The client is a citizen cooperative based in Guinea, West Africa, engaged in plastic waste collection and recycling. The cooperative collects post-consumer plastic waste from local sources, sorting it into categories including HDPE (jerrycans, bottles), PP (buckets, basins, crates), PET (water bottles, soft drink bottles), and mixed automotive plastics. To process the collected rigid plastics into smaller pieces for further recycling, the cooperative ordered a plastic bottle crusher machine from Henan Shuliy Machinery.

Client requirements

The cooperative needed a plastic bottle crusher machine capable of handling diverse rigid plastics commonly found in West African waste streams:

  • HDPE jerrycans and chemical containers
  • PP buckets, basins, and crates
  • PET water and soft drink bottles
  • Mixed plastics including bottle caps and automotive parts

The site power supply is 380V, 50Hz, 3-phase. The required output size is 15mm, suitable for downstream washing or direct melting.

Equipment Configuration

The plastic bottle crusher machine shipped to Guinea is a single SL-600 unit — a compact, standalone crusher designed for rigid plastics:

사양세부사항
모델SL-600
전력22kW
용량600–800 kg/h
Knives10 pcs (6 movable + 4 fixed)
날 재료60Si2Mn alloy steel
Screen size15mm
치수1200 × 700 × 1600 mm
전압380V / 50Hz / 3-phase

Why 60Si2Mn Blades Matter

The SL-600 uses 60Si2Mn alloy steel blades — a manganese-silicon spring steel known for high hardness and impact resistance. For a plastic bottle crusher machine processing mixed rigid plastics, blade material is the single biggest factor in service life and maintenance cost.

HDPE and PP containers can be thick-walled and tough. PET bottles are brittle but create sharp edges that chip inferior blades. 60Si2Mn holds its edge significantly longer than standard carbon steel, reducing blade replacement frequency and keeping output particle size consistent.

15mm Screen Output

The 15mm screen determines the maximum particle size after crushing. This size is suitable for:

  • Direct feeding into a friction washer for further cleaning
  • Melting in a single-stage extruder for lower-grade pellets
  • Baling and selling to larger recyclers

Why This Client Chose Shuliy Machinery

  1. Right capacity for a startup cooperative. 600–800kg/h fits a small-to-medium collection and recycling operation — not oversized, not underpowered.
  2. Handles mixed rigid plastics. HDPE, PP, PET, and automotive plastics all in one machine. The cooperative doesn’t need separate crushers for different material types.
  3. 60Si2Mn blades as standard. Many crushers in this price range use carbon steel blades that wear quickly. 60Si2Mn is a meaningful upgrade for operations running multiple shifts.
  4. 15mm screen matched to downstream process. Output size ready for washing or direct reprocessing.
  5. Spare blades included. Essential for operations in West Africa where replacement parts cannot be sourced locally.
  6. CIF delivery to Conakry. Shuliy handles port-to-port shipping, reducing the client’s logistics complexity.
