Product use :

1.Agricultural Applications

Grain & Feed Handling

• Grain Elevators – High-capacity forged chains for vertical grain transport (wheat, corn, soybeans)
  Feed Conveyors – Corrosion-resistant chains for livestock feed distribution systems
  Fertilizer Spreaders – Wear-resistant scraper designs for abrasive fertilizer materials

Harvesting & Processing

• Combine Unloading Systems – Heavy-duty chains for continuous grain flow during harvest
  Seed Cleaning Lines – Precision-forged links to prevent seed damage
  Sugar Beet/Cane Transport – Reinforced attachments for high-moisture crop handling

2. Mining & Mineral Processing

Bulk Material Transport

• Coal/Ore Conveyors – Tungsten-carbide reinforced chains for abrasive materials
  Slurry Handling – Sealed pivot joints to prevent contamination from wet minerals
  Rock/Stone Processing – Extra-thick sidebars (up to 30mm) for impact resistance

Processing Plants

• Crusher Feed Systems – Shock-absorbing chain designs for uneven material intake
  Screening Plant Transfer – Low-maintenance chains for vibrating conveyor applications
  Tailings Removal – Acid-resistant coatings for mine waste handling

3. Industrial Material Handling

• Biomass Energy Plants – High-temperature chains (up to 250°C) for wood chip conveyors
  Recycling Facilities – Magnetic-proof chains for scrap metal sorting lines
  Cement/Slag Transport – Abrasion-resistant flight attachments

FAQ :

1. What makes your forged scraper chains more durable than standard chains?

Material Strength: Made from AISI 4140/4340 alloy steel (3× higher fatigue resistance than cast chains).
Forging Process: Hot drop forging ensures denser grain structure, reducing crack propagation.
Surface Treatments: Optional induction hardening (HRC 55+) or tungsten carbide overlay for extreme abrasion resistance.

2. What agricultural applications are these chains best suited for?

• Grain elevators & silo feed systems

• Fertilizer/seed conveyors

• Sugar beet/cane transport

• Key Benefit: Self-cleaning scraper design prevents material buildup in high-moisture conditions.

3. How do your mining-grade chains handle abrasive materials?

• Hardened flight bars (Brinell 400+)

• Sealed pivot joints to keep out ore particles

• Replaceable wear strips for easy maintenance

• Performance: 8,000+ hours in copper ore conveyors (documented case study available).

4. Can you match existing OEM chain specifications?

• Reverse engineering via 3D scanning of worn parts
• Matches RUD, PEER, IWIS and other major brands
• Custom pitch/width adjustments (±2mm tolerance)

5. What’s the maximum load capacity?

• Breaking load: Up to 250kN (size-dependent)
• Working load: 30% of breaking load for safety
• Temperature range: -40°C to +200°C
