The role of roller extrusion granulator in the fermentation and granulation of cow manure

fertilizer granulator Sep 6, 2023

The application scope of the cow manure fermentation granulation production equipment to the roller extrusion granulation machine: it is suitable for various ratios of organic compound fertilizers, bio organic fertilizers, urban sludge, household waste organic fertilizers, etc. It fills the domestic gap and ranks at the leading level in China. It is a promotion project of national environmental protection practical technology, and chicken manure is rich in organic matter, which can provide the nutrients required for crop growth and improve soil fertility. There are various types of organic fertilizers, with a wide range of raw materials and ever-changing fertilizers.

The working principle of the roller extrusion granulator: Dry materials aggregate under pressure to form dense and hard large blocks (cakes), which is called the extrusion process; The process of crushing and screening the cake material into granules is called granulation.

The function of the roller squeezing granulator is to expel the air between the particles, and to make the distance between the particles close enough to generate attractive forces such as van der Waals force, adsorption force, crystal bridge, and embedded connection. The particle strength formed by squeezing granulation mainly relies on the force between molecules.

Price advantage of roller extrusion granulator:

1. Energy saving and consumption reducing extrusion granulation refers to the granulation of materials at room temperature, which does not require drying measures such as fuel and gas compared to other methods.

2. The commonly used production method for compound fertilizers in China without the need for additional adhesives is steam granulation. After condensation and crystallization between material molecules, water vapor acts as a binder during the manufacturing process. But during the drying process, the water inside and on the surface of the particles must be expelled, otherwise the fertilizer is prone to sticking and caking during storage. And dry granulation does not require additional additives, only utilizes the intermolecular forces of the material itself, simplifying the process and reducing energy consumption.

3. Low investment due to the elimination of the drying process and low return ratio (accounting for about 15% of the total feed volume of the extruder), the process flow is simple and the investment is low.

4. The flexible composition of raw materials for extrusion granulation production has a wide range of raw material routes. Currently, more than 20 types of materials have been successfully used for extrusion granulation, such as urea, ammonium chloride, calcium nitrate, potassium sulfate, etc. In addition, the use of extrusion granulation technology can flexibly achieve product formula replacement in a very short time, and a set of devices can produce more than 30 formula products.

5. Green environmental protection has no emissions of three wastes, and the ability to consume through extrusion granulation is only for electricity. Environmental protection has no emissions of three wastes, which is in line with the basic national policies on environmental protection and the development strategy of enterprise environmental protection.

Benefits of processing granular fertilizers on fertilizer production lines

fertilizer granulator Sep 6, 2023

There are mainly two types of organic fertilizers, powdered fertilizers and granular fertilizers. Among them, there are more granular fertilizers in daily processing. The main purpose of organic fertilizer production equipment to manufacture granular organic fertilizer is to facilitate bagged transportation and prevent secondary fermentation of organic fertilizer. In addition, granular organic fertilizers are selling well.

The organic fertilizer granule production line is mainly composed of eight parts: quantitative conveying, crushing, screening, granulating, drying, cooling, finished product screening, and packaging. Commonly used organic fertilizer granulation equipment includes: disc granulator machine, drum granulator, wet granulator, npk fertilizer granulator, flat die granulator, and ring membrane granulator. The pig manure processing organic fertilizer granule production line is mainly composed of eight major parts: quantitative conveying, crushing, screening, drum granulation, drying, cooling, finished product screening, and packaging. The configuration of small pig manure organic fertilizer equipment only needs pulverizer, mixer, organic fertilizer granulator machine, screening machine and packaging machine to complete the production.

Let’s explain why organic fertilizer production equipment is processed into granules:

1. It is more convenient to apply. Some organic fertilizers have a relatively light specific gravity, which is easy to be blown away by the wind when applied, and it is easy to apply when made into granules.

2. If you add inorganic ingredients, you can add some inorganic ingredients to the fertilizer to improve the fertilizer efficiency, if you add inorganic ingredients, it can easily absorb water and agglomerate.

3. In order to obtain powder, the material must be dehydrated and crushed. The biggest limiting factor in organic fertilizer production is that moisture cannot be removed and needs to be dried. Do not dry when making granules. High heat is generated during the granulation process, and it only needs to be cooled, which is very convenient.

Equipment configuration for making fertilizer on the organic fertilizer production line of cow and sheep manure

fertilizer granulator Sep 6, 2023

The livestock and poultry breeding industry has developed rapidly, with the characteristics of regionalization, scale, and intensive management. Animal husbandry has made significant contributions to the improvement of people’s living standards, but it has also caused serious environmental pollution, hindering the sustainable and stable development of the animal husbandry industry. Animal manure is rich in organic matter and a certain amount of nutrients such as nitrogen, phosphorus, and potassium, making it a good source of organic fertilizer. If livestock manure is not treated and directly discharged into the environment, it not only pollutes the environment, spreads diseases, but also causes waste of resources. Therefore, it is very important to harmless and resource treat livestock and poultry manure.

If it is a traditional rural fertilizer making method, organic fertilizer can be composted without any mechanical equipment, but the composting cycle is too long. The production of simple powdered cow and sheep manure organic fertilizer can be achieved with only one composting machine and grinder.

How to configure the organic fertilizer production line using cow and sheep manure? How much is the equipment for producing organic fertilizer from cow and sheep manure?

1. The simple configurations for producing granular organic fertilizers include a crusher, mixer, granulator, screening machine, and packaging machine.

2. The complete set of cow and sheep manure organic fertilizer equipment includes: composting machine, grinder, mixer, granulator, dryer, cooler, screening machine, coating machine, and packaging machine.

The traditional composting method is definitely being phased out now. The simple production mode of powdered organic fertilizer is suitable for self use. If you have a large amount of farmland or orchard tea gardens, this production mode is recommended. After the fermentation of organic fertilizers is completed, granulation treatment is also required. The commonly used granulation techniques include the agglomeration method and the extrusion method. The former is carried out in a granulation machine, where the raw materials need to be stirred evenly in a mixer according to a certain formula, and then transported to the granulation machine for granulation. After that, a series of treatments such as drying, screening, cooling, returning, wrapping, and tail gas purification are carried out to finally obtain the organic fertilizer product. The production capacity of the pellet method is high, and the fertilizer particles produced have the advantages of smooth appearance and uniform particle size.

The products produced by simple configuration of granular organic fertilizers can be sold, but the price is not high, suitable for small-scale sales. This type of production line configuration is suitable for enterprises that do not have sufficient funds in the early stage but want large-scale production, and other equipment can be supplemented later.

Equipment principle and process of sheep manure organic fertilizer crusher

fertilizer granulator Sep 6, 2023

The raw materials in sheep manure organic fertilizer equipment are often diverse, so it is very important to handle the raw materials well, and crushing equipment is one of the commonly used equipment. Moreover, in order to achieve uniform fermentation and granulation of raw materials, organic fertilizer crushers must be used. Organic fertilizer crushers can crush materials into fine particles and are suitable for crushing various materials. Organic fertilizer crushers are also indispensable equipment in organic fertilizer production lines.

What is the area of sheep manure organic fertilizer equipment? How large does the factory need?

The use of an organic fertilizer crusher mainly involves rough crushing of raw materials in preparation for secondary crushing. Organic fertilizer crusher is suitable for crushing hard or medium hardness raw materials. It is not suitable for crushing soft and hard raw materials, and the moisture content of the materials should not be greater than 10%. If the moisture content of the raw materials is too high, it is easy for the material to grow on the jaw plate, which affects the crushing efficiency. It is particularly worth mentioning that when using an organic fertilizer crusher, two points should be noted:

1. Before the material enters the crushing equipment, the powder particles in the material should be screened out in advance, which is of great significance for the utilization efficiency of the capacity of the organic fertilizer crusher. This is because these powder particles can fill the slots between the jawboards, reducing the effective height of the edges, so that the material between the jawboards is crushed only by pressure.

2. It should be noted that the feeding of materials to the crushing equipment should be ensured to be applied along the entire width of the feeding port as much as possible, ensuring uniform feeding. If necessary, special feeders can be used.

The processing technology of sheep manure organic fertilizer equipment is advanced, with a compact structure. Harmless live bacterial preparations are used to treat livestock and poultry manure, and biological fermentation is carried out under the action of various beneficial microorganisms. After fully decomposing the organic matter, nutrients are released, and the resulting biological heat and high-temperature fermentation process can kill insect eggs and bacteria, purify the environment, detoxify and deodorize, achieving resource utilization and industrialization, low energy consumption, harmless treatment, and stable product quality.

In the process of raw material blending, the organic fertilizer composting machine plays a stirring role, which can effectively blend various raw materials together, thus enabling full integration of raw materials. 2. The organic fertilizer composting machine can adjust the temperature by continuously stirring during daily production, allowing the raw materials to come into full contact with the air and allowing for more complete fermentation.

3. The organic fertilizer composting machine can change the permeability of the raw materials during the mixing process, thereby greatly improving the nutrition of the raw materials. In the process of organic fertilizer production, the trough composting machine plays a role in fermentation, ventilation, and oxygen supply throughout the entire production process, and is one of the necessary equipment for the entire fermentation process.

The characteristics of hydraulic trough type organic fertilizer tipping machine include three points:

1. The hydraulic trough tipping machine can reach a stacking span of 4-12 meters and a fermentation cycle of about 15 days. The length of the fermentation tank depends on the situation. It is possible to feed at the inlet every day and discharge at the other end. Feed and process daily. When the flipping machine needs to change the flipping section after flipping, the stirring dragon can be raised to quickly run the equipment to the flipping section.

2. The hydraulic trough type tipping machine has a compact structure, advanced technology, and the use of some beneficial microorganisms can promote the rapid decomposition of organic waste such as livestock manure. Adopting a unique tank type continuous aerobic fermentation technology, organic waste is quickly decomposed, dehydrated, sterilized, and deodorized, achieving the goal of harmless, resourceful, and reduced treatment, with low energy consumption and stable product quality.

3. The intelligent automatic control of the fermentation material turnover process, under the action of vertical and horizontal walking mechanisms, causes a certain turnover displacement of the fermentation material in the pool, and the material moves back in a continuous and equal distance gradually in the pool, thus forming a continuous and itchy fermentation process. The stirring knife not only flips evenly and oxygenates, but also has the function of crushing materials.

How to produce granular fertilizer using a wet organic fertilizer granulator

fertilizer granulator Sep 2, 2023

Common wet organic fertilizer granulators include: rotary drum granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, ring die granulator Machines, various granulators have their own production characteristics, and the fertilizer granulator machine price vary.

1. Prepare

You need to ferment, pulverize and blend the organic material before pelleting. Inorganic materials are simply ground and mixed into a powder. Huaqiang Heavy Industry provides you with high-quality compost machines, fertilizer crushers and fertilizer mixers to do these jobs.

2. Wetting process

Add just the right amount of binder to help with clumping, you can also call this process wetting. You can spray the adhesive solution into the machine, or add the liquid as a foam. The type of binder solution varies depending on the raw material. It can be roughly divided into two types, aqueous solution or organic solvent. Aqueous solutions are cheap and safe, but take longer to dry. Organic solvents are volatile and suitable for moisture-sensitive materials. But they are more expensive and not good for the environment. Wet granulators use steam and steam to wet the material, they are cheap and environmentally friendly.

3. Granulation

After the raw material gets wet and some chemical reactions happen, the powder starts to roll with the organic fertilizer granulator machine. Under the combined action of centrifugal force and inter-particle compaction, the material gradually forms the particles we want.

4. Drying process

The granulated product still has a lot of moisture after granulation. For easy portability or storage, you’ll need to dry them out. That’s when a tumble dryer is needed to get the job done quickly. It will dry the granules evenly.

5. Cooling process

It is not good for fertilizer granules to be exposed to high temperature and dry for too long. So you need a drum cooler to preserve the nutrients and actives in the granules. Our chillers do the job quickly and reliably.
