Industrial Plastic Crushers: Model 800 Guide to Capacity and Applications

In the realm of plastic recycling and waste management, the Model 800 industrial plastic crusher stands as a versatile and high-performance solution designed to handle medium to large-scale plastic waste processing. Characterized by its robust construction, efficient size reduction capabilities, and adaptability to diverse plastic materials, this machine has become a cornerstone in recycling facilities, manufacturing plants, and waste management operations worldwide.

With a processing capacity ranging from 500 kg/h to 1,000 kg/h and motor power typically between 22 kW and 55 kW, Model 800 crushers are engineered to break down various plastic types—including PET bottles, HDPE pipes, PVC panels, and plastic lumps—into uniform flakes or granules. This guide explores the technical specifications, working principles, applications, and key considerations for selecting and operating Model 800 plastic crushers.

Technical Specifications of Model 800 Crushers

Model 800 plastic crushers are defined by their balance of power, throughput, and precision. Below is a detailed overview of their core specifications, drawing from industry-leading manufacturers like WEIMA, Genox, and Bogda:

Working Principle

Model 800 crushers operate on a single-shaft or double-shaft design, depending on the application:

• Single-Shaft Crushers (e.g., WEIMA WLK 800): Equipped with a rotating shaft fitted with 4-way indexable blades. A hydraulic pusher feeds materials into the cutting chamber, where blades shear and tear plastic against fixed counter-knives. The shredded material passes through a screen to ensure uniform particle size. Ideal for rigid plastics like pipes and lumps.

• Double-Shaft Crushers (e.g., SPRD-800): Feature two intermeshing shafts with claw blades that “chew” through materials. Suitable for flexible plastics (films, bags) and mixed waste, offering higher torque for tough applications.

Both designs leverage high-speed rotation (600–1,200 RPM) and precision blade geometry to minimize energy consumption while maximizing throughput.

Key Applications

Model 800 crushers are versatile across industries, with proven performance in:

1. Plastic Recycling Facilities

• PET Bottle Recycling: Crushes post-consumer PET bottles into 12–18 mm flakes for washing and pelletizing.
• HDPE Pipe Processing: Reduces large-diameter HDPE pipes (up to 315 mm) into regrind for reuse in pipe extrusion.

2. Manufacturing Waste Management

• Injection Molding Scrap: Processes purge lumps, runners, and defective parts into regrind for direct reuse in production.
• Thermoforming Waste: Integrated with thermoforming machines (e.g., Wayne WN-800) to crush trim scrap into 3–8 mm particles for immediate recycling.

3. Industrial Plastic Processing

• PVC Profile Crushing: Handles PVC foam boards, window frames, and profiles with minimal dust generation (e.g., Bogda SWP 800).
• Film and Woven Bag Recycling: Equipped with anti-wrap blades to process LDPE/PP films and woven bags into uniform flakes.

Advantages of Model 800 Crushers

1. High Efficiency

• Energy-Saving Motors: IE3 premium efficiency motors reduce power consumption by 15–20% compared to standard motors.
• Continuous Operation: Hydraulic pushers and automatic feeding systems enable 24/7 operation with minimal downtime.

2. Durability

• Wear-Resistant Components: Blades made from SKD-11 steel (62–64 HRC hardness) withstand abrasion from glass-filled plastics.
• Sealed Bearings: Outboard bearing housings prevent dust and moisture ingress, extending service life.

3. Safety and Compliance

• CE Certification: Meets EU safety standards (e.g., EN 12012-1) with emergency stop buttons and interlocked access doors.
• Low Noise: Soundproofed chambers reduce operating noise to <85 dB, compliant with workplace regulations.

Market Trends and Future Outlook

The global plastic crusher market is projected to grow at a CAGR of 6.3% through 2035, driven by:

• Stringent Waste Regulations: EU’s Single-Use Plastics Directive and China’s plastic waste import bans boost demand for domestic recycling equipment.
• Automation Integration: IoT-enabled models (e.g., WEIMA WLK 800 with Siemens PLC) offer remote monitoring and predictive maintenance.
• Sustainability Goals: Manufacturers prioritize energy-efficient crushers to reduce carbon footprints, with Model 800 variants leading in eco-friendly design.

Conclusion

Model 800 industrial plastic crushers represent a balance of power, versatility, and reliability, making them indispensable for modern plastic recycling and waste management. Whether processing post-consumer bottles, industrial scrap, or flexible films, these machines deliver consistent performance, high throughput, and compliance with global safety standards. As the industry evolves, Model 800 crushers will continue to play a pivotal role in advancing circular economy goals by transforming plastic waste into valuable resources.

For businesses seeking to optimize their recycling operations, investing in a Model 800 crusher—backed by reputable manufacturers like WEIMA, Genox, or Bogda—ensures long-term efficiency and sustainability.
