Product Overview

The Xushi Heavy Duty Waste Plastic Crusher Machine is engineered for high-capacity, size-reduction processing of various plastic wastes. It serves as a critical pre-treatment solution, transforming bulky plastic waste into uniform flakes or regrinds, perfectly prepared for downstream washing, drying, and pelletizing lines.

This industrial-grade granulator is optimized to process a wide range of materials, including rigid PP/PE containers, heavy-wall PVC/PE pipes, injection molding sprues, plastic profiles, films, and bulky industrial purging lumps.

Key Features

Heavy-Duty Reinforced Structure
The machine frame is constructed from heavy-gauge carbon steel with a reinforced box weldment design. This robust engineering minimizes structural vibration, absorbs high-impact loads during heavy purging crushing, and ensures stable, 24/7 continuous industrial operation.

High-Efficiency V-Cut Rotor & Blades
Featuring an optimized V-shape scissor-cut rotor configuration. The rotating blades angle inward toward the center, concentrating the cutting force, which reduces power consumption by 15%–20%, minimizes dust generation, and prevents materials from wrapping around the shaft.

Premium D2/SKD-11 Blade System
Equipped with high-quality D2 (Cr12MoV) or SKD-11 wear-resistant alloy steel blades. Vacuum heat-treated to HRC 58-62, these blades offer superior wear resistance and impact toughness. Designed with adjustable structures, the blades can be reground multiple times to maximize service life and lower operating costs.

Customizable Output Control
Heavy-duty, easily replaceable screens with various hole geometries and sizes (from 8 mm to 50 mm) allow processors to tailor the output flake size to the exact requirements of their downstream recycling equipment.

Operator-Friendly Maintenance
Features an assisted upper-chamber opening system (hydraulic or mechanical) that provides quick, safe, and open access to the cutting chamber for blade replacement, screen cleaning, and rapid material changeovers.

Applications & Material Capability

The Heavy Duty Crusher is highly versatile and capable of handling:
Flexible Plastics: PP woven bags, PE plastic films, agricultural films, non-woven fabrics.

Rigid Plastics: PET bottles, HDPE milk jugs, PVC pipes, ABS/PC electronic housings.

Industrial Scrap: Injection molding runners and sprues, extrusion scrap, start-up purgings, and thick-walled profiles.

Materials We Process

Material	Typical Form / Application	Rotor Blade Type Suggestion
PP	Woven bags, jumbo bags, thin-walled containers, crates	V-Cut Blades (Prevents wrapping)
PE	Agricultural films, stretch wraps, HDPE bottles, gas pipes	Claw Blades / Flat Blades
PVC	Rigid water pipes, window profiles, cable trunking, soft PVC	Heavy-Duty Staggered/Claw Blades (For high hardness)
PET	Beverage bottles, food packaging thermoforming trays	Optimized Chevron Blades (Reduces dust)
Other Plastics	ABS, PC, Nylon, engineering plastic lumps, purgings	Custom Heavy Rotor (Solid design, high impact resistance)

Working Principle

Feeding: Bulk waste plastics enter the heavy-duty cutting chamber via the gravity hopper (optimized for conveyor or manual feeding).

Shearing: Inside the chamber, the high-speed rotating blades mesh with the strategically positioned stationary (counter) blades, generating powerful dual-shear cutting forces.

Sizing: Material is continuously sheared until it is small enough to pass through the screen openings. Particles larger than the mesh are swept back up for another cutting cycle.

Main Components

Feeding Hopper: Sound-insulated, anti-splash design to prevent material fly-back.

Crushing Chamber: Fully welded, thick-walled steel plate chamber with wear-resistant liners.

Heavy Duty Rotor: High-mass steel rotor designed to store rotational inertia for handling thick plastics.

Alloy Blades: Premium D2/SKD-11 wear-resistant rotary and stationary knives.

Screen Cradle: Robust screen support, available with hydraulic lowering for easy maintenance.

Power & Drive: Standard high-efficiency SIEMENS or equivalent brand motors, driven by heavy-duty V-belts.

Why Choose Xushi Plastic Crusher

Application-Specific Customization: We do not believe in "one-size-fits-all." We customize the rotor speed, blade geometry (claw, flat, chevron), and hopper feed method based on your material's physical properties.

Industrial Durability: YUSHI machines feature oversized bearings installed outside the cutting chamber to prevent dust and water ingress, significantly extending bearing lifespan.

Turnkey Recycling Solutions: We manufacture complete washing and pelletizing lines. Our crushers integrate seamlessly with our belt conveyors, metal detectors, cyclone discharge systems, and bagging stations.

Quality Inspection & Safety Standard

CE & ISO Compliant: All equipment is built to meet international CE safety directives and ISO9001 quality standards.

Pre-Shipment Trial Test: We conduct rigorous dry-running and wet-testing with target materials at our facility before shipping. We provide detailed HD test videos or support live-streamed FAT (Factory Acceptance Test) for global buyers.

Safety Interlocks: Equipped with emergency stop buttons, limit switches, and safety interlocks on the chamber and screen to prevent motor start-ups during maintenance.

After-Sales & Engineering Support

24/7 Technical Response: Experienced mechanical and electrical engineers are online to assist with installation, commissioning, and optimization questions.

Rapid Spare Parts Supply: Critical wearing components (blades, screens, belts) are kept in stock and can be dispatched worldwide via air express within 48 hours.

Lifetime Consulting: We provide upgrade recommendations and blade regrinding guidelines throughout the machine's life cycle.

FAQ

Q: What material options do you offer for the crusher blades?

A: Our standard blades are made of high-quality D2 (Cr12MoV) alloy steel, which offers an excellent balance of wear resistance and toughness. For high-abrasive plastics (e.g., plastics with glass fiber or sand), we recommend premium SKD-11 or customized tungsten carbide tipped blades to extend the interval between sharpenings.

Q: How can we prevent the crusher from overheating when processing thin films or heat-sensitive materials?

A: For heat-sensitive plastics or thin films, we can equip the crusher with a Water-Cooling System (jacketed cooling on the bearing houses and chamber) or configure it as a Wet Crusher (water-sprayed crushing), which cools the plastic, reduces dust, and pre-washes the materials during processing.

Q: Can I run a test with my own specific plastic waste before placing an order?

A: Absolutely. We welcome buyers to send material samples to our testing facility. We will run a complete test-grind, record high-definition video of the process, measure the output size, and send the crushed flakes back to you for evaluation.

Q: How often do the blades need to be reground?

A: This depends on the material type and contamination level (such as sand or metal). For clean rigid PP/PE, blades typically run for 80–120 hours before requiring regrinding. Our adjustable blade design allows each blade set to be reground 5 to 8 times, depending on the wear depth.

Q: Is the crusher suitable for inline integration with downstream washing lines?

A: Yes, our heavy-duty crushers are designed for seamless integration. We regularly customize discharge hoppers to connect with blower extraction systems, screw conveyors, or washing line pre-treatment systems for fully automated processing.
