The organic fertilizer granulator consists of several parts. First, it’s the collection part of the device. Secondly, it is the most important transmission component and also a bracket device with special technology. Finally, there are conveyor belts and auxiliary wheels, and different granulators have different granulation characteristics.

1. The principle of rotary drum granulator is that the material relies on the surface tension, an appropriate amount of liquid phase, and the extrusion force generated by the rolling between the materials.

2. The processing operation of the double roller granulator equipment adopts the non-drying and normal temperature process, the particle strength is high, and the bulk specific gravity increase is more obvious than other granulation methods, especially suitable for occasions where the product bulk specific gravity increases.

3. The new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the generated aerodynamic force to continuously realize the mixing, granulation, spheroidization, densification and other processes of fine powder materials in the machine, so as to achieve the purpose of granulation.

4. The control of water content, material quality and water temperature in the operation of the disc granulator of organic fertilizer equipment.

How to reduce the noise of the organic fertilizer granulator in the npk manufacturing process, there are the following suggestions:

1. There may be a problem with the bearing of a certain part of the organic fertilizer granulator, which makes the machine work abnormally, the working current fluctuates, and the working current is too high.

2. The ring die is blocked, or a part of the die hole is detached from the material. If the ring die enters the foreign body, the ring die is out of the circle, the gap between the roller and the die is too tight, the roller is worn or the roller bearing is damaged and cannot rotate, which will cause the vibration of the granulator.

3. The coupling correction is unbalanced, the height and height are deviated, the granulator vibrates, and the gear shaft oil seal is easily damaged.

4. If the main shaft is not tightened, the loosening of the main shaft will cause axial movement before and after the movement, the roller swings obviously, the granulator is noisy, and the granulation is difficult.

5. The wear of the big gear and the pinion, or the replacement of a single gear, will also produce a lot of noise.

fertilizer granulator May 23, 2024

The organic fertilizer pellet production line project is a process that uses organic waste fermented by microorganisms to produce organic fertilizer through granulation.

Process flow of a daily production line for 500 tons of straw granular organic fertilizer

1. Mainly, raw materials containing organic matter (such as sheep manure, pig manure, sludge, chicken manure, duck manure, cow manure) with a moisture content of about 70% are mixed with crushed organic waste (such as straw, corn straw and branches, mushroom residue) and then added with a biological fermentation agent for fermentation.

2. Use a forklift to load the mixed (sheep manure, pig manure, sludge, chicken manure, duck manure, cow manure) and other plant straw into a fermentation and maturation tank, and evenly add fermentation bacteria for maturation.

3. Fermented raw materials can be directly transported to the organic fertilizer crusher for crushing through an automatic material system using a belt conveyor. The crushed materials can be directly transported to the screening machine using a belt conveyor. The screening machine screens out impurities that are not fully decomposed or crushed, and then uses a belt conveyor to transport them to the waste disposal site for processing;

4. After fermentation and crushing, the raw materials are accurately proportioned (bentonite, humic acid) with a forklift into the automatic batching bin and other raw materials (adding nitrogen, phosphorus, and potassium with a total nutrient content of less than 25%) to produce organic and inorganic fertilizer compound fertilizers. After proportioning, they are quickly and evenly stirred by a mixer.

5. It enters the organic fertilizer granulator through a belt conveyor, and a small amount of water is added to the inlet for granulation. The particles formed by the granulator are then transported by the belt conveyor to the rounding machine for shaping

6. After drying and cooling, the particles are sieved by a belt conveyor through a powder screening machine for final product screening. The particles that do not meet the requirements are transported to the waste crusher by a (finished particle 2-4mm) belt conveyor for thorough crushing, and then returned to the granulator for further granulation by the return material belt conveyor.

7. After sieving the powder, the particles are coated by a coating machine and can be added (functional bacteria can produce bio organic fertilizers)

8. After adding functional bacteria to the coating machine, the particles are transported by a belt conveyor to the second screening machine for particle size screening. The particles (2mm and 4mm) can be separated and packaged separately, making them more beautiful,

Advantages of double roller granulator:

1. Low energy consumption and energy saving road roller extrusion granulation is a kind of material granulation at room temperature. Compared with other methods, it does not require drying measures such as fuel and gas.

2. The low investment is due to the saving of the drying process, the low rate of return (about 15% of the total feed of the extruder), the simple process flow and the low investment.

3. The consumption capacity of extrusion granulation is only electricity, and there is no three waste discharge for environmental protection.

The double roller granulator has the characteristics of low energy consumption, high energy saving, low investment, simple operation, and no pollution of equipment emissions. Before the production of the npk fertilizer production line, the installation of the roller extrusion granulator needs to be debugged. Take the right approach:

1. Adjustment of the roller gap: In the npk manufacturing process, sometimes it is necessary to increase the output or bite angle, at this time, the distance between the two compression shafts can be increased, and the distance between the active shaft and the passive shaft can be increased. The steps are as follows: stop the machine, remove the upper rack of the two bearing seats, adjust the adjustment plate between the two bearing seats to the required thickness, the rollers cannot collide between the two rollers, and the minimum should be kept between 0.3-1mm.

2. The alignment adjustment of the ball socket. The ball socket is formed by the dimples on the main roller surface, so there are problems of axial alignment and circumferential alignment:

1) The axial alignment has been adjusted during installation. Generally speaking, it is not possible to adjust. When adjustment is required, tighten or loosen the glands on both sides of the passive bearing seat, thereby pushing the displacement of the eccentric sleeve to be in line with the drive shaft roller. correspond.

2) Align the ring direction, loosen the six connecting bolts between the driven gear and the adjusting sleeve, so that the adjusting device and the driven gear are slightly separated. Since the ball seat adjustment is considered in the design and two adjustment bolts are installed, the dislocation can be adjusted regardless of the dislocation.

How much does it cost to invest in running a chicken manure organic fertilizer factory in rural areas?

fertilizer granulator May 20, 2024

The organic fertilizer production line has different equipment configurations according to the different raw materials, and is divided into three configurations: high, medium, and low. The organic fertilizer production line with medium and low configurations is suitable for small and medium-sized fertilizer factories. The sales range of finished organic fertilizers is in nearby areas, and some processes in the organic fertilizer production process need to be completed manually; Large fertilizer factories need to adopt a complete set of advanced production configurations, and the appearance and nutrient content of the finished products can meet market requirements, which has a significant advantage in the promotion of finished organic fertilizers.

The prices of organic fertilizer production lines with different yields also vary, and suitable plans can be made based on the investment budget.

If producing powdered organic fertilizer for processing, only one fermentation equipment, crusher, and screening machine, needs to be invested. The investment is just over 60000 yuan. If producing granular organic fertilizer, it is necessary to add an organic fertilizer granulator, dryer, and a cooling machine is generally not required for an annual production capacity of 10000 tons of organic fertilizer. The investment amount is about 200000 yuan. The construction site can be large or small, and generally requires 3 to 5 acres of land.

Firstly, after sorting and crushing, chicken manure enters the fermentation stage. This stage is very important as organic waste undergoes deep fermentation here, producing beneficial microorganisms and enzymes.

Next, the fermented organic materials will be dried to reduce moisture content and facilitate subsequent processing. Then, after screening and crushing, the powdered organic fertilizer obtained will undergo formula adjustment to meet the needs of different crops.

Finally, organic fertilizers can be packaged in various bags or forms for convenient storage and sales.

In order to smoothly carry out the above process flow, the supporting equipment of organic fertilizer production equipment is also crucial. Common supporting equipment includes waste crushers, fermentation composters, dryers, screening machines, and packaging machines. These devices can effectively improve production efficiency and product quality, while also reducing labor costs and energy consumption. Of course, the equipment models and configurations required by organic fertilizer production enterprises of different scales may also vary, and the selection should be based on specific circumstances.
