Working principle and maintenance method of disc organic fertilizer granulator

fertilizer granulator May 17, 2023

The disc organic fertilizer granulator can be used for powder, uniform and viscous materials. The materials are transported to the rotating disc of the granulator, and the appropriate amount of water is sprinkled on the materials. Through the centrifugal force of the disc and the friction force in the material rotation, plus the gear rotation structure, the materials can be continuously kneaded and squeezed, and the particles can be formed quickly. At the same time, due to the role of centrifugal force, the particles formed are also very uniform.
The reducer and motor of disc organic fertilizer granulator are driven by flexible belt, which can start smoothly and slow down the impact force. The bottom of the plate is reinforced by a number of radiation steel plates. The thickened, weighted and solid base design does not need to be fixed by anchor bolts, and the operation is stable. The main gear is quenched with high frequency, and its service life is prolonged. The extension of life also means the reduction of production cost.

As the main equipment of fertilizer granulation, the quality of the organic fertilizer machine must be guaranteed. In addition to the manufacturers, the follow-up maintenance depends on the user’s own care and care during daily use, regular maintenance, regular inspection of equipment parts and accessories to see if they are loose or cracked. When they are not in production, they should be cleaned up in time, and they should be added when they are used again Lubricating oil. 

Different advantages and processes of powdered and granular organic fertilizers

fertilizer granulator May 17, 2023

There are two main types of organic fertilizers processed by organic fertilizer production equipment: powdered fertilizers and granular fertilizers. Granular fertilizers are more commonly used in daily processing. The main purpose of using organic fertilizer production equipment to produce granular organic fertilizers is to facilitate bagging and transportation to prevent secondary fermentation of organic fertilizers. In addition, in terms of sales level, granular organic fertilizers are better sold.

Advantages of granular organic fertilizers:

1. It is more convenient to apply. Some organic fertilizers have a relatively light weight and are easily dispersed by the wind when applied in the field, making them easy to apply as granules.

2. Some inorganic components can be added to the fertilizer to improve fertilizer efficiency. If inorganic components are added to the powder, it is easy to absorb moisture and clump.

3. To obtain powdery materials, it is necessary to have low moisture and be crushed. The major limiting factor in organic fertilizer production is that the moisture cannot be removed and needs to be dried. Granulation can be done without drying, and high heat is generated during the granulation process, which only needs to be cooled, making it very convenient.

Advantages of powdered organic fertilizers:

Powdered organic fertilizer is an organic fertilizer that has not undergone granulation or drying. Accounting for over 80% of the domestic market share. Compared to granular ecological organic fertilizers, they have the advantages of low investment, low production cost, less nutrient loss during processing, low price, and less ecological pollution, and are generally accepted by planting parks and fruit and vegetable bases. The disadvantage is that the shape is not aesthetically pleasing and is not suitable for machine seeding and application.

The production of powdered organic fertilizers is relatively simple. The production equipment mainly consists of five major components: organic fertilizer stacker, forklift, quantitative feeder, organic fertilizer crusher, and screening machine (drum screen or vibrating screen).

Four sets of belt conveyors are required to connect the equipment to form a complete production line:

1. A belt conveyor is installed above the crusher to connect the screened large raw materials.

2. A belt above the screening machine is connected to the fermentation raw materials.

3. A belt below the screening machine is connected to the screened finished material, which is sent to the processing site for weighing and packaging.

4. The warehouse needs a conveyor for loading.

NPK fertilizer production line of roller extrusion granulator is widely used in powder processing. It is characterized by no need to humidify or heat the material, and the material can be directly processed into particles. It can be used for organic and inorganic fertilizer granules, as well as for the processing of feed granules.
NPK fertilizer production line adopts dry extrusion granulation process. There is no waste water, no waste gas emission and no environmental pollution. Extrusion granulation process is short, easy to operate, easy to realize automatic production control, and improve the production efficiency. There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are relatively wide.

NPK fertilizer production line of roller extrusion granulator
1. According to the proportion requirements, add qualified raw materials into the mixer and mix them evenly.
2. Transfer to the disc feeder and remove metal material from the material during transmission.
3. The materials in the disc feeder evenly enter the extrusion fertilizer granulator machine. The material is forced to pass between two pressure rollers and is pressed into thin sheets. The flakes are broken into pieces by the coarse crusher under the action of the pressure roller. Sieving. The sieve material continues to be crushed and sieved.
4. Transport the semi-finished products to the finished product screening machine. The screened fine particles are directly returned to the disc feeder. The large particles are crushed by the mill and then returned to the disc feeder.
5. The screened qualified products will be transported to the automatic packaging scale for weighing, packaging and storage.

Advantages of disc granulators for organic fertilizer production lines

Once the diameter of the disc is determined, the height of the disc can basically be determined. Generally speaking, the larger the diameter, the higher the height of the disc. However, the height of the disc can affect the ball time of the fertilizer on the disc. The particles generated on the disc will be affected by the friction coefficient between the raw material and the disc surface. The difference produces a grading effect. Small particles stay close to the bottom of the disc, while larger particles are discharged beyond the edge. The higher the disc edge, the longer the ball formation time. The disc granulator is an organic fertilizer granulator. If the height of the disc is too low, the pelletizing time will be short, and the particles that come out are relatively small in size. Therefore, on the one hand, the height of the pan can affect the size of the particles discharged from the pelletizing pan, and on the other hand, it can also affect the output. Because if the material stays in the pan for too long, the discharge speed of the product will be slower, the larger the particles of the product, the more particles that do not meet the standard, and the lower the rate of ball formation. Therefore, it is reasonable to choose a high plate height. important.

In the fertilizer production process, since the particles will gradually grow up as they roll down along the surface of the disc, the more the material rolls in the disc per unit time, the faster the particles will grow up, that is, the working efficiency of the granulator It is proportional to the speed of the granulator. Because the basic powder fertilizer rises with the rotation of the disc with a certain slope, it rolls down under the action of gravity, and at the same time, it is thrown to the edge of the disc due to the centrifugal force, these powders collide and fuse with each other, and The liquid phase is bonded together by the surface tension. Therefore, the speed of the speed will affect the bonding and pelletizing process of the powder-grain fertilizer on the one hand. If the rotation speed is too fast, the powder fertilizer will not be formed in time, and it will be thrown out of the disc; too slow rotation speed will cause the powder particles to form a ball for too long, making the diameter of the particles overflowing the disc larger than the standard requirement; on the other hand, with the disc As the inclination angle increases, if the rotation speed of the disc is too slow, the material will accumulate in the lower part of the disc, and the drop and repeated rolling up and down will not occur, which will also affect the ball formation rate. We have some types of organic fertilizer machine.

As the speed of the pelletizing disc increases, the centrifugal force increases, which will make the particles close to the edge of the disc, preventing the particles from rolling down, and a funnel-shaped vortex will appear on the disc surface. In order to maintain the effective use of the disk surface area, the inclination angle of the disk must be increased while increasing the speed. As the inclination angle of the disc increases, the end speed of the particle rolling will increase accordingly, so the inclination angle of the disc should be maintained at a limit value to prevent damage to the rolling and granulation of the material. Therefore, the rotational speed of the disc is also a major influencing factor.

In the organic fertilizer production process, the material pelletized by the disc is generally fermented, and the fermentation tool used at this time is a compost windrow turner.

The role of biological organic fertilizer granulator in processing organic fertilizers

fertilizer granulator May 9, 2023

The role of bio-organic fertilizers Bio-organic fertilizers have different functions due to the different types of microorganisms contained. In summary, they have the following effects.

⑴ Nitrogen fixation, such as root nodules and nitrogen-fixing bacteria, they can fix nitrogen in the air under suitable environmental conditions and provide nitrogen nutrition for crop growth. It is estimated that the annual biological fixation of nitrogen by crops can reach 101 million tons.

⑵Nutrient release effect Microorganisms decompose some substances in the soil that are difficult to be absorbed and utilized by crops and convert them into effective nutrients that can be absorbed and utilized by crops. For example, silicate bacteria can not only decompose difficult-to-decompose minerals such as potassium feldspar and mica in the soil, and release the fixed potassium, but also promote the conversion of insoluble phosphorus in the soil into a form that can be used by crops.

⑶ Growth-promoting effect After applying microbial fertilizer to the soil, it not only increases the nutrient content in the soil, but also promotes the synthesis of various vitamins, enzymes and other substances beneficial to crop growth, stimulates the growth of crops, and assists crops in absorbing nutrients. In the fertilizer production process, the addition of biological agents is before the fertilizer packaging.

⑷Disease resistance After some microorganisms are inoculated in the soil, they multiply in the roots of crops and become the dominant bacteria in the rhizosphere of the crops for a period of time, inhibiting or reducing the reproduction opportunities of pathogenic microorganisms, and some microorganisms will also have resistance to pathogenic microorganisms. Although microbial fertilizer can provide nutrients for crop growth and stimulate and promote crop growth, its role is still limited after all. In crop production, organic fertilizers and chemical fertilizers are mainly used to provide nutrients for crop growth. According to the different organic fertilizer materials, the selected organic fertilizer granulator is also different.

⑸Many raw materials in nature contain many beneficial microorganisms, but once these raw materials are applied to the soil, the microorganisms in them will be eaten by countless microorganisms in the soil. Therefore, it cannot survive stably in the soil, and its effect is difficult to show. However, if the beneficial bacteria are added to the fermented organic fertilizer after fermentation, the fermented organic fertilizer itself is the expansion medium, which will cause the bacteria to proliferate in large numbers. At this time, applying microbial organic fertilizer to the soil will quickly form a dominant population in the soil, which can play a good role in the root system of the crop. Fermented organic fertilizer has a good effect on exerting microbial activity. Welcome to buy our company’s organic fertilizer machine.
