Start with the current design range and documented RKF configurations to identify pans, liners, chains, chain pins and bushings, rollers, sprockets and tensioners, then confirm materials and drawing for a quotation.
PAF / RKF heavy-duty apron feeders are customized to project conditions. This page provides design ranges, official configuration examples, installation positions, material selection, drawing checks and an enquiry route to help confirm spares against the installed equipment records.
This product is customized to project feed conditions, capacity, installation space and downstream interfaces. The table lists only ranges explicitly stated in the current public FLS datasheet.
| Series | Pan width | Equipment length | Chain size | Maximum feed size | Maximum inclination | Maximum speed | Drive power |
|---|---|---|---|---|---|---|---|
| Primary Apron Feeder PAF / RKF | 1.0–3.0 m | Up to 30 m | D4–D10 | Up to 2,000 mm | Up to 26° | Up to 30 m/min | 45 kW–2 × 700 kW |
These two examples come from the official FLS product brochure and support identification of historical installations. They are not a complete list of current configurations.
| Configuration designation | Width | Length | Chain size | Chain arrangement | Document status |
|---|---|---|---|---|---|
| RKF 2.2 × 15.8 - D8 | 2.2 m | 15.8 m | D8 | Inboard chains | Project configuration example in the official FLS product brochure |
| RKF 3.4 × 17.0 - D9 | 3.4 m | 17.0 m | D9 | Outboard chains | Project configuration example in the official FLS product brochure |
The numbers on the diagram correspond one to one with the rows below.

| 2 | Chain | Continuous traction chain below the pans | FLS apron feeder (illustrated design) |
| 3 | Drive assembly | Side of the head end | FLS apron feeder (illustrated design) |
| 4 | Main frame | Below the pans and chain | FLS apron feeder (illustrated design) |
Start with pans directly exposed to ore impact and abrasion, then review receiving, sidewall, tail, head discharge and drip pan positions. Each item links to the relevant part and material pages.
Apron Pan / Feeder Pan
Pans receive large rocks and circulate with the chains, making them a principal impact and abrasion component. Check pan width, pitch, thickness, overlap direction, ribs, connecting holes, chain mounting distance and the head/tail wheel clearance envelope.

Impact Plate
Installed in high-drop receiving zones, these plates distribute direct impact from large lumps on pans, supports and frames. Check installation section, plate shape, thickness, hole pattern, fastening structure, material drop point and safe clearance to pans.

Side Liner / Skirt Liner
These liners protect the hopper or skirt sides and contain material flow. Check left/right side, segment order, plate thickness, hole pattern, overlaps, pan clearance, material bed height and leakage paths.
View Part Details →
Tail / Inlet Liner
These liners protect the tail inlet and hopper transition. Check feed direction, installation side, liner profile, plate thickness, hole pattern, overlaps with adjacent liners and clearance to returning pans.
View Part Details →
Head Discharge Chute Liner
These liners protect the head discharge area and changes of direction in downstream chutes. Check discharge trajectory, mounting face, segment layout, plate thickness, hole pattern, adjacent structural clearances and downstream equipment interfaces.
View Part Details →
Drip Pan Liner
These liners protect the collection pan below the return chain from accumulated fines, dragging and cleaning wear. Check segment length, width, plate thickness, hole pattern, cleaning direction and clearance to return components.
View Part Details →Parts with the same name are not interchangeable by appearance across RKF configurations, chain sizes, inboard/outboard arrangements or installation sides. Check dimensional relationships, materials and function.
Track Chain Link
Links transmit traction with pins, bushings and pan connectors. Check FLS chain size D4–D10, inboard or outboard arrangement, pitch, track width, mounting distance, connecting holes and lubrication type.
View Part Details →
Chain Pin and Bushing
Pins and bushings form chain joints and withstand alternating bearing pressure. Check pin and bushing diameters, length, interference, end retention, lubrication structure, link model and mating clearance.
View Part Details →
Track and Return Roller
These rollers support loaded track chains and return chains, maintaining their running path. Check roller diameter and width, shaft diameter, mounting distance, bearings, seals, lubrication, load/return side and frame interfaces.
View Part Details →
Drive Sprocket / Tooth Segment
Sprockets mesh with the track chains to transmit drive torque. The current FLS design uses replaceable bolted tooth segments. Check tooth count, pitch, tooth profile, installation side, hub, hole pattern, shaft fit and chain size.

Hydraulic-assisted Take-up
These devices adjust chain tension and compensate for track chain wear. Check travel, thrust, left/right side, slide, cylinder, pins, guides, stops and actual chain elongation.
View Part Details →Current documents define it as a heavy-duty apron feeder customized to project conditions. Published data cover width, length, chain, inclination, speed and power ranges. Identify documented configurations through project records.
No. Also check the complete configuration, serial number, chain size, inboard/outboard arrangement, pitch, mounting distance, pan overlaps, hole patterns, drawing revision and actual operating conditions.
Provide the complete configuration, serial number, chain size, inboard/outboard arrangement, drawings or samples, used-part photos, critical dimensions, material and operating conditions. We use these to identify parts, assess materials, match manufacturing requirements, control quality and deliver finished components.
