A plastic crusher (or shredder) is a machine designed to break down plastic waste into smaller pieces for recycling or reprocessing. It is widely used in:
✅ Plastic recycling plants
✅
Manufacturing facilities
✅ Waste management centers
Reduces plastic waste volume by 50-90%
Prepares materials for washing, extrusion, or pelletizing
Available in different sizes and power options
Best for: PET bottles, thin-walled plastics
Advantages: Simple structure, easy maintenance
Capacity: 0.5–3 tons/hour
Best for: HDPE barrels, tough plastics
Advantages: High torque, handles thick materials
Capacity: 2–8 tons/hour
Best for: Urban recycling stations
Advantages: Noise <75 dB, enclosed design
Capacity: 1–4 tons/hour
Feeding: Plastic waste is fed into the crushing chamber.
Cutting: Rotating blades shear and shred the plastic.
Screening: Crushed pieces pass through a sieve (10-50mm holes).
Discharge: Processed plastic is collected for further recycling.
✔ Blades (SKD-11 alloy steel)
✔ Motor (7.5–75 kW, depending on model)
✔ Sieve (Screen Mesh) – Controls output size
✔ Control Panel – Adjusts speed and operation
| Factor | Consideration |
|---|---|
| Material Type | PET, HDPE, PP, etc. |
| Input Size | Large blocks or small pieces? |
| Output Size | 10mm, 20mm, or customized? |
| Capacity | 0.5T/h, 5T/h, or higher? |
| Power Supply | 220V, 380V, or diesel-powered? |
Small crusher (7.5 kW): 6,000
Medium crusher (22 kW): 15,000
Large crusher (55 kW+): 50,000
✔ Check blade sharpness
✔ Lubricate bearings
✔ Clean the crushing chamber
| Issue | Possible Cause | Solution |
|---|---|---|
| Low output | Dull blades / Clogged sieve | Replace blades / Clean sieve |
| Strange noise | Loose parts / Bearing damage | Tighten bolts / Replace bearing |
| Motor overheating | Overloading / Poor ventilation | Reduce load / Improve cooling |
