An apron feeder is a reliable feeding method for when the material to be conveyed is lumpy, abrasive, heavy, high temperature, or where a feeding solution more robust than a traditional belt feeder is required. Apron feeders are designed to feed material at a desired volumetric rate to downstream equipment and convey material on a series of overlapping pans attached to multiple strands of a heavy tractor crawler-type chain.
Apron feeders are typically located under rail or truck receiving hoppers, storage bins, or stockpiles and withdraw the material to be discharged to belt conveyors, crushers, or other process equipment and can handle conveying inclinations of up to 28 degrees.
TAKRAF apron feeders are particularly suitable for severe or extreme applications and are designed to cater to specific requirements determined by the material, capacity and geometry. If required, variable speeds can also be achieved through the use of an optional Variable Frequency Drive (VFD) or hydraulic drive.
Robust and reliable for extended service life
Our feeders combine heavy-duty frames with standard chains and rugged pans (cast manganese steel or formed carbon steel) to provide an extended service life. Impact rails below the pans also minimize deflection and absorb the forces of falling material. Our diverse product range covers standardized apron feeders, as well as specific heavy-duty feeders with large handling capacities exceeding 10,000 t/h. Depending on site and/or client specific requirements, we are able to preassemble machines in our fabrication facilities and ship in large pieces to site.
Inboard vs. outboard design
TAKRAF’s apron feeders are available with either an inboard or an outboard design. An outboard design implies that the chains are mounted outside of the skirt board area, hereby protecting both the chains and rollers from spillage material. An inboard design however offers its own unique advantages in boasting far shorter and lighter pans.

Customer Project Name Apron feeder for mobile crushing plant Rio Tinto Coal Australia Clermont coal mine 2009
Apron feeder for Clermont coal mine
TAKRAF delivered the apron feeder as part of the fully mobile crawler-mounted crushing plant BRF-W2-10000 for the Clermont coal mine in Australia. The apron feeder receives the material by shovel and feeds the crusher of the mobile plant.

Belt Conveyors - for mining applicationsBelt conveyor systems continuously transport all forms of material, including excavated and crushed rock, in an efficient manner due to their 100% effective availability. They cover a wide range of applications, from mining or extraction to in-plant or overland where they convey material over long distances, passing through curves and rough relief areas.
Belt FeedersBelt feeders are short belt conveyors that are specifically designed for material flow regulation, extracting material from one area and ensuring that downstream equipment receives the appropriate volume
Mobile Conveyor BridgesMobile Conveyor Bridges (MCBs) operate as flexible links between mining machines and bench conveyors and increase the operating range of the system.
Mobile Transfer ConveyorsMobile Transfer Conveyors (MTCs) are "multi use" equipment that are used to both increase performance and flexibility of many mining operations. Mobile transfer conveyors work as a flexible connection between a mining machine and bench conveyors. Moreover, mobile transfer conveyors are easily relocatable and positionable, improving performance, flexibility and efficiency.
