What is the working principle of the roller extrusion granulator

fertilizer granulator Jul 24, 2024

The working principle of the roller extrusion granulator is based on physical extrusion and bonding mechanisms. Its core components are a pair of rotating rollers, usually composed of two cylindrical rollers with equal diameters, which are installed parallel to the machine frame and can rotate independently. These rollers are usually made of wear-resistant materials, such as high-strength steel, to withstand continuous material processing.

When the roller extrusion granulator is working, the raw materials are evenly fed between the two rollers through the feeding system. As the roller rotates, the raw material is subjected to pressure from two directions. This pressure first flattens the raw material, and then as the roller rotates further, the raw material is pushed towards the edge of the roller, where it begins to bond into a ball due to the action of pressure and friction.

In order to form uniform particles, there is usually a certain gap between the rollers, which determines the final particle size. When the raw material mass reaches a sufficient size and density, it will detach from between the two rollers to form the desired particles.

The roller extrusion granulator can adjust the speed and clearance of the rollers to adapt to raw materials with different hardness and humidity, as well as produce particles of different specifications. In addition, in order to improve the granulation effect, the roller surface may have special textures or coatings to increase the grip on the raw materials and promote particle formation.

Throughout the process, the roller extrusion granulator can effectively convert raw materials into particles with a certain shape and size, while maintaining high production efficiency and product quality. Due to its simple working principle and easy to control operating characteristics, this equipment has been widely used in organic fertilizer production lines.

Now more and more investors have entered the organic fertilizer industry, but many users only have a simple understanding of the organic fertilizer industry and have no actual production. Therefore, there are still many problems in the process of investment.

So how much is the full set of organic fertilizer equipment? How to determine it? In fact, customers will find a lot of opinions about how much, because each customer’s situation is different, and there is no standard conclusion. For example, the annual output and production process of customer A and customer B are basically the same, but the raw material of customer A is dry chicken manure, and the raw material of customer B is wet chicken manure, then customer B must purchase a solid-liquid separator, and customer A does not. Then the price difference comes out. Therefore, the input of the organic fertilizer manufacturing process should be determined according to the actual situation.

A complete organic fertilizer manufacturing process includes machines: compost turning machine, crusher, fertilizer granulator, dryer, screening machine, automatic packaging machine, which are usually necessary for a complete organic fertilizer production line. In fact, there are different types and specifications of these equipment, such as fertilizer granulator, disc granulator, flat die pellet mill and new organic fertilizer granulator, and so are other fertilizer equipment. Of course, different specifications of machines, the price is different, so everything depends on the actual production needs of customers.

In summary, the annual output of 2000 tons to 10000 tons of organic fertilizer complete set of equipment how much? Specific still depends on the organic fertilizer manufacturing process. No matter it is manufacturing of NPK fertilizer, or livestock manure production of organic fertilizer project, welcome online consultation, can also come to the factory test machine at any time, we welcome your arrival at any time.

What kind of organic fertilizer turning machine is more suitable for handling viscous fertilizers

fertilizer granulator Jul 24, 2024

When dealing with viscous fertilizers, the selection of an organic fertilizer turning machine needs to consider the following key factors:

Material of the stacker:

Due to the strong corrosiveness and adhesiveness of viscous fertilizers, it is necessary to choose a turning machine made of corrosion-resistant and easy to clean materials, such as stainless steel or metal materials treated with special coatings.

Design of the flipping machine:

The design should avoid excessive adhesion of materials during the flipping process. For example, using a scraper or spiral flipping device instead of a traditional shovel flipping machine to reduce the contact area between the material and the flipping mechanism.

The working principle of the flipping machine:

Choose a machine that can achieve continuous and slow flipping, which can reduce material splashing and adhesion during the flipping process.

Heating system:

If possible, choose a compost turning machine equipped with a heating system, which can reduce the viscosity of fertilizers through heating and make them easier to turn over.

Auxiliary equipment:

Cooperate with the spray system to spray water regularly to reduce the viscosity of materials, which is conducive to the normal operation of the dumper.

Maintenance and Cleaning:

Choose a stacker that is easy to maintain and clean, in order to promptly remove materials adhering to the stacker and maintain the cleanliness and operational efficiency of the machine.

Operational flexibility:

Choose a turning machine that can adjust the turning parameters (such as turning depth, speed, etc.) according to the actual situation to meet the fertilizer processing needs of different viscosities.

Based on the above considerations, for the treatment of viscous fertilizers, it is recommended to choose a customized organic fertilizer turning machine, which should be designed with special consideration for the characteristics of the materials to ensure efficient and smooth turning process.

Why do organic fertilizer production lines use roller extrusion granulators

How to solve the vibration problem of fertilizer crusher in organic fertilizer production line

fertilizer granulator Jul 24, 2024

 In the organic fertilizer manufacturing process, if the organic fertilizer grinder encounters vibration problems, what should be done?

Organic fertilizer crusher generally uses a motor to directly connect the pulverizing device, which is simple and easy to maintain. However, if the two are not well connected during the assembly process, the overall vibration of the crusher will be caused.

(1) The motor rotor is not concentric with the pulverizer rotor. The position of the motor can be moved to the left and right, or a cushion can be added under the motor foot to adjust the concentricity of the two rotors.

(2) The crusher rotor is not concentric. The reason is that the two supporting surfaces of the rotor shaft are not in the same plane. The copper sheet can be padded on the bottom surface of the support bearing seat, or an adjustable wedge iron can be added at the bottom of the bearing to ensure that the two shaft heads are concentric.

(3) Part of the crushing chamber vibrates greatly. The reason is that the coupling between the coupling and the rotor is not concentric or the quality of the flat hammers inside the rotor is uneven. According to different types of couplings, corresponding methods can be adopted to adjust the connection between the coupling and the motor: when the quality of the hammers is uneven, each group of hammers must be re-selected to make the hammers symmetrical and the hammers symmetrical. The film error is less than 5g.

(4) The original balance is destroyed. After the motor is repaired, a dynamic balance test must be done to ensure the overall horse balance.

(5) The anchor bolts of the crusher system are loose or the foundation is not firm. During installation or maintenance, the anchor bolts should be evenly tightened. A shock-absorbing device should be installed between the foundation and the crusher to reduce vibration.

(6) The hammer piece is broken or there are hard sundries in the crushing chamber. All of these will cause unbalance of rotor rotation and vibration of the whole machine. Therefore, regular inspection should be carried out for the severely worn hammer pieces. When replacing, it should be replaced symmetrically; if there is abnormal sound in the operation of the pulverizer, it is necessary to stop the machine immediately for inspection, find out the reason and deal with it in time.

(7) The connection between crusher system and other equipment is not consistent. For example, improper connection of feed pipe and discharge pipe will cause vibration and noise. Therefore, the hard connection is not suitable for these connecting parts, but the soft connection is preferred.

The normal operation of the organic fertilizer crusher can ensure the uniform particle size of raw materials and make the processing of fertilizer granulator normal.

The specific process of using an organic fertilizer turning machine to produce organic fertilizer

fertilizer granulator Jul 19, 2024

The specific process of using an organic fertilizer turning machine to produce organic fertilizer usually includes the following steps:

Raw material preparation:

Firstly, collect and preprocess chicken manure to remove impurities and ensure the cleanliness and homogeneity of the raw materials.

According to the needs, it may be necessary to carry out pre-treatment processes such as crushing and screening of chicken manure to achieve suitable particle size and texture.

Raw material stacking:

Stack the prepared chicken manure evenly in the designated fermentation area.

When stacking, consideration should be given to the working space of the subsequent organic fertilizer turning machine to ensure that the shape of the pile is suitable for the working mode of the turning machine.

Set parameters:

Based on the characteristics and fermentation requirements of chicken manure, set the working parameters of the organic fertilizer turning machine, such as turning frequency, turning depth, etc.

The parameter settings should ensure that the flipping machine can effectively flip the stack while avoiding damage to the stack.

Start the stacker:

Start the organic fertilizer turning machine and let it start turning the chicken manure pile.

The flipping machine automatically completes the flipping action according to the preset parameters, evenly flipping the chicken manure to promote the fermentation process.

Fermentation process:

Under the action of the composting machine, chicken manure undergoes aerobic fermentation, and microorganisms decompose the organic matter in the manure, producing heat and carbon dioxide.

During the fermentation process, the temperature gradually increases to reach the temperature range suitable for microbial activity, usually between 50-70 degrees Celsius.

Monitoring and adjustment:

During the fermentation process, it is necessary to regularly monitor key parameters such as temperature and humidity of the heap to ensure the normal progress of the fermentation process.

According to the monitoring results, adjust the parameters of the flipping machine in a timely manner, such as increasing the flipping frequency, to maintain the appropriate state of the pile.

Mature judgment:

When the temperature of the chicken manure pile begins to decrease and remains stable for a period of time, it indicates that the fermentation process is nearing its end and the organic fertilizer has basically matured.

At this point, the turning machine can be stopped to allow the organic fertilizer to cool naturally and ripen.

Post ripening and sieving:

Let the organic fertilizer continue to ripen in the heap for a period of time to further stabilize its quality.

After the post ripening process, use a screening machine to screen the organic fertilizer, remove large chunks of incompletely decomposed material, and obtain qualified organic fertilizer products.

Packaging and Storage:

Pack the screened organic fertilizer and store it in a dry and ventilated warehouse, waiting for sale or use.

Equipment maintenance:

After each turning operation, clean and maintain the organic fertilizer turning machine to ensure its normal operation and service life.

Through the above process, the organic fertilizer turning machine can efficiently produce high-quality organic fertilizer, providing a high-quality source of organic fertilizer for agricultural production.

The specific fermentation process of organic fertilizer turning machine for processing fertilizers

fertilizer granulator Jul 19, 2024

The workflow of an organic fertilizer turning machine usually follows the following steps:

Raw material deployment:

Evenly lay the prepared organic materials, such as livestock manure, crop straw, etc., in the fermentation bed or composting field.

The laying thickness of raw materials is usually determined based on the type of material and fermentation requirements.

Start the stacker:

According to the needs of the fermentation process, set the working parameters of the organic fertilizer turning machine, such as turning frequency, turning depth, etc.

Start the flipping machine to begin flipping the pile.

Pile flipping homework:

The organic fertilizer turning machine uses its rotating turning shovel or rake teeth to turn the materials in the pile up and down, achieving material mixing and ventilation.

This process helps to increase the oxygen concentration inside the reactor, promoting the growth and metabolic activity of microorganisms.

Adjust temperature and humidity:

During the flipping process, the temperature and humidity of the pile can be adjusted by controlling the flipping frequency and depth to maintain optimal fermentation conditions.

For certain specific fermentation processes, such as aerobic fermentation or anaerobic fermentation, special temperature or humidity control measures may be required.

Fermentation process:

After a period of flipping, organic materials undergo biodegradation reactions, generating heat and promoting microbial activity.

As fermentation progresses, the temperature of the heap will rise and gradually decrease after reaching a certain peak, which is a sign of vigorous microbial activity.

Mature stage:

When the temperature of the heap begins to steadily decrease and reaches a lower level, it indicates that the fermentation process is nearing completion and the organic materials have entered the mature stage.

At this stage, microbial activity slows down, organic matter further decomposes, and stable organic fertilizers are formed.

Subsequent processing:

Mature organic fertilizers can undergo subsequent treatments such as screening, crushing, and drying to meet different usage requirements.

The processed organic fertilizer can be used for fertilizing farmland, improving soil structure, and providing the nutrients needed by plants.

Equipment maintenance:

After each flipping operation, clean and maintain the organic fertilizer flipping machine to ensure its normal operation and extend its service life.

Through the above workflow, the organic fertilizer turning machine can efficiently process organic materials, produce high-quality organic fertilizers, reduce environmental pollution, and promote sustainable agricultural development.

How to ensure the quality of organic fertilizers produced by fertilizer production lines

fertilizer granulator Jul 19, 2024

 With the rapid development of agriculture, crops and fertilizers are inseparable, and organic fertilizer is an indispensable fertilizer in agricultural development. The raw materials of the organic fertilizer manufacturing process are agricultural straw waste and livestock waste. The crushed straw and livestock manure are mixed with each other, and after high-temperature fermentation and decomposing, they are processed into commercial fertilizer through organic fertilizer production line equipment.

Organic fertilizer is rich in nutrients, but there are also unqualified fertilizers mixed into it, such as too much raw material, too long crushed straw, etc. As a manufacturer of NPK fertilizer manufacturing process and organic fertilizer production process equipment, we introduce the following methods to identify fertilizer quality:

1) Take a water cup with bubble method, soak the organic fertilizer sample in water, then crush the organic fertilizer soaked in water by hand, mix the raw material of organic fertilizer intuitively, and place it for a period of time. If the organic fertilizer and water are stratified in a short time, it means that the proportion of organic fertilizer is large and the soil is more.

(2) Hand twisting method uses organic fertilizer as raw material and rolls back and forth with thumb and index finger. If there is feeling of hand injury, there will be sand or other impurities.

3) Smell the smell of the fertilizer carefully to see if there is ammonia, manure or silt smell. The decomposed organic fertilizer should be a mature smell after being regularly thrown by the compost turning machine.

4) After selecting organic fertilizer, some organic fertilizer was not applied to crops, and the performance of the plant was observed. Good organic fertilizer had obvious influence on the growth, yield and quality of the plant.

5) Check whether the packaging meets the specifications and whether it is approved for production (generally approved production does not have its own factory and has no source of raw materials).

6) The organic fertilizer machine manufacturer pointed out that using the strain test method, take a water cup and put the organic fertilizer into it, sprinkle a little water (be careful not to soak the water, wet the line), and place it in a warm and suitable place. A good organic fertilizer will Take the head out of the white Pythium, the broken organic fertilizer particles will also see white mycelium inside.
