Fertilizer packaging machine can be divided into automatic packaging machine and semi-automatic packaging machine from the degree of automation. The former does not require human involvement in the entire packaging process, while the latter requires some auxiliary cooperation. Of course, the price of the two fertilizer manufacturing equipment is different, and customers can choose according to their own needs.
Semi-automatic packaging machine only needs to hang the bag manually. The weighing method of the equipment can be selected according to the actual needs of the upper weighing and lower weighing. The material falls due to gravity. When the weight is close to the target weight, the unique two-stage control valve ensures accurate weighing of the material.
Compared with manual operation, the advantages of organic fertilizer automatic packaging machine are very obvious. In the entire process of drum granulation, packaging can be completed with a simple operation. In the past, the equipment of the ton bag industry was simple and rough, and the packaging mainly relied on forklifts and manual filling.
This way not only requires a lot of human resources, but also highly polluting materials are easy to cause harm to the human body, especially the work efficiency is much lower than that of fertilizer packaging machines.
With the continuous development and improvement of packaging machines, a variety of products such as single bucket packaging scales and double bucket packaging scales have been derived for users to choose. When purchasing, users can freely choose according to their own materials and packaging needs.
In the production of potassium chloride granular fertilizer, the powder can be granulated by disc fertilizer granulator. The particles produced by disc granulator are spherical and have good strength. It can be widely used in agricultural production.
In the granulation process of disc fertilizer granulator, adhesive needs to be added to form the particles. The binder can be compounded by ordinary inorganic minerals in a certain proportion. When potassium chloride is granulated, the adhesive has synergistic effect.

When applying potassium chloride, attention should be paid to the appropriate potassium application period.
The application period of general potassium fertilizer should be early or not late, and it should be used as base fertilizer and early recovery period. When the application amount of potassium fertilizer is small, it can be used as base fertilizer at one time.
When the application amount of potassium fertilizer is large or the soil texture is light, the application effect of base fertilizer and topdressing is better.
Soil nutrients and fertilization should also be considered when determining the appropriate application period of potassium fertilizer.
In the soil with serious potassium deficiency, the middle soil potassium fertilizer should be fully applied with potassium fertilizer as the base fertilizer, appropriate organic fertilizer as the base fertilizer, combined with topdressing.
Pay attention to the application method of potassium chloride. The centralized application of potassium fertilizer is conducive to improve its utilization rate and achieve good results. However, direct contact with seeds or seedlings is not recommended. For general crops, the combination of soil fertilization and foliar fertilization can be adopted.
Drying process is also the key of NPK fertilizer production line. The fertilizer should be dried after granulation to reduce the moisture in the particles and increase the hardness of the particles, which is very important to the quality of the fertilizer.
1. The installed dryer shall be subject to an empty machine test for not less than 4 hours. In case of any abnormality during commissioning, it shall be handled in time.

2. After commissioning, retighten all connecting bolts, check and supplement lubricating oil. After the test is normal, the load test can be carried out.
3. Before load test run, single air test run shall be conducted for each auxiliary machine. After the single machine test is successful, transfer to the joint test.
4. Ignite the hot air oven to preheat the dryer and start the dryer at the same time. Do not rotate the cylinder to prevent the cylinder from bending.
5. According to the preheating condition, the wet material is gradually added into the drying cylinder, and the feeding amount is gradually increased according to the moisture content of the discharged material.
6. The preheating of the dryer needs a process, and the hot blast stove should also have a preheating process. Sudden fire is prohibited. Prevent local overheating and uneven thermal expansion and damage.
7. Fuel combustion value, thermal insulation quality of each part, moisture content of wet material and uniformity of feeding amount affect dry product quality and fuel consumption. Therefore, it is an effective way to improve economic benefits to make each part reach the state as much as possible.
8. In the working state, the roller frame shall be filled with cooling water.
9. All lubricating parts shall be filled in time.
10. During shutdown, the hot blast stove shall be closed first, and the drying cylinder shall continue to rotate until it is cooled to close to the outside temperature.
12. In case of sudden power failure, close the hot blast stove immediately, stop feeding, and turn the cylinder half a circle every 15 minutes until the cylinder cools down.
The operating procedures of this fertilizer manufacturing process should be careful and professional. Failure to follow this procedure will cause the cylinder to bend.
Granulators used to convert organic fertilizer into thread and teeth can make various materials into specific shapes. This is a special molding equipment.

Biological organic fertilizer rotary drum granulator can make organic fertilizer from rice straw, rice husk, manure and other wastes. It is an important granulation equipment for processing agricultural waste into organic fertilizer. Burning a large number of rice straw causes serious pollution to the environment and affects people’s health. In addition, the effect of straw burning on soil fertility was very low. Processing straw into organic fertilizer with high nutrient content not only avoids environmental pollution, but also has high return, high product quality and low production cost. It is of great theoretical and practical significance to develop biomass fuel and reduce environmental pollution.
Working principle of rotary drum granulator for bio organic fertilizer
Under certain pressure and temperature, the bio organic fertilizer powder is compressed into cylindrical fertilizer by rotary drum granulator. The granulator uses extrusion force and friction force to compact sawdust and straw under high pressure and high temperature in the process of roller and drum movement. The material enters between the drum and the roller. The rotary drum is driven by a motor through a current reducer to rotate and extrude the die hole, and finally form the granular material.
