With the general trend of reducing costs and increasing efficiency in industrial production, energy-saving optimization of drum fertilizer coolers has become a key focus for many companies. In fact, without major equipment modifications, adjusting operating parameters and optimizing system configuration can effectively reduce energy consumption and operating costs.
First, optimize cooling medium recycling. A circulation device can be added to the cooling system. For example, warm water discharged from the jacket can be directed to a cooling tower for cooling and then recirculated back to the jacket for reuse, reducing fresh water usage. For forced air cooling, the warm exhaust air can be cooled through a heat exchanger before being re-circulated into the drum as cooling air, reducing fan energy consumption.
Second, adjust drum fertilizer cooler operating parameters to suit production needs. Parameters can be dynamically adjusted based on the material’s real-time temperature and processing volume. For example, if the material feed temperature is lower than expected, the drum fertilizer cooler speed can be appropriately reduced to extend the material’s residence time and reduce the cooling medium flow rate to avoid overcooling. When processing volume decreases, the drive motor speed can be reduced to reduce motor energy consumption.
Third, add insulation to reduce heat loss. If the drum shell is exposed to air for extended periods, it will dissipate heat into the surrounding environment, increasing the load on the cooling system and causing energy loss. Installing an insulation layer (such as rock wool or aluminum silicate fiber) between the drum shell and the jacket can reduce heat radiation from the shell. Also, insulate the pipes at the feed and discharge ports to prevent the material from absorbing ambient heat during transportation, which would increase the cooling load.
