How make organi fertilizer granules with drum granulation equipment

1. In the solid granulation process of rotary drum granulator, urea, ammonium chloride, ammonium sulfate, potassium chloride and other single base fertilizers are used as raw materials and mixed in a certain proportion (mainly determined by the local market demand and soil test results)).

2. Then use fertilizer mixer to mix the dispersed raw materials evenly and crush them to a certain fineness. Next is the main necessary step – granulation, here you need a drum granulator.

3. The material is sent to the drum granulator by belt conveyor, and agglomerates to form particles through a series of humidification and heating processes.

4. The particles here are only semi-finished products. They need further treatment, including drying, screening, cooling and packaging. After all these steps, high quality compound fertilizer products can be obtained.

Drum granulator is the key equipment of NPK fertilizer granules production line, which is suitable for cold and hot granulation in large and medium-sized compound fertilizer plants. It and ordinary fertilizer granulator are wet granulation. By adding a certain amount of water and steam, the raw materials in the drum will become even and moist in the granulation process. Then, as the drum rotates, the material will combine and roll into particles. The fertilizer particles are spherical with a diameter of 3-4mm.

Why choose?

1. High granulation rate, drum granulator can adjust speed and control granulation.
2. Using solid granulation method, raw materials are easy to obtain and processing is relatively simple.
3. Liquid and steam injection is easy, and pipes and frames are provided.
4. Low investment, low production cost and high return.
5. The drum granulator uses the corrosion-resistant rubber engineering plastic as the lining to better protect the material from drum damage.
6. The particles produced belong to the secondary processing of base fertilizer, so there is almost no environmental pollution problem.
7. High quality steel and gear, stable operation, low noise.
8. Equipped with armrest shovel to help clean the roller.

How to screen unqualified fertilizer out in production?

Feeding preparation of rotary drum screen fertilizer production line
As the necessary equipment for NPK fertilizer and organic fertilizer production, roller screen has the advantages of high efficiency, low noise and less dust. And in the normal use and maintenance, the service life of the screening machine is also very long, easy to clean and replace the screen.

Preparation before commissioning of screening machine:

1. After the screening machine is installed and checked to be qualified, the test run can be carried out. Before testing, all parts of the organic fertilizer production line should be carefully inspected to ensure that they have been correctly installed as shown in the figure, that the fasteners are secure, and that there are obstacles around the screen body that hinder fertilizer operation.

2. Place the rectangular access door in the open position and manually rotate the web drum to observe whether the comb web cleaning mechanism is stuck or rubbed. If so, it can be adjusted by adjusting the bolt

3. Check whether the bearing pedestal and gearbox are well lubricated and whether the oil level is appropriate

4. The power connector shall be firm and reliable with good insulation and correct grounding.

1. When the screening machine of organic fertilizer equipment runs smoothly, start the feeding and discharging equipment of feeding test.

2. After normal discharge, close the seal isolation cover (the seal isolation cover should always be in the closed position during normal operation).

3. The screening machine screens the particles formed by the drum granulator, and checks the particle size of the discharged materials for leakage and dust.

4. After running for half an hour, please check all parts carefully and deal with the problem in time.

5. In the process of work, please check the operation frequently. If abnormal operation or abnormal noise is found, it shall be shut down in time, and the cause shall be checked in time to eliminate the fault.

The prospect of organic fertilizer industry is very good. Especially in recent years, with people’s attention to food safety, the expectation of organic food, ecological agriculture, sustainable agriculture and green ecological agriculture is higher and higher. We all hope that when we enjoy the delicious food, we don’t have to worry about the hormone problems and the discomfort caused by the excessive use of chemical fertilizers and pesticides.

1. Raw material composition: mainly determined according to local market demand and local soil test results; go to https://compostturnermachine.com/  get profesional machines and solutions in this process.

2. Mixing : the prepared raw materials are evenly mixed to increase the uniform fertilizer effect content of the whole fertilizer particles, and the horizontal mixer or pot mixer is used for mixing;

3. Agglomeration and comminution: the large agglomerates mixed and stirred evenly are comminuted to facilitate the subsequent granulation process. Chain crusher is mainly used;

4. Material granulation: the crushed materials are evenly stirred and transported to the fertilizer granulator by belt conveyor for granulation (drum granulator, double roll granulator or disc granulator can be used). The links in the process of organic fertilizer production;

5. Primary screening: the preliminary screening of semi-finished products and unqualified particles is usually returned to the mixing and for post-treatment through the drum screening machine;

6. Particle drying: the particles made by granulator and screened by first level are sent to the dryer to dry the moisture in the particles, so as to increase the strength of the particles and facilitate storage. Drum dryer is usually used;

7. Particle cooling: the temperature of dry fertilizer particles is too high, and it is easy to agglomerate. After cooling, it is easy to pack and transport, and can be cooled by cooler;

8. Secondary classification of particles: the cooled particles are classified, and the unqualified particles are crushed and granulated, and then the qualified products are screened out and screened by the secondary drum screen.

9. Finished particle coating: coating qualified products to increase the brightness and roundness of particles and make the appearance more beautiful. Generally, coater is used for coating.

10. Quantitative packaging of finished pills.
