Plastic Crusher Machine: Industrial-Grade Recycling Solution

Plastic crusher machines (also known as industrial shredders or granulators) are specialized recycling equipment designed for size reduction of plastic materials. These robust machines process various plastic forms – including pipes, profiles, containers, films, and rubber products – into uniform granules for reuse in production lines. As essential equipment in circular economy systems, they enable manufacturers to recycle up to 90% of production scrap like sprues, rejected parts, and post-consumer waste. Modern units handle 100-2,000 kg/hour of materials, with motor power ranging from 3.5kW to 150kW depending on application requirements.

Engineering Features of

plastic crusher machine

Our plastic crushers incorporate cutting-edge industrial design principles:

1. Precision Cutting Systems

Configurable blade types (claw, flat, or sheet knives) fabricated from SKD-11/D2 alloy steel with 4-edge rotatable design. V-angled mounting ensures uniform material engagement and 300% longer edge life versus standard blades.

2. Intelligent Drive Technology

Gear-reduced motors (150-500 RPM) deliver high-torque crushing while reducing energy consumption by 25% compared to high-speed units. Automatic reversal prevents jamming during overloads.

3. Advanced Material Flow

Customizable feed openings (tube-shaped for pipes, rectangular for sheets) with hydraulic feeding options. Sound-damped hoppers (75 dB operational noise) enable workshop-friendly operation.

4. Smart Control Integration

PLC systems with temperature monitoring and auto-shutdown protection. Optional water-cooling jackets prevent material melting during extended runs.

Benefits of Kaifeng plastic crusher machine

Implementing our crushers delivers measurable production advantages:

1. Cost Reduction

Immediate in-house recycling (≤30 seconds) prevents material degradation from oxidation/moisture absorption. Minimizes virgin material purchases by 40-60%.

2. Quality Preservation

Rapid processing maintains polymer integrity and color consistency in regrind material — critical for high-tolerance injection molding.

3. Space Optimization

Compact modular designs with wheeled bases enable placement beside injection machines. Quick-clean mechanisms allow material/color changeovers in ≤15 minutes.

4. Safety Compliance

Interlocked safety switches cut power during maintenance access. CE-certified electrical systems with overload protection.

Industry Applications

Versatile processing capabilities cover diverse material types and forms:

1. Hard Plastics Recycling

ABS/PP/PC sheets, engineering resin runners, thick-walled containers (up to 50mm thickness) using claw blade configurations.

2. Soft Material Granulation

Specialized low-RPM (≤300) units with water cooling prevent melting of TPE, TPU, or EVA materials.

3. Large Volume Processing

Single-shaft shredders with hydraulic rams process pallets, barrels, and automotive bumpers.

5. Specialized Recovery

Pipe/Tubing: Guided feed channels for PE/PVC pipes ≤Φ250mm

Film/Fiber: Anti-wrapping rotors for agricultural film & woven bags

Electronic Waste: Dedusting systems for CRT housings and printer parts

FAQ

Q1: Why does soft plastic melt/stick during crushing?

Soft polymers (TPE/TPU) become adhesive above 50°C. Our plastic crusher’s specialized units maintain temperatures below 40°C via water-cooled chambers and optimized blade geometry.

Q2: Can one plastic crusher machine handle both soft and hard plastics?

Standard plastic crushers compromise performance. We recommend:

Hard plastics: High-torque (400-500 RPM) units with claw blades

Soft/fibrous: Low-speed (150-300 RPM) crushers with flat blades and cooling

Q3: What maintenance ensures the longevity of the plastic crusher machine?

Critical routines include:

• Blade gap adjustment (0.5-0.8mm based on motor power)
• Bearing lubrication (food-grade grease quarterly)
• Screen inspection (replace at 30% wear)
• V-belt tension checks

Q4: Can your plastic crusher machine be linked with the existing injection molding production line to achieve automated recycling?

Yes, Kaifeng’s plastic crushing equipment supports three integration solutions:

• Basic version: the crusher outlet is connected to the injection molding machine hopper (pneumatic conveying distance ≤ 15 meters)
• Smart version: PLC system synchronous control (waste → crushing → back-mixing ratio adjustment)
• Whole factory solution: central recycling system + multi-machine joint control
