Requirements for humidity and temperature of organic fertilizer granulation machine
In addition to the process of turning and throwing fermentation, the process of organic fertilizer granulation machine is more difficult. In addition, the granulation temperature has a great influence on the water content. The granulation of dry powder materials must be carried out at a temperature higher than the room temperature, otherwise the granulation needs a higher water content to maintain the optimal liquid phase amount during granulation.
The higher water content not only increases the drying load, but also with the increase of drying temperature, the salt in the fertilizer will further dissolve to form a slurry containing a large amount of liquid phase. If there is no large amount of dried fine powder as the return material, the slurry in the dryer will agglomerate when the dissolution rate is higher than the drying rate and produce slurry in the wall Scab and "big ball" phenomenon not only affects the granulation effect of fertilizer granulation machine, but also makes the whole organic fertilizer processing system unable to run normally.
My company produces fertilizer granulation machine has disc granulator, npk fertilizer granulator, double roller granulator, organic fertilizer granulator machine, drum granulator, flat die pelleting machine, and ring die pelleting machine. Fertilizer granulator machine price concessions, stable operation, convenient maintenance, quality assurance, the majority of users like!
