Why is the Rotary Dryer the Core Energy Consumer in an NPK Production Line?
Q: Why is the rotary dryer generally considered a major energy consumer in an NPK compound fertilizer production line? A: This assessment is supported by ample data. In a complete NPK compound fertilizer production line, the energy consumed in the drying process typically accounts for more than 60% of the total energy consumption. This means that controlling the dryer's energy consumption is equivalent to grasping the "key" to energy conservation and consumption reduction for the entire production line. The high energy consumption of the rotary dryer stems from multiple contradictions between its working principle and the characteristics of compound fertilizer materials.
