In the process of compound fertilizer production line, the material must be dried and cooled. At this point, a dryer, cooler and screening machine are required. Many customers are not familiar with chemical fertilizer processing technology. Here is how to dry and cool the materials in the fertilizer production line.
The particles to be dried processed by NPK fertilizer granulator are transported to the feed port of the feeder through the belt conveyor, and the granular materials flow into the drying cylinder along the feed trough. The feeder is mounted outside the drying cylinder.
Driven by the deceleration drive system, the granular material moves backward with the rotation of the drying cylinder, and the heated hot air is blown into the feed end. It directly contacts the material of the drying cylinder, evaporates its water vapor and dries it.
In the drying process, according to the drying degree of the material, the deceleration drive system can adjust the speed through the frequency converter.
Dry and cold particles in compound fertilizer production line
The intermediate sensing draft hood draws steam from the drying cylinder. Then, as the drying material rotates, it enters the cooler again. Under the action of the middle induction draft hood, the natural wind enters the cooler from the unclosed end.
As the cooler rotates, the material is picked up and the material temperature is directly reduced to the natural temperature. After that, the granular material will enter the drum screen, and the unqualified material will be screened out from the drum screen, and the qualified material will go directly to the next packaging part.
