The Ultimate Guide to Plastic Bottle Crusher Full Set Equipment: Efficient Recycling Solutions

Understanding Plastic Bottle Crusher Full Set Equipment

Core Components of a Full Set Equipment

1. Crushing Module:
   • Single-Shaft Crushers: Ideal for soft PET bottles, these machines use rotating blades to reduce bottles into 3–10 mm flakes, with outputs ranging from 50–500 kg/h .
   • Dual-Shaft Crushers: Handle rigid plastics and mixed waste through shear forces, processing 200–2,000 kg/h. Their carbide-tipped blades minimize wear and maintenance .
   • Hydraulic Crushers: High-throughput systems (up to 5,000 kg/h) for large-scale operations, using hydraulic rams to compress and shred bottles .
2. Washing and Cleaning Module:
   • Friction Washers: Remove labels, adhesives, and contaminants through high-velocity water jets and mechanical scrubbing.
   • Hot Water Tanks: Use detergent solutions to dissolve residues, ensuring flakes meet food-grade purity standards .
3. Dehydration and Drying Module:
   • Centrifugal Dryers: Reduce moisture content to <5% using high-speed rotation, preparing flakes for pelletization.
   • Conveyor Dryers: Use heated air to achieve uniform drying, critical for maintaining material consistency .
4. Pelletizing Module:
   • Extruders: Melt cleaned flakes into molten plastic, which is then extruded into pellets. Modern systems achieve pelletizing rates of 80–150 kg/h with energy consumption as low as 0.5 kWh/kg .
