Principle and characteristics of rotary drum granulation process
Date:2020/01/02
Production principle of rotary drum granulation process
Steam is introduced into the material layer in the drum to raise the temperature of the granulated material, dissolve the salt of the granulated material, achieve the high liquid volume under the low moisture content to meet the liquid volume required for the material granulation, and reduce the evaporation water volume of the drying process.
The inner wall of the drum is lined with a number of soft rubber plates or polypropylene plates, and the corresponding positions of the drum are provided with air vents. When the inner lining is transferred from the bottom to the top at the same time as the drum, the inner lining will sag due to the self weight, so that the materials adhered to the inner lining will fall down due to the gravity, so as to achieve the function of automatic cleaning of the knots.
During operation, the operator can observe the balling of materials at any time, and take corresponding measures in time as required to ensure the normal operation of the system.
1. From feeding to finished product packaging, it is completed in a continuous production equipment with optimized combination. Comply with the requirements of national regulations on non landing of materials;
2. The equipment is suitable for various kinds of fertilizer as raw materials, can be used in npk fertilizer manufacturing process with low, medium and high concentration, and has high pelletizing rate, round particles, high smoothness, beautiful appearance and good commodity performance;
3. In the fertilizer production process, the dust is handled well, and there is no pollution to the surrounding environment.
4. The equipment adopts the drying process of low temperature and large air volume, which can produce organic, inorganic and biological bacterial fertilizer.
