Double shaft plastic shredder is a powerful universal crushing equipment that uses two relatively rotating shafts to perform cutting, tearing, and crushing processing on materials. Due to its sturdy structure, large torque, and wide application range, double shaft shredders have become one of the core equipment in the waste recycling field. This article will provide a detailed introduction to the application scenarios and value of double shaft plastic shredders in various industries.
Double Shaft Shredder Overview
The double shaft plastic shredder adopts a double shaft low-speed high-torque design, with two blade shafts rotating in opposite directions and blades arranged in a spiral pattern. When material enters the crushing chamber, it is first gripped by the blade tips, then torn, sheared, and crushed by the cooperation of the two blade shafts.
The main features of double shaft shredders include:
- High capacity: Processing capacity of 100-1000kg/h, meeting large-scale production needs
- High crushing efficiency: Double shaft shearing design, high crushing efficiency
- Multi-material adaptation: Can process plastics, rubber, wood, metals, and other materials
- Replaceable blades: Blades can be replaced, reducing maintenance costs
- Conveyor belt available: Can be equipped with conveyor belts for automated feeding
Cable Recycling Industry Applications
In the cable recycling industry, double shaft plastic shredders are mainly used in the pre-treatment stage of waste cables. The outer sheath of cables is usually made of PVC, PE and other plastic materials, which need to be crushed before subsequent copper-plastic separation.
Application process: Waste cables → Double shaft shredder crushing → Granular materials → Copper granulator/Electrostatic separator → Copper granules + Plastic granules
Double shaft shredders can crush cables into appropriately sized particles for fine sorting by subsequent copper granulators. For thicker cables, it is recommended to choose PC600 or PC1000 models with capacity reaching 500-1000kg/h.
Tire Processing Industry Applications
Waste tires are important solid waste resources containing large amounts of recyclable rubber and steel wire. Double shaft plastic shredders play a key role in tire recycling processing lines.
For tire shredding processing, dedicated tire shredding machines are available, featuring double shaft low-speed high-torque design, specifically optimized for the tough characteristics of tires. If processing volume is large or other materials need to be handled, double shaft plastic shredders can be chosen.
Application scenarios:
- Tire pyrolysis: Shredding tires into appropriate sizes as pyrolysis raw materials
- Rubber granule production: Producing rubber granules for waterproof materials, sports facilities, etc.
- Steel wire recovery: Separating steel wire through magnetic separation after shredding
Wood Processing Industry Applications
Wood processing plants generate large amounts of waste materials such as edge scraps, sawdust, and waste wooden pallets during production. Double shaft plastic shredders can effectively process these wood wastes, crushing them into wood chips or flakes for biomass fuel or engineered panel production.
Application advantages:
- Processing wooden pallets, plywood, and other hard woods
- Adjustable discharge particle size to meet different usage needs
- Supporting conveyor systems for automated production
- Low noise design, meeting environmental requirements
Plastic Recycling Industry Applications
Plastic recycling is an important part of circular economy. Double shaft plastic shredders are widely used in the plastic recycling industry and can process various types of plastic waste.
Types of plastics that can be processed:
- General plastics: PE, PP, PVC, PS, etc.
- Engineering plastics: ABS, PC, PA, etc.
- Plastic products: Plastic pallets, plastic drums, plastic films, etc.
- Industrial waste: Injection molding runner materials, blow molding edge materials, etc.
Crushed plastic granules can be processed through cleaning and granulation to produce recycled plastic pellets, achieving resource recycling.
Industrial Solid Waste Processing Industry
Industrial production generates various solid wastes such as textile waste, leather scraps, and packaging materials. Double shaft plastic shredders can effectively process these industrial solid wastes, achieving reduction and resource utilization.
Typical applications:
- Textile recycling: Crushing processing of waste clothing and textile scraps
- Leather processing: Crushing of leather scraps for subsequent reuse
- Packaging materials: Processing of paper-plastic composite packaging and foam plastics
Rekomendasi Pemilihan Peralatan
According to different industry application scenarios, it is recommended to choose appropriate double shaft shredder models:
| Model | Daya (kW) | Kapasitas (kg/jam) | Applicable Scenarios |
|---|---|---|---|
| PC260 | 15-22 | 100-300 | Small-scale recycling stations, laboratories |
| PC400 | 30-45 | 300-500 | Medium plastic recycling plants |
| PC600 | 55-75 | 500-800 | Large recycling enterprises, industrial production |
| PC1000 | 90-110 | 800-1000 | Large-scale processing centers |
The following factors need to be considered when selecting equipment:
- Material characteristics: Hardness, toughness, moisture content, etc.
- Kebutuhan kapasitas: Hourly processing volume requirements
- Discharge particle size: Requirements for particle size in subsequent processes
- Kondisi lokasi: Equipment footprint, power configuration
Maintenance Points
To ensure normal operation and extend service life of double shaft shredders, pay attention to the following maintenance points:
- Regular blade inspection: Replace blades timely when worn to maintain crushing efficiency
- Lubrication maintenance: Regularly add lubricating oil to reducer, bearings, and other parts
- Cleaning maintenance: Clear residual materials in crushing chamber to prevent accumulation
- Fastening inspection: Regularly check if bolts in various parts are loose
- Motor protection: Avoid overload operation, pay attention to motor temperature rise
