At the end of fertilizer production lines, the drum fertilizer cooler acts like a professional “temperature regulator”, rapidly cooling high-temperature fertilizer granules to suitable temperatures. This equipment, similar in shape but complementary in function to rotary drum dryers, has become an indispensable component in modern fertilizer production lines with its efficient cooling capacity and stable performance.
1. Counter-Current Cooling: The Secret to Efficient Temperature Reduction
The rotary drum cooler adopts an innovative counter-current air flow design. Materials enter from the feed inlet while cold air is introduced from the discharge end, moving in opposite directions to maximize heat exchange. This design not only improves cooling efficiency by over 40% but also further removes residual moisture from granule surfaces, making the finished fertilizer products drier and more stable.
Eco-Friendly Design
Closed structure effectively reduces cold air pollution and improves workshop environment
Intelligent Matching
Perfect coordination with dryers increases cooling rate by 50% and reduces labor intensity by 60%
Wide Applicability
Besides fertilizers, it can also cool various powdered and granular materials
2. Technical Specifications: Precisely Meeting Production Needs
| Model | Capacity(t/h) | Main Motor Power(kW) | Reducer Model | Weight(tons) |
| LQ10100 | 1-3 | 5.5 | ZQ250 | 3.8 |
| LQ12120 | 3-5 | 7.5 | ZQ350 | 5.7 |
| LQ15150 | 5-7 | 15 | ZQ400 | 9.7 |
As shown in technical specifications, the rotary drum cooler series covers different capacity needs from 1-7 t/h, using standard ZQ series reducers with stable speed ratio of 23.34 to ensure smooth and reliable operation.
3. Core Advantages: Multiple Values Beyond Cooling
The rotary drum cooler brings more than just temperature reduction to fertilizer production lines:
- Quality Improvement: Prevents caking caused by high temperatures and maintains granule integrity
- Energy Saving: Heat recovery system can reuse some waste heat to reduce energy consumption
- Space Optimization: Compact structure design reduces floor space by 30% compared to traditional cooling equipment
- Strong Adaptability: Can handle various fertilizers including organic and compound fertilizers with different particle sizes
From efficient cooling to eco-friendly design, from stable operation to energy saving, the rotary drum cooler is helping fertilizer producers improve product quality, reduce production costs and enhance market competitiveness with its comprehensive advantages.
