Forged Agricultural Conveyor Roller Chain Logistics Scraper Chain Farming Conveyor Chain

Product Overview :

Scraper chains (also called drag chains or flight chains) are heavy-duty conveyor systems designed for material handling in demanding industrial environments. They consist of forged chains with attached scrapers/flights that push, drag, or carry bulk materials along a trough or pipe.

Technical parameters :

1. Material & Construction

• Chain Material:
  • Carbon Steel: Grade C45, 1045 (standard duty)
  • Alloy Steel: 4140, 42CrMo4 (high-strength applications)
  • Stainless Steel: 304, 316 (corrosive/wet environments)
• Forging Process: Precision hot forging + heat treatment
• Surface Treatment:
  • Zinc-plated (standard)
  • QPQ (Quench-Polish-Quench) for extreme wear resistance
  • Self-lubricating coatings (option)

2. Mechanical Properties

3. Dimensional Specifications

• Chain Types Available:

  • Roller Chains: ANSI/DIN standard sizes (40-240 series)

  • Scraper Chains: With integrated flights (50-400mm width)

  • Drag Chains: Heavy-duty enclosed designs

• Pitch Range: 25.4mm (1") to 152.4mm (6")

• Flight/Scraper Options:

  • UHMWPE flights (abrasion-resistant)

  • Rubber-edged scrapers (gentle on grains)

  • Steel flights (for heavy debris)

Product advantages :

1. Superior Durability
Forged Construction : Tensile strength is increased by 30% and fatigue life is extended by 2 times compared to ordinary casting chains

Enhanced Heat Treatment (Enhanced Heat Treatment) : The use of tempering + surface quenching process, the chain hardness of 40-55HRC

Wear Resistance : Pin plated hard chromium/tungsten carbide treatment, in grain/feed transport life of more than 5 years

2. Professional Agricultural Optimization
Anti-Clogging : Large roller design (≥30mm) to prevent straw/husk from getting stuck

Corrosion Protection :

Salt spray test 1000 hours (galvanized version)

The 316L stainless steel version is suitable for highly corrosive environments such as organic fertilizers

Low Maintenance design : Self-lubricating bushing is optional, and the filling cycle is extended to 500 hours

3. High Efficiency
High Incline : Special grab scraper design, tilt Angle up to 60° (conventional chain 45°)

Material Versatility :

Grain/Feed (Rubber edge scraper)

Organic fertilizer (all stainless steel chain)

Straw/Biomass (Reinforced alloy steel)

Variable Speed : Support 0.1-2m/s speed regulation (standard type)

FAQ :

1. What makes your forged chains better than standard roller chains?

• Material Strength: Hot-forged alloy steel provides 30% higher tensile strength than cast chains.

• Extended Lifespan: Precision heat treatment extends service life to 5-8 years in abrasive conditions (e.g., grain/sand handling).

• Custom Wear Protection: Optional tungsten carbide coatings reduce wear in high-abrasion applications like fertilizer conveying.

2. How do I select the right chain for my agricultural equipment?

• Material Type: Stainless steel (316L) for corrosive environments (manure/fertilizer), carbon steel for dry grains.

• Chain Pitch: Standard pitches (e.g., ANSI #40-#240) or custom lengths.

• Attachment Style: Choose flights/scrapers based on material (rubber edges for grains, steel scrapers for biomass).
  Pro Tip: Share your conveyor slope and tonnage requirements for tailored recommendations.

3. Are your chains compatible with existing OEM equipment?

• • ANSI/DIN/ISO standard dimensions (e.g., 1" to 6" pitch).

  • Brand-matching: Custom-fit replacements for John Deere, CLAAS, etc.

• Provide your old chain samples or sprocket specs for guaranteed compatibility.

4. How do you ensure corrosion resistance?

• Standard: Zinc plating (500+ hour salt spray resistance).

• Premium: QPQ treatment or 316L stainless steel for acidic/organic material handling.
