The future development potential of organic fertilizer production lines is enormous. Due to the current agricultural situation in China, organic fertilizer raw materials are abundant and of high quality, and the market demand for organic fertilizer is also large. The scale of use of organic fertilizer is also very wide, whether it is farmland or vegetable cultivation greenhouses, or the beautification of fruit trees, flower gardens, and soil improvement, organic fertilizer is widely used. It also conforms to the national agricultural development policy, indicating that the prospect of organic fertilizer production lines is very broad.

The organic fertilizer production line is composed of many small machinery and equipment, each of which affects, restricts, and complements each other. After a certain process flow, high-quality organic fertilizer can be processed. The production process of the organic fertilizer production line is as follows:

1. The raw materials, auxiliary materials, and fermentation agents are pre mixed evenly through the equipment in proportion, with a moisture content of about 60. They are transported by conveyor belts and distributed to the fermentation tank through shuttle belt distribution machines.

2. In order to fully ferment the materials in the fermentation tank, a chain plate tipping machine is used to flip and shift the materials. At the same time, the aeration system is used to aerate the bottom of the tank, allowing the materials to undergo aerobic fermentation.

3. The fermentation of the material is basically completed in the fermentation tank for about 7 to 10 days. Under the flipping displacement of the flipping machine, the material is flipped to the discharge end, and then transported to the aging tank through the pool changing discharge machine, discharge belt machine, and shuttle type distribution machine for secondary fermentation of aging, so that the material is thoroughly decomposed.

4. The decomposed materials are transported to the granulation workshop through conveyor belts, and are screened and processed by drum screening machines and vertical crushers to remove large pieces of material;

5. The screened materials and other inorganic nutrients are proportionally transported to a dual shaft paddle mixer using a batching belt scale for mixing. Uniformly mixed materials can be packaged as powder products, and can also be granulated by adjusting the moisture content to around 40.

6. Materials with a moisture content of about 40% are produced into columnar semi-finished products through a granulator, which are then shaped into spherical granular semi-finished products through a shaping machine. They are transported by a conveyor belt to a tubular dryer for low-temperature drying, and then screened and cooled by a cooling screening machine to reduce the moisture content to between 15 and 30. They can also be coated and packaged as needed;

7. The finished particles are transported to the packaging workshop through bucket elevators and finished product conveyor belts, and are packaged using automatic measuring packaging scales and manually stacked.

The construction of an organic fertilizer production line has a market opportunity. Nowadays, people are pursuing a high-quality life, and their pursuit of food quality is also increasing. Under the strong call of national policies, more and more farmers are applying organic fertilizer, which has a long-lasting effect and contains various nutrients that crops need. Maintaining fertilizer and water can also prevent and control diseases and pests. The small organic fertilizer production line has a very broad profit margin and is an ideal project.

Livestock and poultry manure is a relatively good quality organic fertilizer. Livestock and poultry manure must be decomposed by a decomposing agent, and the parasites and eggs in livestock and poultry manure, as well as some infectious bacteria, are inactivated and deodorized through the process after decomposing.

 NPK fertilizer production line with steam drum granulation production is a process to achieve thermal granulation, by raising the temperature of the material, increase the solubility of the salt of the granulation water system, so as to achieve low moisture content to meet the needs of the material grain ingenuity of the liquid phase, reduce the thermal energy consumption of the drying process, improve the production capacity of equipment. Therefore, the quality of granulation performance of compound fertilizer equipment is one of the keys to determine the yield and quality of compound fertilizer produced by rotary drum granulator.

Next, Zhengzhou Huaqiang Heavy Industries will analyze the advantages and disadvantages of rotary drum type fertilizer granulator machine in the NPK fertilizer production line for you.

The advantages of rotary drum granulator in the NPK fertilizer production line
1, save the urea concentrate granulation, packaging, transportation and other costs, but also eliminate the solid urea compound fertilizer when broken, solid material meter, transportation and other troublesome operations.
2, urea solution directly involved in granulation, can make compound fertilizer production line granulation material granulation temperature from about 40 degrees C to about 60 degrees C, granulation moisture from 5% to 2.5%, greatly reducing the drying load.
3, the use of urea solution stickiness, in the granulation machine to help the material granulation, improve the granulation rate of the material, so that its production capacity increased by about 30%, the corresponding reduction of power consumption 30%.
4, compound fertilizer equipment products from the original 12N to 30N, the finished moisture from 2.0% to 1.00%, the appearance of the particles improved, the block situation can be slowed down.

The disadvantage of rotary drum granulation in the NPK fertilizer production line
1, anti-material more;
2, dust large;
3, power consumption is large;
4, the particles are not smooth and round enough;
5, compound fertilizer production line operating environment is not good.

Note on equipment selection of organic fertilizer production line, divided into the following six points:
1. Determine the size of the organic fertilizer equipment, such as how many tons are produced annually, or how many tons are produced in one hour. The size is determined before the price can be determined.

2. Determine the shape of the granules, which is the type of fertilizer granulator machine to choose. Is it powdery, columnar, oblate, or standard? The commonly used granulating organic fertilizer equipment includes: disc granulator, drum granulator, wet granulator, roll extrusion granulator, flat die granulator, ring membrane granulator. The selection of granulator should be determined according to the local fertilizer sales market. The shape of the particles is different, and the processes of the organic fertilizer equipment are also different.

3. Understand the configuration of organic fertilizer equipment, the configuration level is different, the price of organic fertilizer equipment is different, the amount of labor is different, the stable and high yield of organic fertilizer equipment is different: the general configuration is increased, automatic batching device, automatic Packaging device, automatic quantitative feeding device, cyclone dust removal and ink dust removal.

4. Choose the type of fertilizer produced, is it compound fertilizer or organic fertilizer? For the same output, the equipment for producing organic fertilizer generally takes into account the high water content, the strains are not resistant to high temperature, and the model is generally larger than the compound fertilizer model. Organic fertilizer types can be divided into four types, pure organic fertilizer, organic-inorganic compound fertilizer, biological organic fertilizer, compound microbial fertilizer, different types of organic fertilizer equipment is also different.

5. Selection of compost turning machine, the general fermentation forms are: stack fermentation, shallow fermentation, deep tank fermentation, tower fermentation, rotary drum fermentation, different fermentation methods, and different organic fertilizer equipment . Generally, shallow tank stacker is suitable for the principle of aerobic fermentation.

6. the level of environmental protection requirements, low environmental protection requirements generally choose heavy dust reduction, organic fertilizer equipment investment is low; places with high environmental protection requirements generally choose heavy dust reduction plus ink and dust, which can meet the national air emission quality standards.

The failure of the organic fertilizer production line will affect the normal working progress of the equipment, delay the production plan, and cause production losses. Organic fertilizer enterprises should implement strategies to reduce failures in organic fertilizer production lines, in order to save capital for enterprise production.

1. Maintaining the initial and basic state of the organic fertilizer production line, and maintaining the original design parameters: this is the most basic work, which means that the first step in reducing faults in the organic fertilizer production line is to restore the basic state of the organic fertilizer equipment;

2. Strictly abide by operating procedures, prevent and avoid destructive operations, and prevent and avoid overload operation: Most problems in organic fertilizer production lines are caused by improper operation or inadequate maintenance. The significance of standardizing employee behavior is to prevent and reduce problems in organic fertilizer production lines caused by such simple reasons;

3. Continuously discovering, preventing, and repairing natural degradation, allowing organic fertilizer production lines to be repaired in potential failure states: The significance of independent maintenance lies in the involvement of frontline employees in identifying problems in the first time, comprehensively standardizing production maintenance, advocating for the discovery and removal of six sources of activity, and a very important link is to solve the problem of the fault source;

4. Correct defective designs and carry out proactive maintenance with incidental improvements to the design and manufacturing defects of organic fertilizer equipment;

5. Prevent human degradation, avoid human damage, and prevent destructive maintenance;

6. Control any abnormal external conditions and accelerate the deterioration of organic fertilizer production lines.

No matter what equipment is used, it is inevitable that some malfunctions will occur. Perhaps due to equipment quality, improper use, or long-term wear and tear of parts, organic fertilizer production lines may also experience some malfunctions after prolonged use. Effective control measures for faults in organic fertilizer production lines, making judgments based on the situation, and timely maintenance.

The products produced by the organic fertilizer production line are based on fresh chicken, pig dung, mushroom dregs, and other organic-containing waste materials. They do not contain any chemical ingredients. They are rich in the Vatican, and chickens and pigs have poor digestion ability, which can only consume 25% of the Nutritional ingredients, and the other 75% of the nutritional ingredients in the feed are excreted with the feces, so that the dried product contains nitrogen, phosphorus, potassium, organic matter, amino acids, proteins and other ingredients. Chicken manure fermented chicken manure not only created economic benefits for the company, but also made a huge contribution to human environmental protection projects.

The company provides large, medium and small biofertilizer project, which have the following characteristics:
1. Simple structure and easy operation. The use of some beneficial microorganisms can promote the rapid decay of organic waste such as animal manure, and adopts a unique trough continuous aerobic fermentation technology to make organic waste quickly deodorize, sterilize, and mature in a short period of time. The purpose of recycling and reducing the amount of processing and saving the fermentation site, the fermentation cycle is 8-10 days, reducing the energy consumption in the fermentation process, and making the quality of the fermented materials and products more stable.

2. During the fermentation process, automatic control of the number of times the fermented material is turned over. Under the action of forward and horizontal walking power, the stacker auger continuously throws, breaks, drops the ground and produces the fermented material to the rear of the fermentation tank. A certain displacement causes the material to move back regularly and equidistantly in the tank, thereby forming a continuous aerobic fermentation process.

3. The design of multiple tanks under the function of the lift truck reduces equipment and facilities investment and realizes innovation in large-scale production.

The cost of organic fertilizer production plant includes the cost of organic fertilizer processing equipment, site investment and construction equipment cost, land rent, etc.
1. Processing equipment cost
Among them, the price of one trough tipper is 40000 yuan, the price of three silos is 8500 yuan, the price of one material grinder is 12000 yuan, the price of one drum screening machine is 10000 yuan, the price of one horizontal mixer is 13000 yuan, the price of five belt conveyors is 27500 yuan, the price of one packaging machine is 35000 yuan, and the organic fertilizer production plant cost is 150000 yuan.

2. Land rent
Because it is in rural areas, the price is not particularly high. It basically belongs to three types of industrial land, and the rent per mu is about 100000-200000 yuan / year.

3. Cost of plant construction
Among them, the higher investment is the cost of building the plant area. The construction price is about 300-400 yuan / m2. For the organic fertilizer production line with an annual output of 5000 tons, the fermentation tank workshop is about 700 square meters, the processing plant is about 500 square meters, and the warehouse and office area is 400 square meters. The total cost of building the plant area is about 350-500000 yuan.

4. Total cost
Among them, the cost of processing equipment is 150000 yuan, the average price of land rent is 150000 yuan / year, the construction cost of plant area is 400000 yuan, and the total cost is about 700000 yuan. If the industrial land of class II or above is selected, it needs to be calculated separately. 

Organic fertilizer production equipment in the process of processing organic fertilizer, will produce a lot of dust, if not handled properly, will cause serious dust pollution. However, the organic fertilizer production line of our factory has less dust and more environmental protection, which is mainly realized by bag filter. Today, Huaqiang heavy industry small editor will explain how to reduce dust and environmental protection in organic fertilizer production line

The equipment in the production workshop should be completely closed at each blanking point, and the exhaust pipe should be installed. It ensures that the odor and dust in the organic fertilizer production process are leaked out, and the dust generated at the dropping point is then pumped into the bag filter by the induced draft fan. It is basically dust-free.

The inside of the bag filter is composed of several bags. The dust is filtered out by the bag, and the wind is discharged into the atmosphere through the bag. The bag filter is equipped with high-pressure blowing device in each bag. The dust on the bag is shaken off instantly by synchronous action of solenoid valve and time relay. Through the unloader at the lower end, the uniformly collected dust is discharged into the mixer, and the fertilizer is recycled. 

The design of chicken manure organic fertilizer pellet fermentation production process design includes:
1.Efficient compound bacteria and its propagation technology;

2. advanced raw material allocation technology and biological fermentation system;

3. the best special fertilizer formula technology (can flexibly design the best combination of product formula based on local soil and crop characteristics);

4. Reasonable secondary pollution (exhaust gas and depression) control technology;

5. Design and manufacturing technology of organic fertilizer production line equipment.

The more complicated process of chicken manure organic fertilizer production line is as follows: organic fertilizer raw materials (animal manure, domestic waste, dead leaves, biogas residues, waste bacteria, etc.) are fermented into a semi-wet material grinder for crushing, and then nitrogen is added. Phosphorus and potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) make the contained mineral elements reach the required standard, and then have a mixer to stir, and then enter the fertilizer granulator machine to get granules, after drying, screened by a sieving machine, qualified products are packaged, and unqualified returned to the granulator for granulation.

Among them, the reasonable mix of fineness of raw materials is very important for the organic fertilizer production line.

The fineness of the whole raw material should be matched as follows: about 100% to 60% of the raw materials account for about 30% to 40%, 60% to 1.00㎜ diameter raw materials account for about 35%, small particles with a diameter of 1.00-2.00㎜ about 25% -30% The higher the fineness of the material, the better the viscosity, and the higher the surface finish of the granulated particles.

However, in the production process, the use of ultra-high proportion of high-fineness materials is prone to problems such as excessively large particles and irregular particles.
