Expert Guide to Calcium Oxide Briquette Machine Mold Restoration – Maximize Your Quicklime Pelletizing Efficiency

Is your quicklime briquetting machine suffering from frequent mold wear? Worn-out molds in lime powder briquetting machines can lead to production delays, uneven pellet quality, and increased maintenance costs. This article reveals proven strategies to restore and extend the lifespan of your calcium oxide briquette machine molds while optimizing operational efficiency.

Why Do Calcium Oxide Briquette Machine Molds Wear Out?

Mold degradation in industrial lime briquette presses often results from:

• Abrasive materials: High friction from quicklime (CaO) or hydrated lime powders.
• High-pressure operations: Continuous compression exceeding 1000-ton force.
• Thermal stress: Repeated heating-cooling cycles during pelletizing.
• Material impurities: Unfiltered debris in lime powder accelerating wear.

Step-by-Step Mold Restoration Solutions

Professional Surface Regrinding

For mildly worn molds in quicklime pellet machines, precision CNC grinding can restore surface smoothness and dimensional accuracy. Ideal for molds with ≤0.5mm wear depth.

Laser Cladding for Severe Damage

Repair deep grooves (＞1mm) using chromium carbide laser cladding – a 3X longer lifespan than original molds. Compatible with high-density calcium oxide briquette machines.

Anti-Wear Coatings

Apply tungsten carbide coatings to critical contact areas. Reduces friction by 40% in lime powder compaction systems.

Preventive Maintenance Protocol

• Clean molds weekly with compressed air to remove lime residue.
• Lubricate with high-temperature graphite spray (safe for CaO processing).
• Monitor pressure via IoT-enabled sensors to avoid overloads.

Upgrade Options for Long-Term Performance

• Dual-layer alloy molds: Combines 65Mn steel base with Ni-Cr surface treatment. Withstands 8,000+ hours in steel plant desulfurization lime pellet lines.
• Modular mold designs: Replace single worn modules instead of full molds. Cuts downtime by 70% for 24/7 quicklime briquetting operations.
• Automated mold cleaning systems: Integrated rotary brushes prevent material buildup in hydrated lime pellet presses.

Case Study: Reviving a 3000TPD Quicklime Pellet Plant

A Vietnamese steel mill using CaO briquetting machines faced weekly mold replacements. Our solutions:

• 1.Applied laser-hardened mold inserts for high-abrasion zones.
• 2.Installed real-time pressure monitors to optimize compression.
• 3.Switched to binder-free lime briquetting technology.
  Result: Mold lifespan increased from 15 to 90 days, saving $12,000/month.
