A complete fertilizer production line includes feeding system, crusher, mixer, granulator, cooling dryer and packing machine. Among them, the cooling machine can quickly cool high-temperature materials and store them for a longer period of time. The rotary cooler is suitable for powdery or granular materials. While heating at high temperature, it avoids the spontaneous combustion and self-explosion of materials during drying. It can be used in conjunction with a dryer to increase production capacity and efficiency.
Advantage：
1. While cooling the clinker, the heat energy carried by the high-temperature material can be absorbed by the air, thereby reducing heat consumption
2. The cooled air can be used as secondary circulating air, and the thermal efficiency can reach 95%
