Introduction of Rotary Drum Cooling Machine

Our rotary drum cooling machine is regularly used to cool fertilizers with a certain temperature and granularity in compound fertilizer production lines. The inlet temperature of materials generally is 60 °~ 80°, the outlet temperature is less than 40°. It is always used in combination with the drying machine to greatly increase cooling speed, improve the cooling rate and product quality, and further remove the water and reduce fertilizer particle temperature.
Features of Rotary Drum Cooling Machine
1. With specially reasonable design of lifting flights to maximize heat transfer between the material and cooling air.
2. The cooling air passes through the rotary drum body with small resistance, low energy consumption.
3. Wide application range, our rotary cooling machine has a strong adaptability of materials and can be used to cool various materials.
4. Compact structure, easy to clean and maintain, high cooling efficiency, stable and reliable performance, and high adaptability, high production capacity, and long service life.
Application of Rotary Drum Cooling Machine
Rotary drum cooling machine is regularly used for cooling fine chemical materials in compound fertilizer production lines, building material production, metallurgic and chemical industries, cement production lines, etc. It is applicable for cooling the following materials:

Rotary Cooling Machine

→ Fertilizers (potash, DAP, MAP, NPK, TSP)
→ Minerals and Ores (Copper, Iron, etc.)
→ Limestone and Lime
→ Sand and Gravel
→ Industrial Waste and Sludges
→ Municipal Waste
Working Principle of Fertilizer Rotary Drum Cooling Machine

As a kind of heating exchange equipment, fertilizer rotary cooling machine is utilized cool gas to cool hot materials. Meanwhile, cooling equipment is able to make full use of the exhaust heat, thus improving the thermal efficiency of a kiln. It is composed by the evaporator, condenser, compressor, an expansion valve, fan and the housing. When it is normally working, the evaporator absorbs heat from the outside world and condenser emit heat outwardly, under the action of fan, moist air enters from the left air inlet and takes heat exchange through the evaporator, and then its temperature decreases; when the humid air reaches the dew point temperature, moisture is precipitated due to condensation, the absolute moisture content of the humid air declines, while its temperature would raise when through the condenser for heat exchanging again, so as to achieve the purpose of insulation and dehumidification.
