Deploys Advanced Charcoal Briquetting Line to Shanxi, China

Zhengzhou, China – Chengjinlai Machinery, a globally recognized innovator in sustainable biomass solutions, has commissioned a fully automated turnkey charcoal production line for a major client in Shanxi Province. The integrated system—spanning crushing, molding, drying, and packaging—establishes new benchmarks in operational efficiency, energy conservation, and product quality for China’s burgeoning biofuel sector.

 

Core Advantages of the Production Line:

1. High-Efficiency Crushing Unit

   • Equipped with heavy-duty dual-shaft shredders and fine-grinding mills, processing 3–5 tons of raw biomass (sawdust, rice husk, coconut shells) per hour.

   • Intelligent moisture control ensures optimal particle size uniformity (<3mm), critical for consistent briquette density.

2. Intelligent Briquetting System

   • Hydraulic press machines generate 200+ tons of pressure, transforming powdered biomass into high-density hexagonal/pillow-shaped briquettes (8–10 cm) without binders.

   • Auto-lubrication and wear-resistant alloy molds extend maintenance cycles by 40%, reducing downtime.

3. Energy-Saving Mesh Belt Dryer

   • Three-tier stainless-steel conveyor dryer with precise temperature control (80°C–120°C) reduces moisture from 35% to <8% in 2–3 hours.

   • Heat recovery technology cuts energy consumption by 30% versus conventional dryers.

4. Automated Packaging & Quality Control

   • Weighing-filling-sealing machines pack 15–20 bags (25kg each) per hour with ±0.2% weight accuracy.

   • Integrated metal detectors and rejection systems guarantee export-grade product integrity.

Integrated Performance Benefits

• Output Boost: Processes 4.5 tons of raw material hourly, yielding 3+ tons of premium briquettes.

• Labor Reduction: Fully automated controls cut manpower requirements by 60%.
• Eco-Compliance: Dust collectors and noise-dampening designs meet China’s GB16297 emission standards.

Engineering Excellence: Core System Advantages

1. Intelligent Preprocessing Unit

   • Dual-Stage Crushing Technology: Primary shredders with 55kW motors process 6+ tons/hour of irregular biomass (e.g., tree branches, coconut shells), while secondary micro-grinders achieve ultrafine <2mm particles with moisture sensors maintaining optimal 12-15% hydration.

   • Zero-Waste Design: Integrated cyclone separators capture 99.8% of airborne dust, redirecting particles into production flow.

2. High-Pressure Briquetting System

   • Hydraulic Molding Presses: Generate 320 tons of compressive force through ISO-certified alloy dies, producing 3,500±50 briquettes/hour (hexagonal/pillow shapes) with uniform density (≥1.2 g/cm³) and smokeless combustion properties.

   • Self-Optimizing Controls: AI-driven pressure adjustment compensates for material variability, reducing cracks and ensuring 98.5% structural integrity.

3. Patented Three-Zone Drying Tunnel

   • Staged Thermal Management:
     ∙ Zone 1 (80°C): Gentle moisture reduction prevents surface hardening
     ∙ Zone 2 (110°C): Core dehydration via horizontal airflow
     ∙ Zone 3 (70°C): Stabilization cooling

   • Energy Recovery System: Condensed steam reheats incoming air, slashing thermal energy consumption by 42% versus conventional dryers.

4. Robotic Packaging Suite

   • Automated Quality Gate: X-ray detection scans for density anomalies while metal sensors screen contaminants at 25 units/minute.

   • Precision Bagging: Servo-controlled filling achieves 0.1% weight tolerance with automatic palletizing for export-ready stacking.
