Basic Structure
Chain Body Heavy-duty plate conveyor chain constructed with thickened inner & outer link plates, solid pins, sleeves and support rollers. Normally made of high-strength carbon steel with heat treatment for enhanced wear resistance; stainless steel is optional for corrosive environments. Thick link plates provide high tensile load for long-time heavy-load traction.
Custom Attachments Two common attachments: L-shaped scraper brackets and cylindrical hook attachments. Scrapers are welded or bolted onto attachments to push materials during operation. Attachment dimensions and spacing can be customized according to equipment drawings.
Support Rollers External support rollers run along the machine guide rail to reduce friction, lower power consumption and mitigate wear on link plates.
Flight & Scraper Types
- Designed Flight and Scraper Systems for En-Mass Management
H&H provides precisely developed flight attachments tailored to your bulk material characteristics to reduce wear and prevent material slide during high-capacity horizontal or inclined conveying: -
Flight Profile Structural Feature Hardfacing & Material Options Primary Applications U-Type Scraper Curved profile tailored for high trough filling rates (up to 80%). High-Mn Steel (Mn13) / Tungsten Carbide Hardfacing Grain, Pellets, Fine Powders, Fly Ash V-Type / Bent Scraper Reinforced V-shape design with enhanced stiffness for inclined conveying. Quenched & Tempered Alloy Steel + Anti-wear Welded Layer Cement Clinker, Coal Powder, Ore Concentrate Straight Flat Scraper Heavy-wall flat steel plate with optional non-metallic wear strips. Mn Steel / UHMW-PE Wear Liner Options Biomass, Shredded Materials, General Bulk
Customization Notice: All flight attachments are forged or precision-welded directly to the chain links to prevent weld fatigue during continuous heavy-load operations.
Applications
Specially designed for FU en-masse scraper conveyors. Suitable for closed transportation of fly ash, cement, grain, wood chips, mineral powder, chemical powder and granular materials. Widely used in building materials, grain processing, metallurgy, chemical industry and environmental dust removal projects.
Selection & Technical Guide
Guide to Selection: Chart of Capacity versus. Chain Speed
The material bulk density, throughput capacity, and operation speed all influence the choice of FU conveyor chain pitch and scraper size. For quick engineering evaluation, use the matrix below:
| Chain Model | Pitch (P) | Trough Width | Recommended Max Speed | Throughput Range (Bulk Density 0.8−1.5 t/m3) |
Tensile Strength (KN) |
| FU 150 | 100 mm | 150 mm | ≤0.35 m/s | 6−15 m3/h | ≥80 KN |
| FU 200 | 125 mm | 200 mm | ≤0.40 m/s | 15−35 m3/h | ≥120 KN |
| FU 270 | 160 mm | 270 mm | ≤0.45 m/s | 30−70 m3/h | ≥200 KN |
| FU 350 | 200 mm | 350 mm | ≤0.50 m/s | 60−130 m3/h | ≥320 KN |
| FU 410 | 200 mm | 410 mm | ≤0.50 m/s | 100−200 m3/h | ≥450 KN |
| FU 600 | 250 mm | 600 mm | ≤0.40 m/s | 180−350 m3/h | ≥600 KN |

Why Choose H&H FU Drag Scraper Chains?
Advanced Induction Heat Treatment Chain pins and bushes undergo multi-stage heat treatment to achieve a surface hardness of HRC 55–60 with a deep carburized case depth, significantly extending service life in highly abrasive cement and mining environments.
Zero-Jamming Flight Design Our FU drag scraper chain link plates feature optimized chamfered edges and tight-tolerance pin holes, ensuring seamless interaction with drive sprockets and preventing material buildup inside the trough.
High-Strength Manganese & Hardfaced Scrapers Scrapers are fabricated from Mn13 high-manganese steel or augmented with anti-wear hardfacing welds, offering up to 2.5x longer operational lifespan compared to standard carbon steel scrapers.
