Technical Excellence
Engineered to Resist Acidic Corrosion, Sand Wear & High Load
Crude Palm Oil (CPO) acid combined with silica sand creates an aggressively abrasive and corrosive environment. Standard chains fail rapidly due to pin wear and link plate fracture. HH Chains addresses these challenges through targeted metallurgical engineering:
1. Induction-Hardened Pins & Bushings
Deep case depth hardening via precision induction treatment.
Creates a super-hard outer wear surface while preserving a ductile core to absorb sudden shock loads from heavy FFB drops.
2. Thickened Alloy Steel Sidebars & Seamless Rollers
High-grade alloy steel (40Cr / 20CrMnTi) plates engineered with increased wall thickness to prevent fatigue cracking under continuous high-tension loads.
Seamless solid rollers reduce surface friction and sprocket wear under heavy slurry conditions.
3. CPO Acid-Resistant Protective Coatings
Optional specialized surface coatings (Zinc-Nickel plating, Dacromet, or specialized phosphate treatment) to neutralize the corrosive impact of fatty acids and high humidity.
FAQ
-
Q1: What is the most common chain model for Palm Oil Mill FFB feeders?
A: The ES4P23 and 40150/40200 series are widely recognized standards for FFB conveyors and fruit feeders due to their high tensile strength and pitch stability under heavy impact.
Q2: How do you prevent chain elongation in high-sand palm oil processing environments?
A: We utilize high-frequency induction hardening on pins and bushings, along with tight manufacturing tolerances on pitch holes, effectively reducing pin-bush wear and preventing premature chain elongation.
