Identify pans, liners, chains, sprockets, rollers, head shafts, bearings and tensioning systems from the AF4–AF18 model, width and length. We coordinate drawing-based manufacture in China, quality control and finished-part delivery.
Metso's current apron-feeder documentation lists standard and project configurations from AF4 to AF18. ANRANST focuses on pans and receiving-zone wear parts, chains and sprockets, rollers, head shafts and bearings, tensioning and structural repairs. The generic name apron feeder is not enough to identify an installed machine.
Only standard models, widths and lengths needed for part identification are listed. Confirm throughput, drive power, inclination and hopper loads from project documentation.

| AF8 | Width 1,524–2,438 mm; length 8,000–12,200 mm | Preconfigured series |
| AF10 | Width 2,134–3,048 mm; length 8,800–13,000 mm | Preconfigured series |
| AF12 | Width 2,134–3,048 mm; length 8,800–13,000 mm | Standard modular range |
| AF14 | Width 2,438–3,353 mm; length from 10,000 mm | Length configured by width |

Assess impact, sliding abrasion and deformation separately at the pans, inlet, sidewalls, discharge, impact supports and spillage zones, then select materials, heat treatment and replaceable designs.
Pans / Flights
Pans directly withstand large-lump impact, compression and sliding wear. Metso's current brochure specifies cast high-manganese steel pans with bolted connections, lifting holes and wear indicators. Confirm profiles, hole positions and main/secondary pan combinations for the installation.
Side Liners / Skirt Liners
Installed along the material bed to limit side spillage and protect the hopper or walls. Distinguish large-lump impact zones, fine-material sliding abrasion and running clearance to the pans when selecting materials. The image illustrates the generic component category.
Tail / Inlet Liners
Located at the receiving and tail zones, these liners mainly face falling-material impact and wear from accumulated material. Check mounting profile, thickness, holes, overlaps and replacement access. The image illustrates the generic component category.
Head / Discharge Chute Liners
Located along the head-end discharge path and downstream chute connection, these liners face continuous scouring, local impact and fine-particle abrasion. Select materials and design by drop height, particle size, moisture and replacement interval. The image illustrates the generic component category.
Impact Rails / Impact Plates
Installed below the heavy-duty receiving zone to support pans and reduce permanent impact deformation. Metso's current brochure specifies hardened-steel impact beams. Confirm actual width, beam count and interfaces before manufacture. The image illustrates the generic component category.
Drip Pan Liners
Located under the return run and frame to collect material falling through pan gaps and protect the frame. Fine-particle abrasion and cleaning access dominate selection; consider removability, buildup and corrosion. The image illustrates the generic component category.
Check chains, sprockets, rollers, head shafts, bearings, tensioning and drive as one aligned system. Structural repairs also require checks of frame straightness, roller elevations and chain centre distance.
Chains / Chain Links
Metso's current brochure specifies tractor-type sealed and lubricated chains. Check chain specification, pitch, link design, connection method, left/right pairing and operating elongation.
View the general component guide →
Chain Pins & Bushings
Pins and bushings form the main wear pair at chain articulations. Confirm them together by chain series, mating dimensions, material, heat treatment, surface hardness and lubrication condition.
View the general component guide →
Drive Sprockets & Hubs
The brochure specifies hardened, reversible sprockets and separately machined hubs. Check tooth count and profile, keyways, hub fits and chain specification together.
View the general component guide →
Carry & Return Rollers
Carry rollers support the loaded run; return rollers support the returning chain and pans. Specify position, roller dimensions, shaft-end design, seals, lubrication and modular mounts in the enquiry.
View the general component guide →
Idler Tail Wheel & Take-up System
Metso's current brochure lists shaftless tail wheels, tensioning frames and hydraulic-cylinder or manual-screw tensioners. Confirm chain centre distance, stroke, mounting blocks and site adjustment method.
View the general component guide →Head Shaft, Bearings & Split Housings
The exploded view identifies head shafts, sprockets, hubs and bearings separately. The brochure specifies a forged high-alloy head shaft, spherical roller bearings and split housings. Confirm journals, splines, keyways and bearing models before manufacture.
View the general component guide →Reducer, Coupling & Motor
Manufacturer information lists planetary gearboxes, splined connections, motors and torque arms. ANRANST focuses on interface measurement, connecting and support parts, and project coordination. Confirm original drive units by nameplate and configuration.

Frame, Crossbeams & Roller Modules
The heavy-duty frame comprises main beams, crossmembers, impact beams and roller modules. Repair or replacement requires checks of overall straightness, chain centrelines, roller elevations, welded construction and site lifting conditions.
Send details for technical confirmation →Provide the AF model, nameplate or serial number, part or drawing, installed-part photographs, key dimensions, feeder width, chain specification and processed material.
No. The model only narrows the range. Confirm feeder width and length, main/secondary pan combination, holes, chain interfaces, drawing and actual dimensions.
The model, chain specification, assembly photographs and measurements can narrow the search. Before manufacture, confirm drawings, tooth profile, journals, keyways or splines and fit tolerances.
Browse component descriptions, drawing requirements and enquiry details.
Provide the nameplate, serial number, feeder width and length, chain specification, installed-part photographs, drawings, material and operating conditions. These support part identification, material assessment, production at certified foundries, quality control and finished-part delivery.
