Reducing the energy consumption of the rotary drum granulator can be started from the following aspects:

1. Optimize the process parameters and control the material humidity: minimize the addition of water during granulation, moderately improve the temperature and solubility of the material, so as to reduce thermal energy consumption, improve the ball passing rate, increase output and reduce production costs. Set the speed of the drum reasonably to avoid energy waste caused by too high or too low speed.

2. Adopt energy-saving technology: Install frequency conversion speed regulating device, so that the speed adjustment accuracy is improved, the particle pass rate is improved, thus reducing energy consumption. The multi-stage atomizing nozzle and Angle adjusting device are used to improve the liquid distribution uniformity and improve the liquid utilization rate. Set up three temperature control areas to achieve dynamic balance and avoid unnecessary energy consumption.

3. Equipment transformation and upgrading: The use of acid granulation process to transform the drum steam granulation compound fertilizer device for energy saving technology can reduce energy consumption and improve product quality.

4. Improve equipment operation efficiency: By optimizing the structure and process of organic fertilizer equipment, reduce the production of return material, improve the rate of one-time pellet formation, and reduce energy consumption. Check and maintain the equipment regularly to ensure that the equipment is in optimal operating condition and reduce the energy consumption caused by equipment failures.

5. Intelligent and automatic control: Install online particle size analyzer and humidity sensor, collect particle size distribution, moisture content and other data every 15 minutes, and automatically adjust the parameter combination through PLC system.

Through the above measures, the energy consumption of the drum granulator can be effectively reduced, the production efficiency can be improved, and the environmental impact can be reduced.
