Product Introduction: Dragon Bone Chain & Keel Chain Sprocket System
Product Name
Dragon Bone Heavy-Duty Conveyor Chain with Precision Keel Sprockets
Category
Belt Conveyor Drive Components
Product Overview
Engineered for extreme-load material handling, our Dragon Bone Chain and Keel Sprocket system redefines reliability in mining, bulk processing, and heavy-industry conveyors. The patented interlocking “dragon bone” link design distributes impact forces across multiple contact points, while hardened keel sprockets ensure zero-slip power transmission under 200-ton/hour operational stress.
Core Technology
Dragon Bone Chain
Multi-Axial Load Distribution: Triple-hinged links absorb shock loads 3X better than standard chains
Corrosion Immunity: Hot-dip galvanized/Zinc-nickel alloy coating (ISO 1461)
Self-Cleaning Design: Scraper-integrated links prevent debris buildup
Ultimate Tensile Strength: 100–300 kN (customizable)
Precision Keel Sprockets
Anti-Wear Teeth: Laser-hardened 55–60 HRC surface with PTFE infusion
Zero-Misalignment Hub: Keyed + taper-lock mounting (ISO 773)
Intelligent Wear Indicators: Embedded RFID tags monitor tooth degradation
