As everyone knows, the disc granulator machine is commonly used in the NPK fertilizer production line and organic fertilizer production line.


When in production, the factors affecting the granulation of the disc fertilizer granulator machine are mainly the disc diameter, the inclination of the disc, the disc edge height, the rotation speed, the material liquid spraying position, and the position of the scraper plate.

The inclination angle of the disc granulator is determined according to the natural angle of repose of the wetting powder before granulation. For example, the natural angle of repose of potassium chloride is 36 °, the inclination angle of dipotassium phosphate is 31 °, and the angle of repose of heavy calcium is 31 °~ 35 ° and so on. When the angle of inclination is less than the natural angle of repose of the wet powder, the material will stick to the disc and rotate with the disc; as the inclination increases, the rotation speed should increase, otherwise the material will easily accumulate on the lower part of the disc and slide, and no drop and upper and lower Scroll down. However, with the increase of the inclination angle, the rotation speed increases, the material residence time becomes shorter, and the particle size of the overflowing particles becomes smaller, so it should be determined according to specific conditions, generally 40 ° ~ 60 °, which can be adjusted by the granulating machine inclination angle adjustment handwheel .

The ratio of the edge height of the disc granulator to the diameter of the disc is generally 0.12 to 0.17, and its diameter can be calculated from the production intensity obtained by experiments or actual production assessment.

The disc granulator has many advantages: uniform product particles, good automatic classification ability, can control the solution to be sprayed on fine particles, so the granulation efficiency is high, large particles are generated less, and the return ratio is small; all operations Intuitive and easy to control, so that the operating conditions can be found relatively quickly during operation, timely adjustment, and strong adaptability to the flexible change of the formula; the production of various products has greater flexibility, a wide range of granularity control; simple structure, Equipment investment and operating costs are relatively low, and are widely used in medium and small compound fertilizer plants. However, there are also some disadvantages: mainly the collection of dust and smoke is difficult, and the ammoniation cannot be performed efficiently. Dust and exhaust gas are prone to spills, and practical measures must be taken to control it. At the same time, it is limited to granulation using slurry or melt with low viscosity..
 

Sheep manure organic fertilizer production line:
First. Mix the sheep manure with the crop straw. The amount of the sheep manure depends on how much the water content of the sheep manure is determined. According to the fermentation process, the water content is required to be within 45%, that is, the material is kneaded into a mass, and the water can be seen. Will not drip down, loosen the group will spread out. Then, the cornmeal and the required strains are added. The reason for the cornmeal is that the sugar content can be increased to promote the rapid fermentation of the strain.


Second, the configured materials are added to the material mixer for mixing, and the mixing is required to be uniform and transparent, and no raw blocks are left.

Third, the mixed materials are piled in a fermentation tank or grooves with a width of 2 to 6 meters and a height of 1.0 meters to 1.5 meters, and are repeatedly turned over and thrown every other day using a compost turning machine.

Four, under normal circumstances, in the fermentation tank, the temperature will rise after stacking for 2 days, and it will be odorless after 2 days. After 3 days, it will become fluffy and loose. After 2 days, compost will emit fragrance, 15 days, it can be fat.
1. In the fermentation tank for 2 days, the temperature will rise to 60 ° C to 80 ° C, which will kill bacteria and remove insects.
2. On the fourth day in the fermentation tank, the odor is eliminated; then on the seventh day, the material in the tank will become loose, dry and covered with white hyphae.
3. fermented in the pool to the ninth day, the nine will emit a fragrance, basically similar to the koji.
4. Fermentation to the tenth day in the tank, the material will be fermented and cooked, and sufficient.
5. On behalf of the end of the fermentation stage, the material can be removed to the next step with a forklift or the like.

Five. The material moved by the forklift to the pulverizing process is pulverized by a semi-wet and high-humidity material pulverizer, and then mixed by a mixer machine, transported to fertilizer granulator machine by a conveyor, and granulated into granules, It is sent to the dryer by the belt conveyor, dried and dried, and then cooled into the cooler. Then the conveyor is sent to the screening machine for screening. The required particles of more than 95% will enter the next process, and about 5%. The granules are transported to the pulverizer for re-pulverization and granulation, and the granules that meet the standards are fed into the coating machine for coating. The coating can maintain the nutrients, and after coating, it is packaged by an automatic packaging machine. In this way, the sheep manure organic fertilizer is processed and packaged and can be sold in the warehouse.
 

The fertilizer granulator machine is important equipment in the production of granular fertilizer. We are fertilizer machine manufacturers, producing different fertilizer machines, and different types of fertilizer granulators. Let us look at the advantages and disadvantages of different granulators.


1. Roller press granulator belongs to dry granulation, without drying process, high granulation density, good fertilizer efficiency and full organic content; it also saves the money to buy dryer and cooler, and does not need to burn coal later. This saves a lot of money. However, the granulation of the extrusion granulator belongs to an oblate shape. It is easy to get stuck when the field crops are planted, and the fluidity is not very good. Therefore, if it is used for the organic fertilizer produced by the machine farmers, it is recommended to use this granulation process with caution. Do compound fertilizer and compound fertilizer.

2. Rotary drum granulator is a process that has been used in compound fertilizer granulation. It can also be used to produce organic fertilizer, but the granulation rate is low. If organic inorganic fertilizer is produced, this process can be selected.

3. disc granulator is a relatively traditional process, we prefer this fertilizer granulator machine, the granule is smooth, good to sell, the only drawback is the low density; people are now pursuing new, new methods of granulation, so use There are fewer people.

4. New organic fertilizer granulator, this kind of granulation process is a hot product sold by our factory, and it is also a product favored by customers. This process has high output and smooth processing. If it is added with organic fertilizer throwing machine, the granules can be comparable with that of disc granulation. However, it is necessary to purchase a dryer, a cooling machine, and the organic fertilizer package of such a process is expensive.

5. The flat die granulator has the highest grain density, and the particles will not be scattered during the sales and transportation process, but the round thrower must be added in the later stage to realize the finished product of the round grain.

The above are the advantages and disadvantages of the mainstream granulation process on the market. If you can choose the granulator you want here, then here are some suggestions. If your investment funds are limited, or the sales market has not been opened, I suggest that you can first put on a powdered organic fertilizer production line. The whole set of organic fertilizer equipment has low price and good quality, which will help you to open up the market. After the sales market is opened, you can increase the production and purchase equipment, and then do the pellet organic fertilizer production line.

If you pay more attention to the sale of organic fertilizer granules, we recommend that you use the disc granulation process, although traditional, but the spheroidal smoothness is very good. If you want to neutralize it, then choose a new organic fertilizer granulation process with high output.

The disc granulator machine is mainly used in the NPK fertilizer production line and organic fertilizer production line to produce various granular products; it’s also used in pharmaceutical products, fertilizers, feeds, etc. Adopting the overall arc structure, the granulation rate can reach above 93%. The granulation tray has three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

 
Disc fertilizer granulator machine working principle:
The raw meal powder is uniformly wetted by the atomized water in the mixer to form a spherical core having a uniform particle size, and then fed into a ball plate for ball formation. The moisture of the ball should be controlled at 12-14%. Most of the water should be added in the twin-shaft mixer. Only a small amount of supplementary water is added to the ball plate, and the amount of water added is controlled to be about 0 to 3%. The dry powder granulation is directly added to the ball-forming plate, and the proper amount of water is sprayed. The raw material nucleus enters the spherical disk and is subjected to centrifugal force, friction and gravity in the disk, and moves along the parabola. Due to the cohesiveness and plasticity of the material, the cores are bonded to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the height of the disc edge, the rotation speed and the moisture are constant, the balls of different particle sizes roll downward from the edge of the disc at different disengagement angles due to different gravity. During the continuous rolling process, the ball continuously discharges the water in the ball out of the surface. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the ball has certain strength, and then the disk is rotated with the tilting of the disk. The sides are discharged out of the pan.

Disc granulator performance advantages:
1. The raw materials are suitable for a wide range of applications. They can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce various concentrations and various types (including organic fertilizer, inorganic fertilizer, and magnetic fertilizer etc.) of compound fertilizer.
2. The disc granulator is light in weight, low in height, and flexible in process;
3. The machine has simple structure, convenient adjustment and superior performance.
4. The use of unique unpowered combination scraper integration reduces auxiliary power consumption.
5. high ball formation rate, large rounded particle strength, intuitive operation, easy maintenance and so on.

Fertilizer granulator machine is the core equipment for fertilizer manufacturing process. As one of leading fertilizer machine manufacturers in China, in addition to the disc granulator, we also produce other types of fertilizer granulator machines, and other equipment such as compost turning machines, mixer machine, crusher machine, etc.
 

The cow manure organic fertilizer production line uses crops such as straw and rice bran as fillers, and then sprinkle the biological strains through the turner. It is turned over once every 1-2 days. It can be completely decomposed in 7-10 days and made into a national standard organic fertilizer.


The technical route for the production of organic manure from cow dung includes two major steps: raw material aerobic composting process and commercial organic fertilizer fertilizing process.

Among them, the aerobic composting process is used in the fermentation process. Modern aerobic composting is a method in which the manure is used to stabilize and harm the cow dung under aerobic conditions by using aerobic microorganisms, and then converted into high-quality fertilizer. Before the composting, the cow manure raw material is pretreated to meet the fermentation conditions such as water and carbon-nitrogen ratio. In the fermentation process, the compost turning machine is used to turn over and accelerate the fermentation speed. After composting, the cow manure can be fermented and then enter the fattening process. According to the need, it can be further processed into powdery organic fertilizer and granular organic fertilizer products, or mixed with chemical fertilizer to make various organic and inorganic compound fertilizer products to realize commercial production. .

The fertilizer manufacturing process requires a crusher, a mixer, a cooling and drying machine, a fertilizer granulator machine, a sieving machine, a packaging machine, a dust removal system, and the like.
1. The pulverizer comprises a half wet material crusher machine;
2. The mixer has an optional horizontal mixer or a disc mixer or a twin-shaft mixer;
3. The dust removal system consists of a settling chamber and a dust collecting room.
4. The cooling and drying system can be used to dry and cool the fertilizer granules.
5. The fertilizer granulator machine has organic fertilizer granulator, disc granulator, drum granulator, etc;
6. The screening system is mainly completed by the drum screening machine, and the first-stage screening machine and the second-level screening machine can be set to make the yield higher and the particles better;
7. The finished packaging system generally includes an electronic quantitative packaging scale, a silo, an automatic sewing machine, and the like. In this way, the batch-free production of the fully automatic cow manure organic fertilizer production line can be realized.
