Plastic Crusher

The Plastic Crusher is a high-torque rotary knife machine engineered to reduce large, bulky plastic scrap into small, uniformly sized flakes. It is the primary size-reduction workhorse in any plastic recycling, injection molding, or compounding operation. By cutting dense purgings, thick pipes, whole bottles, film rolls, and injection runners into 8–14mm regrind, the crusher slashes storage volume by up to 70%, eliminates expensive hauling of loose scrap, and delivers a consistent flake that flows perfectly into washing tanks, dryers, and extruder hoppers. With wear-resistant D2/SKD-11 alloy blades, an easily swappable sizing screen, and a fully welded heavy-gauge steel frame, our crusher runs reliably shift after shift, turning disposal headaches into a clean, saleable, or reusable material stream.

• Reduce Storage & Transport Costs by 70%: Bulky pipes, containers, and purgings are crushed into dense, pourable flakes, dramatically freeing up factory space and cutting waste hauling costs per ton.

• Uniform Flake Size for Smooth Downstream Processing: The interchangeable screen mesh (8–20mm) ensures every flake is dimensionally consistent. This prevents bridging in hoppers, improves washing efficiency, and guarantees stable feeding of pelletizing extruders.

• Universal Thermoplastic Compatibility: Our crushers handle the full range — from hard, rigid HDPE drums, PP crates, and ABS automotive parts to soft, flexible LDPE film, PP raffia bags, and PET bottles. The rotor geometry and screen are selected to match your specific feedstock.

• Long-Life D2/SKD-11 Blades, Low Operating Cost: The rotor and stationary blades are made from high-alloy tool steel (HRC58-62), staying sharp through hundreds of tons of grinding. Blades are adjustable and re-sharpenable multiple times, keeping annual replacement costs minimal.

• Wet & Dry Crushing Available: Dry crushing is standard for clean factory scrap. For post-consumer films, PET bottles, and printed waste, the wet crushing option adds a water spray system that pre-cleans the material, cools the blades, and suppresses dust, extending blade life.

• Soundproof, Safety-Interlocked Design: Optional soundproof enclosures reduce operational noise to below 80 dB(A), suitable for urban recycling centers. An interlocked hopper door, emergency stop button, and thermal overload relay ensure operator safety at all times.

• Built for Non-Stop Industrial Duty: A thick welded steel frame, oversized heavy-duty bearings, Siemens/ABB motor, and V-belt drive with overload protection give you a crusher that thrives under continuous, demanding conditions.

Proven Performance in Real Recycling Operations
Based on after-sales data from 200+ crusher installations at injection molders and recycling plants (2022–2024):

• Volume Reduction by 70%, Hauling Costs Cut in Half: Factories crushing bulky waste on-site report an immediate 70% reduction in storage space and a 50–60% drop in waste disposal expenses.

• Higher Washing & Extrusion Throughput: Uniform 10–12mm flakes from our crushers boost washing line efficiency by up to 30% and eliminate extruder feed blockages, directly increasing pellet output.

• Blades Last 200–500 Tons Between Sharpenings: D2/SKD-11 tool steel blades consistently achieve long service intervals, keeping yearly blade costs under 3% of the machine’s price.

• Payback in 3–6 Months for Injection Molders: By grinding sprues and rejects directly beside the press for immediate reuse, molders recover the full crusher cost within half a year through virgin material savings alone.

• Wet Crushing Improves Flake Cleanliness by 20%: Recycling operations running post-consumer film and bottles with our wet crushing system report cleaner flakes and lower water consumption in downstream washing stages.

Applications: What Can You Crush?
Our Plastic Crusher is the universal size-reduction solution for:

• Injection & Blow Molding Scrap: Sprues, runners, rejected parts, start-up lumps — grind at the press for closed-loop material recovery.

• Post-Consumer Containers: PET water/soda bottles, HDPE milk/shampoo jugs, PP food tubs and buckets. Produce consistent flakes for hot-wash and pelletizing lines.

• Industrial & Construction Plastics: HDPE/PP pipes and fittings, PVC window profiles and pipes, ABS electronic/automotive housings, PC sheets.

• Film & Flexible Packaging: LDPE agricultural film, LLDPE stretch wrap, PP woven bags, multi-layer laminated scrap. Wet crushing recommended to prevent rotor wrapping.

• Bulk Volume Reduction: Mixed rigid plastics from municipal waste collection, oversized purgings from compounding extruders, and off-spec pallets.
