800 Plastic Crusher: Function, Application, and Selection Guide

Introduction
The 800型塑料破碎机 (Type 800 Plastic Crusher) is a mid-to-large-scale industrial machine designed to shred plastic waste into reusable particles. Widely used in recycling facilities, manufacturing plants, and waste management operations, this equipment plays a pivotal role in reducing plastic pollution and promoting circular economies. This article explores the features, applications, and considerations for selecting a Type 800 plastic crusher.

What Is a Type 800 Plastic Crusher?

The “800型” designation refers to the machine’s feed port dimensions (typically 800mm in width), indicating its capacity to process bulk materials. These crushers are engineered for:

• High Throughput: Capable of shredding 500–2,000 kg of plastic waste per hour.
• Versatility: Suitable for rigid plastics (e.g., buckets, pipes), films, and post-consumer waste.
• Durability: Built with reinforced steel frames and hardened blades for long-term use.

Key Features of Type 800 Crushers

1. Cutting System
   • Dual-Shaft Design: Two counter-rotating blades ensure efficient grinding and minimal jamming.
   • Blade Material: High-quality alloy steel or tungsten carbide blades resist wear and corrosion.
2. Motor and Power
   • Electric Motors: Ranging from 30kW to 75kW, depending on the model and application.
   • Energy Efficiency: Modern models incorporate variable frequency drives (VFDs) to reduce power consumption.
3. Safety and Compliance
   • Overload Protection: Automatically shuts down the machine to prevent motor damage.
   • Noise Reduction: Enclosed chambers and vibration-damping materials minimize workplace noise.
4. Screening Mechanism
   • Adjustable Screens: Control the size of output particles (e.g., 10mm–50mm flakes).
   • Quick-Release Systems: Simplify screen replacement for different output requirements.

Common Applications

1. Recycling Plants: Process post-industrial and post-consumer plastic waste into raw materials for new products.
2. Manufacturing Facilities: Shred production scrap (e.g., injection molding rejects) for in-house reuse.
3. Municipal Waste Management: Handle plastic waste from households and commercial zones.
4. Textile Industry: Recycle PET bottles into fibers for clothing and carpets.

How to Choose a Type 800 Plastic Crusher

1. Material Compatibility
   • Soft Plastics: Films, bags, or foam require blades with a specific tooth profile.
   • Hard Plastics: Thick-walled containers or pipes need robust blades and powerful motors.
2. Output Requirements
   • Particle Size: Smaller flakes require finer screens and slower blade speeds.
   • Throughput: Match the machine’s hourly capacity to your waste volume.
3. Space and Infrastructure
   • Footprint: Ensure the machine fits your facility’s layout.
   • Power Supply: Confirm compatibility with local electrical standards (e.g., 380V/50Hz).
4. Budget and Total Cost of Ownership
   • Upfront Cost: Type 800 crushers typically range from $15,000to$80,000, depending on features.
   • Operating Costs: Factor in energy use, blade replacements, and maintenance.

Maintenance Tips for Longevity

• Daily Cleaning: Remove plastic residues to prevent jamming and blade dulling.
• Blade Sharpening: Use a specialized sharpening tool every 3–6 months.
• Lubrication: Apply high-temperature grease to bearings and gears monthly.
• Inspection: Check for worn blades, loose bolts, or motor vibrations weekly.

Case Study: Type 800 Crusher in Action

A packaging manufacturer in Guangdong, China, installed a Type 800 crusher to process 1,200 kg/day of PP scrap. By integrating the machine into their production line, they reduced raw material costs by 25% and achieved a 18-month ROI. The crusher’s dual-shaft design and VFD motor ensured consistent performance despite fluctuating waste volumes.

Innovations in Type 800 Crusher Technology

1. Smart Controls: IoT-enabled systems monitor blade wear, motor temperature, and output quality in real time.
2. Modular Design: Machines can be upgraded with additional screens, motors, or safety features.
3. Eco-Friendly Upgrades: Solar-compatible models and hybrid (electric/diesel) power systems for off-grid use.

Common Challenges and Solutions

• Material Jamming: Install a pre-shredder or reduce feed speed.
• Uneven Output: Adjust screen size or blade clearance.
• Excessive Noise: Add soundproofing panels or upgrade to a fully enclosed model.

Future Trends

As sustainability becomes a global priority, Type 800 crushers are evolving to:

• Automate Waste Sorting: Integrate AI-driven sensors to separate plastics by type.
• Support Circular Economies: Partner with recyclers to create closed-loop material systems.
• Reduce Carbon Footprints: Use recycled steel in machine construction and biodegradable lubricants.

Conclusion

The Type 800 plastic crusher is a robust, versatile solution for businesses seeking to reduce plastic waste and lower material costs. By evaluating your operational needs, budget, and maintenance capabilities, you can select a machine that delivers long-term value. Investing in quality equipment and staying informed about technological advancements ensures your operation remains efficient and sustainable.
