Confirm the installation by D4, D7, D10 or D11 type and working width, then identify pans, impact liners, chains, sprockets, support rollers and tensioning spares.
MMD apron feeders withstand direct dumping of coarse lumps and feed downstream equipment steadily. This page covers wear parts, chain drives and manufacture to drawing. Length, material, capacity and drive configuration are project-specific.
Dimensions follow MMD's official apron feeder product page. Width and height support initial identification; length and final configuration are customized for material, capacity, density and project requirements.
| Type | Overall width | Overall height | Effective conveying width |
|---|---|---|---|
| D4 Type | 2160 mm | 1200 mm | 1500 mm |
| D7 Type | 2775 mm | 1480 mm | 2000 mm |
| D10 Type | 3990 mm | 1960 mm | 3000 mm |
| D11 Type | 5025 mm | 2260 mm | 4000 mm |
Before manufacturing pans, chains or drive parts, check complete model, serial number, chain pitch, effective width, general arrangement, component drawings and drawing revision.
Separate pans, receiving-area impact plates, side liners, head and tail liners, and return drip pans by position, with links to common-part and material pages.
Apron Pan / Feeder Plate
Continuously receive large-lump impact and form the conveying surface. Confirm pan width, section, connecting holes, overlap and chain pitch against the D type and drawings.
Material selection: MMD specifies heavy-duty rolled plate construction. Confirm base material, welding, wear layers and heat treatment against original drawings and impact conditions.

Impact Plate
At direct-tipping and impact-attenuation positions, these protect the main structure and spread lump impact. Confirm profile, thickness and retention by location.
Material selection: Prioritize impact toughness, resistance to plastic deformation and replaceability. Confirm grade and composite construction against service conditions and drawings.
View the common part page →
Side Liner / Skirt Liner
Along both sides of the conveying path, liners contain material and protect walls. Check mounting holes, overlaps, clearances and relative motion with the pans together.
Material selection: Select wear plate or replaceable cast liners for sliding abrasion, lump impact and thickness limits.
View the common part page →
Head Discharge Chute Liner
At the head discharge and flow-turning area, liners withstand impact and sliding abrasion. Confirm material trajectory, liner zones, connections and replacement access.
Material selection: Select wear plate, composites or local reinforcement for the balance of impact and sliding abrasion.
View the common part page →
Tail Inlet Liner
Protect the tail feed and drop-zone boundaries. Check drop height, lump size, flow direction and clearance to adjoining moving pans.
Material selection: Select material and thickness together for impact energy, abrasiveness, structural support and replacement interval.
View the common part page →
Drip Pan Liner
Below the return run, pans collect spillage and protect the bottom structure. Confirm shape, joints, discharge direction and cleaning access against the machine layout.
Material selection: Sliding abrasion and maintainability usually dominate. Confirm materials against original drawings, handled material and service-life requirements.
View the common part page →Drive parts are listed separately. Chain pitch, pin/bushing fits, sprocket tooth profiles and roller bearings must be checked together for the same machine.
Chain Link
Core traction-chain members transmit continuous tension and impact loads. Confirm pitch, hole spacing, plate thickness, heat treatment and matched-set requirements.
Material selection: Follow original drawings and design loads for link material, forging or casting, heat treatment and nondestructive testing.
View the common part page →
Chain Pin & Bushing
Form the link articulation and take contact fatigue, wear and impact. Check pin diameter, bushing wall thickness, fits, lubrication and hardened layers together.
Material selection: Alloy steel, surface hardening and core toughness are key controls. Drawings determine the actual parameters.
View the common part page →
Drive Sprocket
Mesh with the traction chain to transmit torque. Confirm tooth profile, pitch, tooth count, hub interface and mounting direction together with chain and shafts.
Material selection: Confirm tooth-surface strength, wear layer, core toughness, tooth accuracy and nondestructive testing against drive requirements.
View the common part page →
Support Roller
Support moving pans and traction chains, affecting running resistance, chain alignment and pan stability. Identify shaft, roller body, bearings and seals as an assembly.
Material selection: Confirm roller bodies, shafts, bearings and seals separately for load, speed, contamination and lubrication.
View the common part page →
Chain Tensioner
Compensate chain elongation and maintain suitable tension. Confirm travel, load direction, hydraulic or mechanical interfaces and locking structure against the machine layout.
Material selection: Confirm structures, shafts, bushings and seals separately for load and tensioning method.
View the common part page →No. Also confirm effective width, machine length, chain pitch, pan profile, fastening holes, serial number and drawing revision.
They may be manufactured separately, but technical review should cover the matched system to prevent mismatched pitch, tooth profiles, fits and running paths.
Traceable information does not yet establish a sufficiently reliable part-number mapping for D4, D7, D10 and D11. Unverified numbers are not presented as confirmed data.
Provide D type, serial number, effective width, chain pitch, part position, drawings or samples, materials and operating conditions. We use these for identification, manufacturing coordination, quality control and delivery.
