an incline to minimize machine length, while still preventing material from running back on the conveyor. The feeder has an adjustable discharge chute onto the receiving conveyor, which can be at a range of orientations from parallel through to perpendicular.

Belt cleaners clean the return side of the conveyor belt and prevent material build-up at the tail sprocket. A manual screw take-up ensures both chain strands are equally tensioned.

Bumper beams fitted with low friction liners are installed beneath the steel aprons to prevent excessive apron pan deflection at the high impact areas. Conventional skirt rubbers are used to prevent the bulk material from reaching the chain running surfaces to prolong the chain life.

The reclaim feeder has a modular retaining wall design, with options to extend the wall as required. An adjustable profile plate controls material throughput (additional to speed control via Variable Speed Drives). If the machine is required without a VSD drive, the profile plate will be the main flow control device.

Advantages
  • Can accommodate fines
  • No adjustment needed on belt tracking.
  • Heavy duty design with steel aprons to withstand loading forces with trapezoidal shape design to minimize the apron height and reduce sprocket size.
  • Feeder spillage minimized with belt-over-apron design.
  • Tail section at an incline to allow excess water to be removed.
  • Belt with "raised edge" prevents material from reaching chain roller running surface.
  • Low feeding height, eliminating the need for ramps for Front End Loaders.
  • Material can be fed from either side of the machine.
Chain-Scraper Type

This type of reclaim feeder is similar to the belt-over-apron type, in that sprocket-driven chains initiate the conveying. However, instead of using a belt and apron elements to convey, scraper flights move the material over a stationary, wear-protected deck. Unlike the belt-over-apron type, the chain is exposed to the bulk material. This type of feeder is suitable for coarse products.

Similar to the belt-over-apron type, chain scraper feeders can be used with modular retaining walls.

Advantages
  • Ideal for coarse products.
  • No adjustment needed on belt tracking.
  • Heavy duty design with reinforced and wear-protected deck.
  • Low feeding height, eliminating the need for ramps for Front End Loaders.
