I. Traditional Conveyor Equipment Types and Characteristics
1. Belt Conveyor
- The most common type, constructed with rubber or metal belts, suitable for horizontal or inclined transport.
- Advantages: High conveying capacity (up to 5,000 tons/hour) and long distances (up to 15 kilometers for a single conveyor).
- Disadvantages: Large footprint, unsuitable for hot or corrosive materials.
- Typical applications: Bulk cargo transportation in mines and ports.
2. Screw Conveyor
- Uses spiral blades to propel material, suitable for powdered or granular materials.
- Advantages: Good sealing, preventing dust leakage.
- Disadvantages: High energy consumption, short conveying distances (generally no more than 30 meters).
- Reference: According to the Mechanical Engineering Handbook, conveying efficiency is approximately 60%-80%.
3. Chain Conveyor
- Uses a chain to pull a carrier (such as a pallet or hopper) for transport, suitable for heavy materials.
- Advantages: Strong load-bearing capacity (single-point load capacity up to 5 tons), high-temperature resistance.
- Disadvantages: Noisy, high maintenance costs.
II. Emerging Conveying Technologies and Trends
1. Pneumatic Conveying Systems
- Powdered materials are conveyed using airflow, in both dilute and dense phases.
- Advantages: No mechanical contact, suitable for the food and pharmaceutical industries.
- Case study: Conveying speeds in milk powder production lines can reach 20 m/s (data source: American Pneumatic Conveying Association).
2. Intelligent Conveying Equipment
- Integrates the Internet of Things (IoT) and AI technologies to achieve automated sorting and real-time monitoring.
- For example: JD Logistics' AGV sorting system has an error rate of less than 0.01%.
