Stable material supply in fertilizer production line improves drum granulator efficiency
The stable material quantity and uniform liquid distribution in the rotary drum granulator are the key to produce qualified particles. When the drum granulator produces compound fertilizer granules, the steam pipe is buried in the material bed, and the sprinkling water pipe is arranged above the material bed.
Under the condition of stable feeding of fertilizer production line, saturated steam not only provides heat but also provides part of moisture to humidify the material. Through the use of steam, the temperature and viscosity of materials are improved, and the moisture content of materials can be reduced in the process of pelletizing, thus reducing the drying load. Moreover, the liquid phase distribution of steam can be more uniform than that of adding water. Only when the liquid phase of the material is insufficient and the material is unstable, water can be added as a supplementary means.
In the process of compound fertilizer production, we have encountered that due to the unreasonable installation of steam nozzle and uneven distribution of material liquid phase, the place where there is more liquid phase of material adheres to big ball, and where the liquid phase is insufficient, the material is difficult to form ball, which affects the formation of particles. In view of this situation, we can increase the steam nozzle to increase the steam receiving area of the material.
