Producing the organic fertilizer granulator using the fertilizer granulator machine.Different type and model of organic fertilizer granulator machine can be used to produce the organic fertilizer granulator.How to improve the granulation rate of the rotary drum granulator?
In the fertilizer manufacturing process,the new type organic fertilizer drum granulator is a common granulator,which mainly uses high-temperature steam to make raw materials humidified to the granulation state.After the granulation of Huaqiang new type type organic fertilizer drum granulator,the particl temperature is very high.In the next drying process of organic fertilizer particles,the heat energy consumption of drying is saved,which is not efficient and engery-saving,and the granulation rate is up to more than 90%.
In order to improve the granulation rate of the new type organic fertilizer drum granulator in organic fertilizer production line,in addition to selecting a high-quality product,the granulation rate and output of the granulator can also be improve the granulation rate of new organic fertilizer drum granulator:
First,the time and frequency of material rolling in the new type of organic fertilizer drum granulator is the primary factory to determine the pelletilizing rate and particle roundness.The principle of rotating drum granulation is that the material depends on the surface tension,the appropriate liquid phase,the extrusion pressure generated by roller press which the roller press granulator machine is also to be designed and used in npk fertilizer manufacturing process in most of time,and correct movement direction of the material in the granulator is centered on small particles,which absorb and adhere to the ball in the rolling process.The higher the rolling frequency in a certain period of time,the higher the pelletilization rate is,and the rounder the particles will be after forming.In the process of production,we have encountered two situations due to the different friction between the material and the barrel wall of the granulator.
1.The internal surface finish of te granulator is large,which reduces the friction between the material and the cylinder wall,and weakens the upward movement force of the material.If the material does not roll,it will not produce particles.In view of this situation,we can solve it by adjusting the rotating speed of the new type of organic fertilizer drum granulator and installing a small-scale plate inside.
2.The material in the organic fertilizer drum granulator sticks to the walll seriously,the friction between the material in the granulator and the cylinder wall is enhanced,and the material in the granulator is lifted too high,which causes the material to be thrown down from the top,until the particles formed are not round and too many large particles.We think there are two reasons for this situation:on the one hand,there are too many stickly materials ,which we adopt.On other hand,the inside of the granulator is not smooth,which can be solved by changing the inside material and increasing the inside finish of the granulator.

The design of npk fertilizer production line by rotating drum granulation is that there is a steam pipe embeded in the feed bed,and a spray is arranged above the feed bed.Under the condition of stable production supply,the saturated steam provides part of water while providing heat,which increase the moisture content of the material.Through the use of steam,the temperature and viscosity of the material are increased,so that the moisture content of the mateiral can be reduced in the process of balling,thus reducing the drying load, and the liquid phase distribution of adding steam can be more uniform than adding water. Only when the liquid phase of the material is insufficient and the material is unstable, can the water be added as a supplementary means. In the process of production, we have encountered that because of the unreasonable installation of the steam nozzle and the uneven distribution of the liquid phase of the materials, the places where there are many liquid phases of the materials are stuck into a big ball, and the places where the liquid phase is insufficient, the materials are difficult to form a ball, which affects the formation of the particles. In view of this situation, we can increase the steam nozzle to improve the steam receiving area of materials.
In conclusion,in order to improve the granulation rate of the new type organic fertilizer drum granulator,it is necessary to stickly control the water content,carry out the water ratio according to the provisions of the fertilizer equipment manufacturer,and pay attention to the methods in the production process at ordinary times,so as to improve the granulation rate and output of the new type organic fertilizer drum granulator.
