In modern fertilizer production, belt conveyors play the role of "industrial blood vessels," with their importance mainly reflected in three aspects:
1. Continuous production guarantee: Achieves seamless connection from raw materials to finished products, maintaining 24/7 uninterrupted production
2. Key to process optimization: Connects critical processes such as crushing, mixing, granulation, drying, cooling, and packaging
3. Core of cost control: Compared to manual handling, can reduce transportation costs by 30-50% [1]

Dusty raw material conveying |
Five key factors to consider when selecting belt conveyors:
· Material characteristics: Including particle size (0-10mm powder or 10-50mm granules), moisture content (≤15% preferred), corrosiveness, etc.
· Process parameters: Conveying capacity (typically 20-100t/h), conveying distance (commonly 50-200m), lifting height
· Environmental conditions: Indoor/outdoor, temperature (-20℃ to +50℃), humidity, corrosive gases
· Special requirements: Explosion-proof, dust-proof, heat-resistant, anti-stick, etc.
· Economic indicators: Equipment investment, energy consumption (about 0.5-2kW·h/t), maintenance costs
For example, a 100,000-ton annual capacity compound fertilizer production line typically requires:
· Raw material section: 800-1000mm width trough belt conveyor
· Granulation section: Heat-resistant belt conveyor (80-120℃)
· Finished product section: Anti-static belt conveyor (prevents fertilizer granule adhesion)
Belt conveyor applications have extended far beyond the fertilizer industry, including:
