Benefits of organic fertilizer processed by sheep manure organic fertilizer production line to land and crop production?

1. Wide adaptability

Sheep manure organic fertilizer is suitable for sandy soil and cohesive soil. It can be applied to various crops and can increase production, quality and efficiency.

2. Protect the rhizomes of crops and provide them with comprehensive nutrition

Sheep manure organic fertilizer contains a lot of nutrients, trace elements, sugars and fats needed by plants. The CO2 released from the decomposition of sheep manure organic fertilizer can be used as a material for plant photosynthesis. Sheep manure organic fertilizer also contains 6-8% nitrogen, phosphorus, and potassium, and 50-55% organic matter, which can provide comprehensive nutrition for crops.

 3. Improve soil quality and promote the reproduction of soil microorganisms

The microorganisms in sheep manure organic fertilizer multiply very quickly in the soil, leaving many thin tubes in the soil, which not only increases the permeability of the soil, but also makes the soil fluffy and soft, and nutrients and water are not easily lost, thereby increasing the soil’s water and fertilizer storage. Ability to avoid and eliminate soil compaction. The beneficial microorganisms in sheep manure organic fertilizer can also inhibit the reproduction of harmful bacteria, so that pesticides can be used less.

4. Enhance crop resistance to disease, drought, and waterlogging tolerance

Because sheep manure organic fertilizer contains vitamins and natural antibiotics. It can enhance crop resistance and reduce or prevent disease.

 5. Increase crop yield

The beneficial microorganisms in sheep manure organic fertilizer use the organic matter in the soil to produce secondary metabolites, which contain a lot of growth-promoting substances.

The sheep manure is pulled to the organic fertilizer production plant, and the organic fertilizer manufacturing equipment is used to make it fermented to achieve harmless treatment. After being decomposed, it is crushed, sieved, granulated and packaged into organic fertilizer. After that, organic fertilizers are classified, processed, packaged into different specifications for different types of fertilizers, such as field crops, orchard vegetable bases, landscaping, and home gardening, and then sold.

The production and processing of organic fertilizer are generally divided into powder processing and granular granulation. The general raw materials of organic fertilizer are animal manure, crop straw, sludge and biogas residue, etc. The manure of livestock and poultry is fermented, the middle part is tossed by the compost dumper, crushed by the high humidity material grinder, and then screened by the screening machine. The screened product is powdered organic fertilizer. The unqualified products are crushed again, and the qualified powdered organic fertilizer can be packaged directly. Powdered organic fertilizer is welcomed by the growers because of its low price and long-term fertilizer effect. And the granular organic fertilizer must be processed again by equipment such as fertilizer granulator machine. Generally, the materials are fermented and crushed before passing through screening machine, dryer and cooler, and then coated for granulation. The product value is higher and the profit space is large.
Organic fertilizer production and processing

1. Ground composting (use crawler turning machine), or feed material in fermentation tank (use trough compost turning machine).

2. Sprinkle the fungicide evenly, turn over the fermentation to increase the temperature, stink, rot, and kill the mixed fungus seeds.

3. Fermentation for 15-20 days, how many times the piles are turned according to different temperatures in different places.

4. Completely fermented and rotted out of the pond (ground type directly piled up with a forklift).

5. Use a sieving machine to screen the thickness. (The selected powdered fertilizer can be sold directly).

6. Crush the screened large pieces with a grinder and return to the screening machine.

7. Mix the required trace elements with a premixer.

8. Granulate with an organic fertilizer granulator. We also provide flat die pellet mill, disc fertilizer granulator and many other granulation equipment.

9. Feed into dryer and cooler.

10. Automatic packaging machine packaging and sale.

In fact, the organic content of granular organic fertilizer is not as much as that of powder. In the drying process of granular organic fertilizer, due to the control of high temperature, it may kill the organic matter required by the soil. Although the nutritional composition of granular organic fertilizer is more comprehensive, when the soil has a large demand for organic matter and needs to improve the soil structure, you can choose an inexpensive powdered organic fertilizer.

The NPK (nitrogen phosphorus potassium compound) fertilizer production line uses a roller extrusion granulator to produce fertilizers, which is a complex and precise industrial process involving multiple steps such as raw material preparation, mixing, extrusion, molding, and post-processing. Below is a detailed introduction to this process:

1. Raw material preparation

Firstly, collect all necessary raw materials, including nitrogen fertilizers (urea, ammonia, etc.), phosphorus fertilizers (monoammonium phosphate, diammonium phosphate, etc.), potassium fertilizers (potassium sulfate, potassium chloride, etc.), as well as any other trace elements or fillers that may be added. These raw materials must be accurately measured in proportion.

2. Mixing and preprocessing

Feed the weighed raw materials into the mixer for thorough mixing, ensuring that all components are evenly distributed. During the mixing process, it may be necessary to add appropriate moisture or other liquid additives for subsequent extrusion molding.

3. Extrusion granulation

The mixed raw materials are transported to the feeding inlet of the roller extrusion granulator. A roller granulator consists of two or more roller shafts that rotate relative to each other, with a certain gap in between. When the raw material passes through this gap, it is compressed under strong pressure and extruded into long strips or sheet-like objects through the mold holes, and then immediately cut into particles of the desired length by the cutter.

4. Cooling and solidification

The fertilizer particles just extruded from the roller are in a high temperature state and need to be cooled to prevent deformation or melting. Send the particles through a conveyor belt into a cooling tower or air cooling device to gradually cool them down to around room temperature and accelerate the solidification process.

5. Hierarchical screening

The cooled particles enter the screening machine and are classified according to particle size. Particles that do not meet the size standards will be re crushed and returned to the previous process for granulation until they meet the set standards.

6. Encapsulation treatment (optional)

In order to improve the appearance quality and moisture and corrosion resistance of fertilizers, some production lines will also add a coating step after granulation. Coating a thin protective layer on the surface of the particles can not only beautify the appearance but also extend the shelf life.

7. Packaging and Storage

Finally, qualified fertilizer particles are weighed, bagged, and sealed to complete the finished product packaging. The packaged fertilizer bags are sent to the warehouse for storage, waiting for distribution and sale.

In the entire production process, the roller extrusion granulator is the core link, and its performance directly affects the quality, strength, and uniformity of the particles. A well-designed production line should balance efficiency and quality, ensuring that each batch of fertilizer meets high industry standards. Through continuous technological innovation and optimization, the NPK fertilizer production line continuously improves production capacity and product competitiveness, serving the needs of global agricultural development.

 The use of organic fertilizer when growing vegetables and fruits can make vegetables and fruits grow better, so organic fertilizer manufacturing equipment is required. However, the use of organic fertilizer equipment is more troublesome, and certain technical requirements are required to operate the organic fertilizer equipment correctly. .So, what are the basic operating requirements for organic fertilizer equipment?

Process characteristics of organic fertilizer made from animal manure

1. In terms of time, it is basically not affected by the season, and the scale of equipment investment is small, and the plant area occupied by the equipment is small. In the actual use process, the operation is simple and the management and maintenance costs are very low.

2. Poultry manure will be fermented after being professionally processed by the equipment, the related bacteria will be eliminated, and the odor will be removed to produce organic fertilizer.

3. It can make full use of poultry manure and realize the increase of the by-product benefit of poultry and livestock breeding industry.

4. Poultry manure can be processed relatively quickly, reducing the time of accumulation in the open air, and reducing pollution to the greatest extent. Second, the technical key to the production of organic fertilizer equipment from livestock manure.

In the livestock and poultry manure making organic fertilizer equipments required for biofertilizer production, the core critical equipment is the stacker. The materials and the composition of the main parts have a very important impact on the processing of poultry manure. Generally speaking, the relevant parts must have Good characteristics such as corrosion resistance and acid resistance, because most livestock manures are corrosive, therefore, improving the corrosion resistance of the equipment is the key to prolonging the service life of the equipment.

1. The quality of the organic fertilizer is importantly affected by the material ratio parameters, which requires technical management personnel. When setting the relevant material ratio parameters, the actual air temperature, humidity, etc.

2. Scientifically control the water content and reasonably control the temperature of the material.

3. Stable electrical and electrical control operation system.

Chicken manure organic fertilizer equipment requires two steps to process commercial organic fertilizer: the pre-fermentation and treatment part and the deep processing granulation part. The bio-organic fertilizer equipment requires a fermentation turning machine, an organic fertilizer grinder, a drum screening machine, and a horizontal mixer. , organic fertilizer granulator(drum granulation), rotary dryer, cooler, coating machine, packaging machine, conveyor and other equipment.

 The farms produce a large amount of manure every day. These manures are inexpensive, and a large amount of manure can be made into organic fertilizer products through organic fertilizer production equipment. Fermentation of organic fertilizer by organic fertilizer production equipment can greatly improve the economic benefits of aquaculture, at the same time, it can effectively reduce pollution and purify the environment. Organic fertilizer is a kind of high quality fertilizer, which can greatly improve crop yield and quality. Soil organic matter is the basis of soil fertility, which directly affects soil fertility, water retention, buffering and aeration. Organic matter can be decomposed by microorganisms to form humic acid, which can make loose soil form soil aggregates, make soil bulk density smaller, porosity increase, easy to absorb water infiltrated into soil and nutrient ions released, and make effective nutrient elements not easy to be fixed. Organic fertilizer plays an important role in agricultural crops. Organic fertilizer production equipment has good benefits in processing organic fertilizer.

Compost turning machine

Composting fermentation is the first step in the process of organic fertilizer by organic fertilizer production equipment. Composting fermentation removes harmful substances from fermentation products such as feces and produces humus beneficial to soil. In organic fertilizer production and fermentation, the control of water, temperature, air and other conditions has an important impact on the quality of organic fertilizer. We use organic fertilizer production equipment to treat composting materials, provide suitable environment for organic fertilizer production, and ensure the quality of composting.

The compost turning machine realizes the high-yield treatment of organic fertilizer fermentation. The compost  turning machine is used in the fermentation tank environment. It provides sufficient oxygen for the material through mechanical turning, while stirring the material to make the material mix evenly.

Roll extrusion granulator and drum granulator are commonly used granulation equipment, each with its own unique granulation mechanism and application scenarios. The main differences between the two are as follows:

The granulation principle is different

Roll squeezing granulator: Based on the principle of pressure granulation, powder or sheet materials are extruded into continuous strips under high pressure by one or more pairs of rotating rollers in opposite directions, and then cut into particles of the desired particle size. This process is similar to “pressing a cake and cutting it into pieces”.

Drum granulator: utilizing the rolling and stirring effect inside a rotating cylindrical container, adding an appropriate amount of liquid binder to aggregate the material and gradually increase it on the container wall to form spherical particles. This is a dynamic granulation process, similar to a ‘snowball rolling’.

Applicable material types

Roll extrusion granulator: suitable for dry or plastic materials, especially those that can be formed by extrusion, such as mineral powder, chemicals, and some fertilizers.

Drum granulator: more suitable for materials with strong viscosity and good fluidity, such as some organic fertilizers, drugs, and food additives.

Finished product features

Roll granulation: The produced particles have high uniformity, regular shape, and high particle strength, but the shape is relatively flat.

Drum granulation: The produced particles have a more rounded shape and beautiful appearance, but due to the rolling process, there may be some differences in particle size.

Equipment construction

Roller squeezing granulator: The structure is relatively compact, the footprint is small, and the installation and debugging are relatively simple.

Drum granulator: The equipment has a large volume and consists of one or more rotating cylindrical bodies, used for containing and rolling materials.

Energy consumption and cost

Roller squeezing granulator: Due to its granulation process not relying on external heat sources, its energy consumption is relatively low.

Drum granulator: Additional heat or liquid additives may be required, resulting in slightly higher energy consumption and initial preparation costs.

Application scenarios

Roll squeezing granulator: widely used in chemical, fertilizer manufacturing, building materials and other fields, especially in the granulation of hard materials.

Drum granulator: It is widely used in the food processing, pharmaceutical, feed, and fine chemical industries, and is particularly suitable for producing substances that are easy to agglomerate.

Maintenance and operation

Roller squeezing granulator: maintenance is relatively simple, mainly cleaning and lubrication.

Drum granulator: More cleaning and maintenance work may be required, especially to keep the inner wall of the drum clean to prevent material accumulation.

Overall, both roller extrusion granulators and drum granulators have their own advantages and disadvantages. The choice of granulation method should be determined based on specific production needs, material properties, and expected particle characteristics. In practical applications, it is sometimes necessary to combine the advantages of these two methods, such as first extruding the initial shape with a pair of rollers, and then polishing and shaping it with a rotary drum to achieve the desired granulation effect.

Regarding the daily maintenance methods of the fertilizer manufacturing equipment turning and polishing machine, let’s let the turning and polishing machine manufacturers give you a good talk:
Warranty card rules and regulations: The whole machine is guaranteed for half a year from the date of sale. During the warranty period, the following items are not included in the scope of the three guarantees
1. Not used in accordance with the instructions, artificial damage
2. The turning blade is worn and broken
3. The motor burns when water enters. The carbon brush is worn out.
Track-type compost turning machine is currently the most extensive fermentation turning application equipment, including walking wheels, side wheels, and computer control devices, turning parts (also called shifting vehicles, mainly used for double trough or the use of more than double slot). The trackless stacker is driven by rollers, and the width and inner diameter of the groove can be customized according to the user’s different breeding capacity (3-10 meters). When the depth of the turning harrow is not more than 1.3 meters, the wall height is less than 2 meters. The rake turning device is connected with the travel switch through the main shaft. The automatic rake turning machine is suitable for aerobic fermentation, solar fermentation room, fermentation tank and shift car spray equipment, etc. The supporting fermentation tank can continuously discharge materials in batches. The turning and polishing machine has high efficiency, stable operation, sturdiness and durability, low maintenance cost, and simple and convenient remote control operation.

Science and technology are the primary productive forces. With the development of science and technology, the aquaculture industry is constantly developing and changing. We all know that the litter is an important step that needs to be maintained and loosened. After two months of production, it needs to be turned almost every day, otherwise it will cause the fermentation bed to die, causing the feces to be unable to decompose, the fermentation bed to be wet, insects, and frequent diseases. When things happen, the farming technology that can save labor has increased labor. The traditional method is to use manpower to turn the rake with a nail rake. It takes more than an hour for one person to turn all the 20 square meters of litter area at a time, which is laborious and time-consuming and the effect is not ideal. The depth of digging and climbing is generally only 10- 15 cm, the litter cannot be completely broken, the agglomeration cannot be completely scattered, and the real loosening effect cannot be achieved, so the time interval for the next turning rake is relatively short, and the quality of the litter loosening effect directly Decomposing performance of feces to the fermentation bed.

Sheep manure organic fertilizer production line equipment manufacturers are mainly to produce organic fertilizer production machine, organic fertilizer granulator machine, organic fertilizer tipper, organic fertilizer mixer, organic fertilizer screening machine, organic fertilizer drying and cooling machine, organic fertilizer coating packaging machine and other complete sets of organic fertilizer equipment production line, integrating scientific research, production, sales, providing process design, installation, commissioning and personnel training for customers The price comparison of the simple fermentation process of sheep manure was made by the manufacturers.

After stacking, fermentation and turning, the moisture content is reduced to 35-50%. At this time, the sheep manure, also known as fermented sheep manure, is crushed, screened and bagged, and the price is between 150-200 tons / yuan.

Natural fermentation of sheep dung (after secondary fermentation of the stacked sheep manure, turning over the pile for the second time, drying, the moisture content of the fermented sheep manure can be reduced to less than 30%). After bagging, the price of sheep manure produced in this way is 200-300 yuan / ton.

Sheep manure organic fertilizer production line — referring to the natural fermentation method, the organic fertilizer complete equipment is used for one-time fermentation, and the fermentation biological bacteria are added into the fermentation machine. After 7-10 days of composting, and then 10-15 days after the second turning, the fermented sheep manure has no peculiar smell, and probiotics bacteria are added to make the beneficial biological bacteria rapidly propagate in the fermented sheep manure. In this way, after about a month, the beneficial biological bacteria continue to grow and die in the process of reproduction. The dead biological bacteria is the cell protein, and the growing live bacteria are still growing. Through the processing of organic fertilizer equipment production line, such fermented sheep manure has reached the national standard of biological organic fertilizer, which is used in agricultural production, and the effect is several times more than that of natural fermentation sheep manure. The price of packaged compost is higher than that of ordinary compost, and the nutrition is balanced.

When choosing to produce NPK (nitrogen phosphorus potassium compound) fertilizers, whether to use a roller extrusion granulator or a rotary drum granulator depends on various factors, including production scale, raw material properties, cost considerations, and expected product quality. Here is a comparative analysis of two granulation technologies to help you make a more suitable choice:

Advantages of Roll Extrusion Granulator

High particle strength: The particles produced by the roller extrusion granulation mechanism have high hardness and are not easily broken, making them suitable for long-distance transportation and storage.

Flexible operation: Suitable for handling various types of raw materials, including fine powders or materials containing a certain amount of moisture.

Low energy consumption: Compared with drum granulation, roller granulation generally requires less energy input, reducing operating costs.

Small footprint: Compact structure, occupying less space, suitable for factory layouts with limited space.

Good uniformity of finished products: high consistency in granulation size, which is conducive to the uniformity of subsequent packaging and fertilization.

Characteristics of rotary drum granulator

Wide applicability: Suitable for handling materials with strong viscosity, and may have advantages for some raw materials that are difficult to shape by extrusion.

Large capacity production: The rotary drum granulator is suitable for large-scale industrial production and has a large one-time processing capacity.

The finished product is round and beautiful: it is formed by naturally rolling the particles through rotation, with smooth edges and excellent appearance texture.

Strong adjustability: By adjusting factors such as drum speed and tilt angle, particle size and shape can be controlled.

How to choose

Raw material characteristics: If the raw material is delicate or contains a certain amount of moisture, a roller granulator may be a better choice; For situations with strong viscosity and high production requirements, consider using a rotary drum granulator.

Cost budget: Initial investment and operating costs are also important factors, and it is necessary to comprehensively compare the prices, maintenance costs, and energy consumption differences between the two models.

Product requirements: Considering the physical properties of the final product (such as particle strength, shape) and market demand, choose the most suitable granulation method.

Environmental conditions: For small enterprises with limited space, the advantage of occupying space for roller extrusion granulators is obvious; Large manufacturers pursuing mass production may be more inclined towards drum granulators.

In short, each granulation method has its own unique features, and the ideal choice is the one that can best match your specific production needs and conditions. Field visits and consulting with professionals’ opinions can also greatly benefit the decision-making process.
