What are the key operating points for a rotary drum granulator?

A rotary drum granulator is core equipment for large-scale compound fertilizer production, and its operating status directly impacts pellet quality and production efficiency. Understanding key operating precautions can reduce malfunctions, increase production capacity, and provide continuous operation for compound fertilizer production line s. Raw material ratio and moisture control are essential. Materials entering the drum must be precisely mixed according to the recipe to ensure a stable ratio of nitrogen, phosphorus, potassium, and other components, avoiding nutrient imbalance in the pellets due to uneven raw materials. Moisture content must also be strictly controlled. Excessive moisture content can easily cause the material to stick to the wall and clump, while excessive moisture content can lead to low pellet formation efficiency. This requires real-time adjustment through online monitoring. Operating parameters must be precisely adjusted. Before starting the machine, calibrate...
