Heavy-Duty Plastic Waste Crusher

Product Overview

The plastic crusher is a high-efficiency, compact crushing equipment designed for reducing plastic materials (e.g., scraps, defective products, waste packaging) into small, uniform particles. Featuring a rotating blade system (with high-hardness blades) and fixed counter blades, it uses shearing and impact forces to break down plastic materials—even those with complex shapes (e.g., plastic bottles, injection molding runners). Unlike heavy-duty double-shaft shredders, this crusher is smaller in size (suitable for workshop installation) and lower in power consumption, making it ideal for small-to-medium-sized plastic processing plants, recycling centers, and injection molding facilities. It is widely used for on-site recycling of plastic waste, reducing material waste and lowering raw material costs.

Product Features

Blade Configuration: Adopts 6-12 piece SKD11 steel blades (with HRC 60-62 hardness—higher than standard CR12 blades) arranged in a staggered pattern to ensure efficient shearing. Each blade is secured with high-strength bolts (resistant to vibration loosening) and can be rotated 4 times (using all 4 cutting edges) before replacement, extending service life. The fixed counter blades are adjustable (via adjusting screws) to maintain optimal clearance with rotating blades (0.5-1.0mm), ensuring consistent crushing efficiency.

Crushing Chamber: Reinforced steel chamber (with 12mm thick steel plates) featuring a smooth inner surface to prevent material accumulation. The chamber’s large feed opening (200×300mm to 500×600mm, depending on model) allows easy feeding of large plastic scraps (e.g., 1m-long pipe sections) without pre-cutting. A sound insulation layer (5mm thick) is added to the chamber outer wall, reducing operating noise by 10-15dB compared to uninsulated models.

Screen Design: Quick-release screen (with latch-type installation) featuring aperture sizes from 3-20mm—allowing operators to adjust output particle size based on needs (e.g., 3-5mm for regranulation, 10-20mm for temporary storage). The screen is made of manganese steel (with high wear resistance) and can withstand high impact forces from crushing, with a service life of 2000+ working hours.

Dust Collection: Built-in cyclone dust collector (with a 50L dust bucket) offering 95% dust removal efficiency—capturing fine plastic dust generated during crushing to improve workplace air quality. The dust collector is connected to the crushing chamber via a flexible hose, and the dust bucket can be easily removed for disposal or recycling of fine dust (which can be mixed into raw materials for reprocessing).

Applications

Injection Molding Waste: Crushes sprue runners, gate scraps, and defective injection molding products (e.g., plastic toys, household appliances parts) into small particles for immediate reuse in production. The high crushing efficiency (100-1000kg/h) ensures minimal waste accumulation, with a recycling rate ≥95%—reducing raw material costs by 10-15% for injection molding plants.

Plastic Film Processing: Shreds PE and PP films (e.g., agricultural mulch film, packaging film) into small flakes (with size 5-10mm) for subsequent regranulation. The crusher’s low-speed operation (300-500rpm) prevents film winding around the blades (a common issue with high-speed crushers) and minimizes material melting, preserving the film’s mechanical properties.

Pipe and Profile Recycling: Crushes PVC pipes, UPVC profiles (e.g., window frames, door panels), and PE water pipes into uniform particles (size uniformity ≥90%) for reprocessing into new pipes or profiles. The crusher’s adjustable screen allows customization of particle size to match the requirements of downstream extrusion equipment (e.g., smaller particles for thin-walled pipes, larger particles for thick-walled profiles).

FAQ

Q: What is the noise level of the crusher during operation?

A: Standard models produce ≤85dB(A) (equivalent to the noise of a normal conversation), which complies with industrial workplace noise standards (GBZ 2.2). Silent versions—equipped with an additional sound insulation cover (10mm thick) and shock-absorbing feet—reduce noise to ≤75dB(A), making them suitable for use in indoor workshops with strict noise requirements.

Q: How to handle material jamming in the crushing chamber?

A: The machine is equipped with a reverse function (activated via a button on the control panel); press the reverse button for 5-10 seconds to clear jams by reversing the blade rotation. If jamming persists, stop the machine, open the safety cover (after ensuring power is disconnected), and manually remove the stuck material. To prevent jamming, avoid feeding oversized or hard foreign objects (e.g., metal, stones) into the crusher.
