Cooling and drying is a good way to reduce fertilizer granules moisture and temperature, and it’s suitable for wet fertilizer producing plant.
If you choose rotating npk fertilizer granulating machine, after granulating, the fertilizer pellets will be fed into rotary drying machine. Inner the machine, there are many lifting boards. When drying granules, the drum rotating at a even speed. Inner if, the lifting boards can lift the fertilizer pellets continuously. Then the granules falling and rolling with gravity. During this process, fertilizer granules can get full contact with hot air, the water also evaporates very well. After that, the fertilizer conveyor can transport the granules into fertilizer cooling equipment. With strong cold air, the high temperature pellets can be cooled easily.
