The new fertilizer production line project should comprehensively consider the local resources, market capacity and market coverage radius. Generally, the annual output of small-scale new plants is 10000 tons (1.5 tons / hour), 20000 tons (3 tons / hour) and 30000 tons (4.5 tons / hour). The annual output of medium-sized factories is 50000-100000 tons, and that of large-scale factories is 100000-300000 tons.

The investment scale and scheme design need to be formulated according to the following conditions: characteristics of raw material resources, local soil conditions, local planting structure and main crop varieties, plant site conditions, selection of NPK fertilizer granulator, production automation degree, etc.

Several equipments of fertilizer production line

1. Mixer. In addition to chemical fertilizer raw materials, some sticky materials such as clay can be properly added during mixing. During operation, the materials are evenly mixed by stirring back and forth with multi-channel rotating blades.

2. Fertilizer granulator. Small scale production generally uses organic fertilizer granulator to meet the requirements.

3. The rotary dryer is mainly composed of drying cylinder, transmission device, supporting device, head and tail sealing parts. The diameter ranges from 80 cm to 3 m, and the length depends on the drying requirements. The dryer is a cylinder inclined to a certain angle with the horizontal direction. The material is added from the higher end, and the high-temperature flue gas and the material enter into the cylinder in parallel. With the rotation of the cylinder, the material moves to the lower end due to gravity. A lifting plate is welded on the inner wall of the cylinder to take up and drop the materials, and fully contact with hot air in the falling process, so as to achieve the purpose of drying.

4. The rotary cooler can reduce the moisture content while cooling a certain temperature. It is the same equipment as the dryer, except that the air is drawn from the head to the outside when used, so there is no need to seal the tail.

5. The drum screening machine adopts a combined screen, which is convenient for maintenance and replacement. The machine has a simple structure, convenient operation and stable operation.

Fruit pomace is the remaining fruit pomace after the water content of the fruit is extracted from the food, such as apple pomace, tomato pomace, pear, corn, grain, sugarcane, medicinal pomace, and other different types of pomace. Due to the economic added value of secondary processing benefits such as feed, the dried fruit pomace contains a certain amount of internal moisture. Before entering the fruit pomace dryer, the material needs to be thoroughly dehydrated in the dehydrator, Then enter a professional production and drying machine for operation, using a one-time countercurrent rotation method to reduce the moisture content to below 5%, without damaging the nutritional value of the original material, and without causing the problem of material burning. The finished material has a beautiful color and even moisture content.

The technical advantages and application scope of the fruit residue organic fertilizer dryer:

1. Using the instantaneous method of strong hot air to operate, the finished material presents a granular form.

2. The overall equipment consists of a drum crushing device, a heat source furnace, a spiral discharge device, an induced draft pipeline, and a dust removal device to prevent damage to the nutrition of the material caused by contact with the outside during operation.

3. By equipped with professional dehydrators, the finished product can be dried into the ideal moisture state in one go after operation, making it convenient for storage.

4. We can process 400 tons of fresh fruit residue per day, which can be done at once without the need for a second operation, achieving cost reduction.

5. The use of drum rotation as the operating mode, equipped with professional thermometers and instrument displays outside the drum, can better control materials to achieve optimal operating conditions.

6. The cylinder is equipped with a professional breaking device to prevent materials from clumping and sticking together during rotation. The entire process adopts a PLC centralized automation control system, making operation more convenient and safe.

The fruit residue organic fertilizer dryer is made using advanced and scientific technology. Due to its strong heat transfer ability and good drying effect, it improves the contact between fruit residue and hot air, which is beneficial for rapid batch production of materials. It has rotating blades that can be adjusted according to requirements and needs, effectively solving some of the drawbacks of traditional equipment. Considering the 24-hour non-stop working state of the equipment, a sturdy and durable steel cylinder is used to make the drum, Ensure the stable demand of equipment under long-term operation.

The working principle of pig manure organic fertilizer granulator: Various dry powder materials are added from the top of the equipment, degassed, spiral pre compressed, and transported to the curved grooves of two rollers. The two rollers rotate at equal speed and in reverse direction, biting the materials into the grooves and performing forced compression. The pressure that the materials bear gradually decreases after passing through the compression zone, and its surface tension and gravity cause them to naturally come out, enter the crusher and the whole granulator for crushing and trimming, Then it enters the vibrating screen for screening, and the qualified products are sent to the finished product warehouse or directly packaged through a conveyor. The materials under the powder screen are sent back to the raw material warehouse for secondary rolling through a feeding device. The size of the squeezing force can be adjusted by the hydraulic system according to the particle strength needs. By changing the groove form of the roller surface, materials such as flakes, strips, olives, and flat balls can be obtained.

The material is added from the feed end, the special structure inside the cylinder makes it into particles, and flows out through the discharge port. Due to the continuous entry of the material and the continuous rotation of the granulator, the mass production of the organic fertilizer production line can be realized.

The compost turning machine adopts the fermentation tank mode to produce organic fertilizer. It is a kind of organic fertilizer produced by putting the raw materials in the fermentation tank. The materials are turned, stirred and broken in the tank, so that the materials can be fermented, matured and degraded. It is easier to obtain stable product performance and better odor control effect than static composting.

The process of stabilizing organic matter in cow manure through the action of aerobic microorganisms (mainly aerobic bacteria) in the rotary fermentation composting machine. During the composting process, the soluble organic matter in the feces penetrates into the cells. Microorganisms decompose and metabolize a portion of the organic matter through their own biological metabolic activities, that is, oxidize and decompose it to obtain the energy required for biological growth and activity, and convert the other portion of the organic matter into new cellular matter, enabling the growth and reproduction of microorganisms to produce more organisms.
The wheeled self-propelled composting machine for cow manure organic fertilizer is more suitable for the mechanism and process requirements of microbial fermentation and storage of manure into fertilizer. It can effectively mix thick stored manure with microbial preparations and straw powder. Not only is the fermentation speed much faster than deep tank fermentation, but it also effectively prevents the generation of harmful and odorous gases such as hydrogen sulfide, ammonia, and indole during the fermentation process, which meets environmental requirements and can produce high-quality organic fertilizers.

Animal manure is a relatively high-quality organic fertilizer, which contains pure nitrogen, phosphorus (P2O5), and potassium (K2O) of about 1.63%, 1.54%, and 0.085%. Livestock and poultry manure must undergo maturation with a composting agent before application, to inactivate and deodorize parasites and their eggs, as well as infectious pathogens present in livestock and poultry manure, through the process of maturation. The production process of organic fertilizer from livestock and poultry manure is closely related to the equipment configuration of organic fertilizer production lines. Generally, the complete set of equipment for organic fertilizer production lines mainly consists of fermentation system, drying system, deodorization and dust removal system, crushing system, ingredient system, mixing system, granulation system, screening system, and finished product packaging system.

Organic fertilizer production equipment for livestock and poultry manure: raw material selection (such as livestock and poultry manure) → drying and sterilization → ingredient mixing → granulation → cooling and screening → measurement and sealing → finished product storage.

The process flow of organic fertilizer production equipment for livestock and poultry manure:

1. The ratio of raw materials per ton is 500 kilograms of pig manure (or other animal manure), 300 kilograms of auxiliary materials, 200 kilograms of bacterial residue, and 100 grams of RW bacterial agent;

2. Stacking, according to the above raw material ratio, according to the needs, the stacking length is unlimited, with a width of 4 meters and a height of 2 meters. When stacking materials, it is necessary to stack them layer by layer evenly;

3. Add the bacterial agent, expand the volume of the bacterial residue in a 1:5 ratio, mix evenly, and sprinkle it on the surface of the pile according to the number of piles;

4. Stir and ferment, use a blender to stir the pile evenly. After the temperature rises to 60 degrees Celsius or above, flip the pile every 4-5 days. After 15 days of fermentation at 60 degrees Celsius or above, fold the pile up;

5. Screening processing, fermentation is carried out according to the above steps, and after screening and deep processing, it becomes pure organic fertilizer;

6. Granulation refers to the granulation of fermented pure organic fertilizer. Choose granulators based on different raw materials, such as disc granulators, extrusion granulators, and integrated extrusion ball throwing machines;

7. Drying, cooling, and packaging: Newly made particles have a relatively high moisture content and need to be dried to below 20% of the organic fertilizer standard. The dried particles of organic fertilizer are cooled by a cooling machine before being directly packaged.

There is no need to add drying equipment in the design of organic fertilizer production line. It has the advantages of small investment, quick effect and annual output of 10-100 thousand tons.
These fertilizer granulator machines have their own advantages and disadvantages. According to the requirements of customers, the corresponding organic fertilizer production line can be designed. 
The roller granulator for cow and sheep manure organic fertilizer is mainly used for granulating various organic materials after fermentation, breaking through the conventional granulation process. The material does not need to be dried before granulation, and after crushing, it can be directly mixed to produce spherical particles, saving energy and achieving a higher granulation rate. With an organic matter content of over 97, pure organic matter granulation can be achieved without the need for adding binders during granulation. The particles are sturdy and beautiful, and can be sieved and rounded after granulation, reducing drying energy consumption. The moisture content of the raw materials can be between 20 and 50.

A complete set of granular organic fertilizer production line in the production of organic fertilizer choose granulator is also the main reason, some granulator production is round particles, some are columnar, some flat ball type, such as the production of particles can choose disc granulator, new organic fertilizer granulator, drum granulator, such as the production of columnar ring mold granulator, columnar extruder, Flat ball type choose to double roller press granulator. But all kinds of granulation equipment have advantages and disadvantages. According to raw materials, investment costs (drying does not dry), according to the needs of farmers, the choice of equipment is different. In a complete organic fertilizer production process, fermentation and granulation, grinding are the three most critical steps, so the fermentation pile turning machine and organic fertilizer granulator, organic fertilizer grinder in all the organic fertilizer equipment occupies an important role. Here we will discuss the problems that may be encountered in the production process in view of these two key links.

The small-scale organic fertilizer production line should also process the compost according to the use and market needs to be sold as a product. The purpose of composting is to improve the fertilizer efficiency and marketability of the compost products, so as to improve the comprehensive economic benefits.
How to choose granulator in organic fertilizer production? You can refer to the following information: for example, the production of particles can choose disk granulator, new organic fertilizer granulator, drum granulator; Select ring mold granulator and column extruder for columnar production; Irregular, flat ball type is selected to roll extrusion granulator (according to the mold);All kinds of granulation equipment have advantages and disadvantages. According to raw materials, investment costs (drying does not dry), according to the needs of farmers, the choice of equipment is different.

The raw materials for producing organic fertilizers are quite extensive, and the most common ones are animal manure such as chicken manure, pig manure, and cow manure. Such raw materials need to undergo biological fermentation and then meet the standards for harmless treatment. Thereby further making it into commercial organic fertilizer.

The process flow of processing fertilizer using organic fertilizer production line for poultry and livestock manure:

1. Fermentation: Collect poultry and livestock feces and urine, mix them with hay and rotten silage to make compost, and let it ferment. Only by timely and even flipping can the cow manure be fully fermented using a turner after fermentation. Some places are very dry now, while others are very wet, which can affect the quality of fermentation.

2. Ingredient crushing and mixing: The composted material, along with inorganic fertilizers such as N, P, K, and other additives, is crushed, proportioned, and mixed in proportion through a material crusher and a horizontal mixer using a batching bin.

3. Granulation: The material is granulated using a new type of organic fertilizer granulator.

4. Screening and return system: The granular material output from the granulation and forming system has differences in particle size and needs to be screened and graded. The selected rotary screening machine requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device. It is recommended to equip an automatic feeding system to screen out unqualified large and small particles, transport them out through a belt elevator, re crush them, and send them to a granulator for further granulation, which helps to improve the continuous operation capacity of the production line.

5. Drying: Use an organic fertilizer dryer to further remove moisture from the screened particles and meet the standard requirements for organic fertilizer moisture content.

6. Cooling: Using a cooling machine to cool the particle material helps to preserve the quality of the particle storage.

7. Packaging: The granular material cooled by the organic fertilizer equipment is transported by a bucket elevator into the finished product warehouse. The organic fertilizer production line can effectively solve the pollution caused by organic waste in industries such as livestock and poultry breeding, and improve the safety and quality of agricultural products by using automatic packaging scales to achieve quantitative weighing and packaging of granular materials. This lays a good foundation for the comprehensive consumption of green and organic food by humans, and the ecological and environmental benefits are extremely significant.

Organic fertilizer processing equipment has many advantages in processing and producing organic fertilizer. Through services close to farmers, land and consumer groups, we can find organic fertilizer products with scientific and reasonable formula, production characteristics and high added value, so that the whole industry can enter the track of benign development. The pace of grass-roots agricultural production should be combined with national policies to help farmers increase production and create income.
The bio organic fertilizer equipment among the organic fertilizer equipment has truly realized the development of agricultural cycle, which not only solves the problem of environmental pollution, but also uses renewable resources to turn waste into wealth. The organic fertilizer production line technology has planned to gradually promote the combination of clinker and chemical fertilizer, mainly with clinker supplemented by chemical fertilizer, and then slowly reduce the amount of chemical fertilizer, increase the amount of rotten biomass, and finally realize the use of only rotten organisms without or as little chemical fertilizer as possible, so as to realize the real circular agriculture, green agriculture and sustainable agriculture.

Huaqiang Heavy Industry Technology Co., Ltd. is engaged in the production and research and development of organic fertilizer equipment, compound fertilizer equipment, organic fertilizer production line, organic fertilizer production equipment, etc., but among the many technical equipment, the enterprise always focuses on the production and sales of organic fertilizer production equipment. The theme of the development of organic fertilizer production equipment in the market is to be able to achieve a better market development position, market development position is very important for each product and equipment developed in the market, in the market often see such a scene, that is, the closer the position of the product and equipment in the market, the less exposure in the market. And the best development in the market, that is usually in the market development position is relatively advanced, and is also the most active product equipment in the market, so they appear in the market times will definitely be much more than other products and equipment. This is also why equipment in order to grab the best market development position, and continue to improve their own market activity is an important reason. Almost half of the organic fertilizer production equipment in the market exists in a relatively rigid form in all walks of life, and it is precisely because they are too rigid that they do not have any new development achievements in the market, and gradually they will be forgotten by the market, and they will slowly lose their only spatial position in the market.
