fertilizer granulator Jul 20, 2023

At present, there are many kinds of Manure products on the market, and their production processes are also diverse. Different production processes have their own advantages and disadvantages. Among them, the extrusion granulation process is simple, easy to operate, zero discharge of “three wastes”, high automation, large output, and the product is not easy to agglomerate. It stands out from many processes and is increasingly favored by enterprises.

The granulation characteristics of the roller extrusion granulator: Extrusion granulation is a dry granulation process in which solid materials rely on external pressure to agglomerate. The material particles are close together under high pressure, and the generated molecular force, electrostatic force, and other forces cause the particles to tightly bond together. Common extrusion granulation methods include roller extrusion granulation, spiral extrusion granulation, and disc die extrusion granulation.

The process of roller extrusion granulation machine: The roller extrusion granulation process adopts German roller compression granulation equipment, which uses the strong pressure generated by the roller press to instantly extrude the powder material into shape, and then obtains qualified products through crushing, screening and other processes.

The working principle of the roller extrusion granulator: After materials with different physical properties are reasonably matched and metered and mixed, they are transported by a bucket elevator, adjusted for humidity, and distributed by an automatic feeder into a pair of reverse rotating roller presses. Under the extrusion of the rollers, they form regularly shaped pieces of material, which are then crushed, screened, polished, and anti caking processes to achieve uniform particle size and hardness standards Compound fertilizer products with full particles.

The roller extrusion granulator is a key equipment for compound fertilizer granulation, with advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and matching with corresponding equipment to form a small production line, which can form a certain capacity of continuous and mechanized production. Adopting the eugenic formula, without drying, produced at room temperature, the product is rolled and formed in one go, ensuring that the product quality meets the technical requirements of compound fertilizers. It is an updated product for the production of high, medium, and low concentration specialized compound fertilizers for various crops and the energy-saving and consumption reduction of the compound fertilizer industry.

Organic fertilizer granulator is mainly used to granulate organic fertilizer to form fertilizer granules of various specifications, which is convenient for packing and transportation. So what is the need for it?

Organic fertilizer granulator is a member of the organic fertilizer production equipment. Its purpose is to make the organic fertilizer into uniform granules, and to make fertilizer granules of various sizes and sizes according to the actual needs of customers.
Due to the increase in the use of organic fertilizer in agriculture, the use of chemical fertilizer has been reduced. To a certain extent, the soil has been kept in a more healthy state and sustainable development. The raw material of organic fertilizer comes from animal feces collected by animal farms. Combined with the crushing of plant straw, the organic fertilizer we want is produced by fermentation. It not only solves the pollution problem of animal manure, but also carries out green environmental protection production to the end.

The necessity of organic fertilizer granulator is reflected in the convenience of packing, weighing, storage and transportation, so as to make the organic fertilizer more weighing and quantitative. If you still have something you want to know about, please contact Tianci heavy industry.

Organic fertilizer granulator is a new type of pelletizing equipment for organic fertilizer pelletizing. There are many kinds of granulators for organic fertilizer, including wet granulation, extrusion granulation and disc granulation. The particle size can be adjusted according to the different moisture content. If it is used for extrusion granulation, the moisture content of raw material used for extrusion granulation should not exceed 15%, because if the moisture content is too large, it is easy to cause the extrusion water turbulence and corrode the machinery and equipment. 
Organic fertilizer production process can be made into: spherical granular, cylindrical, flat spherical. The granulator equipment used is different due to the different particle shape. The materials produced by disc granulator, rotary granulator and agitating gear granulator are spherical; the organic fertilizer produced by opposite roller extrusion granulator is flat spherical, and the particles formed by flat die granulator and ring die prlleting machine are cylindrical.

What are the equipment required to open a small organic fertilizer factory?

fertilizer granulator May 24, 2023

The equipment required to open a small organic fertilizer plant is mainly related to the production process of the plant, and is generally divided into the following situations:

1. Produce fermented organic fertilizer without further processing. In this case, only a mobile tipping machine is needed to handle it. The main purpose is to evenly mix the materials during the fermentation process, making the fermentation more uniform and sufficient, and accelerating the fermentation speed. The starting price of such a tracked tipping machine is only over 50000 yuan.

2. Production of powdery organic fertilizer. Powdery organic fertilizer is crushed on the basis of fermented organic fertilizer, and the processing of organic fertilizer requires a complete set of equipment. The complete set of organic fertilizer equipment includes a fermentation reactor, a semi wet material crusher, a horizontal mixer, a drum screening machine, and a belt conveyor. These equipment can form a simple organic fertilizer production line, and the produced organic fertilizer is powdery organic fertilizer. The production process of powdered organic fertilizer mainly involves fermenting and maturing the raw materials, crushing them with a crusher, and finally using a drum screening machine to remove impurities. Finally, they can be packaged into bags. The price of powdered organic fertilizer processing equipment is around 150000 yuan.

3. Another production process of organic fertilizer is granular organic fertilizer. The organic fertilizer produced by the production line of granular organic fertilizer is granular, and the market price of granular organic fertilizer is about 600-1500 per ton. The required equipment includes: fermentation tipping machine, feeding silo, crusher, mixer, granulator, dryer, cooler, screening machine, packaging machine, and belt conveyor. The production process of granular organic fertilizer is based on the granulation of powdered organic fertilizer, so it is necessary to add organic fertilizer granulation equipment. Before granulation, the water content of the raw material is often increased, so the granulation rate is high, Therefore, the organic fertilizer that has been granulated contains a certain amount of water, which needs to be further processed through equipment such as an organic fertilizer dryer and organic fertilizer cooler. Then, qualified particles are screened using a drum screening machine to complete the entire process of granular organic fertilizer. The starting price of small granular organic fertilizer processing equipment is around 350000 yuan.

Treatment process of chicken manure using organic fertilizer production equipment

The complete set of chicken manure organic fertilizer equipment is a combination of organic fertilizer production equipment that uses animal manure (chicken manure, cow manure, pig manure, sheep manure), crop straw, mushroom residue and other organic raw materials as the main raw materials to produce organic fertilizer particles. The organic fertilizer production line has gradually become the mainstream equipment in the market with the increasing demand for small-scale chicken manure equipment production lines advocated by the country.

The processing of commercial organic fertilizer from chicken manure and cow manure requires two steps: the early fermentation part is a necessary processing step for any form of organic fertilizer, and a fermentation tipping machine is needed to assist in the processing process. The later processing process mainly selects the corresponding production equipment based on the type of fertilizer required by the customer, such as a pulverizer and screening machine for powdered organic fertilizer, and a granulator needs to be added to the previous foundation for granular organic fertilizer Drying machines, cooling machines, etc.

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

fertilizer granulator May 17, 2023

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

fertilizer granulator May 12, 2023

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.
